[tomganleylee]

just came across this, looks great project, I've got a 6pin version as well,

when I get a chance ill try and add MQQT support to it.

also design a single pcb for it, (happy to send one to you)

[visualapproach]

@tomganleylee Thank you! Looking forward to improvements :-) I just uploaded a newer revision that you can use as a base instead. A little prettyfied code and some small functions added /Thomas

[faboaic]

Thanks so much for your project.
I have a lay-z-spa Miami and at least the display looks the same.
I never had it open until now and will check.

MQTT support would be perfect feature to integrate the lay-z-spa into house automation with node red.
I have 20 kWp photovoltaics and automatically pushing excess PV power into the lay-z-spa instead of regulating it away and leaving it lying on the roof would be great.

I have all the parts except the level shifter.
So it will take a little time until I have the project up and running.
But thanks so much :-)

Cheers,
Fabian

[tomganleylee]

Visualapproach has done a great job, I have built the circuit and programmed the esp, going to test it tommorw. Also putting a PCB together for it. To make it look nice :). ( I will upload the files ) Hopefully start mqtt next week ( I have 5p energy at night

@visualapproach really excellent work, thanks for sharing. I have all the required parts and will build and test within the next week. Also as an mqtt user any improvements will be much appreciated.

When I read the code I realise I was very far from getting this working myself :)

Is the nodemcu powered from the 5V line of the 6pin connector?

[visualapproach]

@877dev Yes, it is powered via the 6 pin cable (5 V to Vin). I hesitated at first since I didn’t know if it would support the extra load. But it did :). At least in my case. First I used an Arduino nano + esp-01 and a dc-dc converter for the 3.3V side and a trafo for the Arduino. But it was really tempting to get rid of all the extra stuff so I tried. Also the step to an esp-12e meant that I only had to program one device which is neat.

[LavaTiger99]

MQTT would be awesome, then I can integrate into HomeAssistant!

[byles]

Thanks @visualapproach , I only got as far as analysing and decoding, other real life commitments get in the way :( can't wait to try this next weekend! I'd contribute mqtt and pcb design but for sure somebody else will beat me to it.

If you're in the UK you can find the connectors on Amazon: https://www.amazon.co.uk/sourcing-map-Plastic-Terminal-Connector/dp/B07GT51DZ2

If you're not, at least it gives you a description of what to look for.

[visualapproach]

@byles Thanks, good find on the connector!

[byles]

I only used two, if you have any trouble sourcing them I'll happily send some your way!

[hhovde]

Hi!
Nice work @visualapproach.
I stumbled up on your solution via another project; https://github.com/ximon/Hot-tub-remote
Both of which I found during research for my own design.
I started tinkering with my spa last year, but are under heavy time constraints atm. and where looking for a turn-key solution, but mine is a 4-pin version. ( Best I found so far; https://github.com/mrQ000/layz-rc )

@byles - I believe the connectors are called "JST SM Connector"
I ordered some of those for my pump last year (4 pin) and they fitted nicely.

/H

[LavaTiger99]

@visualapproach, Can you please upload a picture of the back of your device? I want to see how you laid it out. Thanks!

[877dev]

Here’s the cables I got, confirmed working on Vegas 6pin model:
https://www.ebay.co.uk/itm/323733997560

Some description of how the code works would be most interesting, it’s way way beyond what I could create but I like to at least be able to read the code 😂

[byles]

Damnmit! I spent ages crimping the tiny little buggers... think I'll get them from eBay too! Cheers @877dev

Ahh, out of stock! 😂

[visualapproach]

Yes I will try to put something together.

[Bankaifan]

Hi dwoosnam, keep us up to date with your project please. Might be pretty interesting for everyone. We already know, that with the 4-wire-version the communication works completely different – hopefully the 6-wire-version use always the same protocol Von: dwoosnam ***@***.***> Gesendet: Mittwoch, 24.

[dwoosnam]

I can't tell if i've made a mistake or, the wiring is different. But my trials today were met with failure!

[sjeffrey101]

have you got any further on this, my Egg has died (the heater) i was considering buying one of the new units, but not if it doesnt work with this,

[dwoosnam]

Other than my previous post with pics, no. Life got in the way. Though I did order some breadboard and a new LLC to test at some point.

[dwoosnam]

@Bankaifan @sjeffrey101 Moved over to #54

[kiplin1995]

Fantastic project - hoping this gains even more traction this hot tub season!

After a few days of fiddling about with the 6pin version and failing to get the sketch uploaded to the ESP8266 I went outside to discover I have the 4 pin version anyway...
Since then I've managed to upload to the board via USB in VS Code and I've also got the board connected to my router.
However when I navigate to the IP in the browser I just get 404: File Not Found

I'm pretty new to all things arduino based and the like but have a fair amount of programming experience (mainly Windows apps in C#) so i was hoping I would find this easy to follow but I'm at a loss.

I think I have the write files pushed to the board? But not very confident in this so any help appreciated!

Cheers

[dwoosnam]

I feel like I had this because I hadn't uploaded the LittleFS files. Was using Arduino IDE though, so not sure where you'd find that in VSc.

[kiplin1995]

visualapproach replied just below but yes essentially I hadn't uploaded the filesystem image - thanks

[visualapproach]

[kiplin1995]

Makes sense re. it waiting for the CIO to give a response. Hopefully that problem will disappear when I test it out.
Not sure what my approach is going to be with testing it on the #54123 model given it was written for #54138. Unsure as to how to work out which PIN should be what so welcome anyone's thoughts on that.

[JoelMSawyer]

@kiplin1995 Did you get it working reliably with your 4-pin? Might attempt similar on my #54154, which I believe is also 4-pin. Also interested if anyone else has tried this pump!

[kiplin1995]

@JoelMSawyer Yes and no...
It does work but is somewhat temperamental. Every now and again it just stops the pump and I may not notice for a few hours or a day etc. which is frustrating as it may have cooled down significantly.
Also the web UI can be slow to respond sometimes (this could be to do with my home network but everything else is super fast so not sure).

Also I've found that if the web UI is loading for a few seconds the pump stops and starts which can be annoying.

Was easy enough to implement but its not a perfect science I dont think.
I've tried flashing the latest code and it stopped working entirely so have had to roll back.

Keen to hear other's experiences

[JoelMSawyer]

Thanks for getting back to me. Guess I'll leave it for a bit, hopefully some information on my specific pump is posted, and the 4 pin software variant is further developed!

[visualapproach]

@kiplin1995 I changed the pinouts to match my PCB. Just change them back if you like. I don't think there is something super exiting about the latest version right now, but just so you know.

[Handy-Harry]

Made my board this weekend. Ordered the pcb at jlcpcb for the first time.
Connected it to my node red server.
Everything up and running.
The only thing I need is good weather.
Thanks for your effort.

https://youtu.be/-NvA2snQVXM

[visualapproach]

Thanks for the report. It's tricky on this pump because there will be a fight between who is controlling the pump. We can't tell what target temp in the display is set at. It is internal to the display, and we cannot tell the display what it should be. Other than pushing its buttons. So we just feed it data to shut up whilst the ESP is in charge. And the ESP never sends an actual "target temp" to anything. It just turns the heater on or off depending in its reported temperature. Just like the display does.

Regarding the suspected bug - Yeah I know how you're thinking. It's actually there on purpose to stop updating the slider whilst you try to slide it. The intention is to update it ONCE only. When loading the page. And then it's up to the user. However it isn't always working. The slider value upon refresh is 0 but the lowest it can show (by design) is 20. So there is surely improvements needed, but skipping the IF will likely cause problems when trying to change the slider value.

[kiplin1995]

Ah ok i see what you’re saying.

Aside from that the issue I’m having now is that it seems to turn off sporadically.
Sometimes it’s just that the pump and heater stops for a couple of seconds and then continues but after several hours the whole unit just stops. Power is still there and I can still access the UI but no pump or heater.
For example at about 11pm last night it had got up to about 36°C but this morning the pump and heater are off and it’s dropped down to 14°C 😓
Any thoughts on that one?

EDIT: not as bad as I initially thought, just the water in the pump and pipes was down to 14°, turned it back on and after a minute or two it had drawn water through from the tub and it’s at 33° but still odd that it had turned off in the last few hours and temp is dropping

[kiplin1995]

Ok it today fell over today - wouldn’t connect to wifi when I was restarting the egg to try and get a connection.
Took the lid off and I’m pretty sure some of the connections I made between PCB and DSP/CIO are loose.
Perhaps this is also the reason for it being unstable yesterday and overnight.
Too much rain today to faff about but will look at it more closely in the week.

[visualapproach]

Yes that would be bad for the functionality :-)
If it feels unresponsive there is also a chance it has gone into AP mode (check for wifi access points). It can happen if wifi is poor in the area.

[kiplin1995]

I’m really hoping that’s the case. I took the board out and supplied it with 5v on the bench and all seemed well. So assuming it’s the made up plugs I’ve got between the board and pump.
I had the same thought around AP mode but I did check for that and it wasn’t the case.
Think it just lost power completely

[flixlix]

I'm sorry for the stupid question ^^, but I can't figure out how to order the PCB's, can someone help guide me in the right direction? Thanks in advance
Edit: Btw, I didn't understand if I really need the PCB or not

[flixlix]

Ok, it's kind of working now:

I changed the dsptx back to its original pin and edited the file according to each pin. It now shows the temperature and I can control it with the toggle "Take Control" turned on. I don't know if it's supposed to be like this, but on the display the buttons aren't in sync, for example: I turn on "take control" and "Bubbles", and the pump turns on bubbles, but the display still doesn't turn on the bubbles button.

Another weird thing (I timed it) is that after 6 minutes the E13 error decides to appear.

Other than that it's working fine.

How can I resolve those two issues?

[flixlix]

Update:
I installed the Spa. It works for a few minutes just fine, but after some random amount of time I start getting the E13 error. It seems to not like me turning on "Take Control" but somteimes also goes to error mode even if I didn't "Take Control"
After a little bit of time in error and beeping on the Display, I get a E48 and E01 on the UI. Turning off power to the Spa and back on works most of the times, although sometimes that evene doesn't work.

[visualapproach]

It's the way it is. Can't do anything about it (without modding the hardware) due to the way the pump is designed.

Regarding the errors according to google,
AIR JET PUMP ERROR CODE 13: Internal communication error code.
AIRJET PUMP ERROR CODE 01: Sensor or Water Flow Error.
E48: ???
I guess the water flow gives an error because the communication stopped working. Not sure though.
Why you get E13 is hard to know. Maybe some flaw in the code, or hardware problem. If other people can confirm it works with their setup we can exclude the code from the list of suspects. Although I tested it for several hours when I had the pump. Maybe just luck

[flixlix]

Ok, the part of the buttons being out of sync is fine for me.

What I already tried to do to resolve the issue was putting all of the "goodies" inside a different enclosure, that lets the air flow, so the ESP doesn't overheat, because I notice it was getting kind of warm. This unfortunately didn't work, since when I plug it in, after a few minutes (seems to be random) it disconnects. Is it worth buying a JST-SM Housing Connector to make sure that the connection isn't bad?

[visualapproach]

I haven't regret buying the connectors. Pretty cheap and it is more robust. Can't promise they will solve your problem but it won't hurt either.

[flixlix]

Just a quick announcement;
I have these 4 spare boards, if anyone is interested, please feel free to get in contact :)
I am based in Portugal.

[Grebiman]

Hi flixlix,

is it possible to get 2 boards?

Thx
Peter

[flixlix]

Hi there! I would like one of the boards :) how can we get in contact? Thanks.

Hi @randy993 , sorry I didn't see your message, if you're still interested please send me an e-mail at [email protected]. Thanks

[flixlix]

Hi flixlix,

Hi @Grebiman since I still have 3 empty boards, yes it is possible :)
Please send me an e-mail at [email protected]. Thank you

Hi @randy993 , sorry I didn't see your message, if you're still interested please send me an e-mail at [email protected]. Thanks

No problem, but I ordered them myself some time ago. The shipping cost probably wouldn't have been cheaper than ordering myself. Thanks for the response though.

Ok, I just didn't want the boards to go to waste, since I could only order 5 and just needed one, but I can totally understand that it probably doesn't make much sense from a cost standpoint. Still thank you for your interest and have fun with your Project! :))

[Bankaifan]

Hi, I have a quick question - my Webinterface gets slower and slower. Right now it does not even send MQTT-Commands anymore. The Dev-Tools say, the websocket.js is the problem.
Can this be a storageproblem? Any ideas how to investigate this further?

[visualapproach]

Don't know. The script is running on your browser, not on the ESP. The ESP just sends the file to the browser.

[Bankaifan]

Hm. The startup of the pump is also slow. Run in a few seconds - now takes up to 5 minutes. Browser says, websocket.js is not available

Check WiFi is good at the pump and maybe reflashing the ESP will help? Doable over the air.

[Bankaifan]

Found the problem - the mqtt-broker was not reachable what seems to freeze the esp.
Restarting the broker und rebooting the esp solved this.

Hi,
can I use D1 Mini esp8266 as well instead of NodeMCU? Has anyone a link where to get the JSM SM 6 pin connectors? Thx!

I'm going to test it on the Miami 2021 version, anyone here had success with that version?

[visualapproach]

Hi!
Yes but it wont fit the provided PCB.
I bought my connectors at WISH.COM

[jlockham]

Help a noob out here - i have tried in both VSCode and Arduino IDE to get this runnin gon my nodemcu, but cant get it to work.

Upload the program, all fine. Upload the data - no errors. Serial monitor shows its booted, and give the Ip of the nodemcu. then jsut put a . on teh screen, every second or so........

I can see the wifi on my iphone, connect to it - iphone gets ip address. Open safari on iphone, and go to 192.168.4.1 and jsut sits tehre for ages, but never loads a page.

tring to use the master - 6wire version (without mqtt)

cant get on any of the 'web pages' - so cant actually set the thing up.

What have i done wrong (note, only powering the device from the usb)

[jlockham]

yep - that i am using (tried Arudino and VSCode) - now jsut using VSCode with platformio... still same result
I have followed your latest 'install doc' to the letter (as far as i can tell...

[jlockham]

so jsut tried it from an android phone - and get the same thing, connects to teh AutoPortal wifi fine - then says theres no internet connection - and you press yes to stay connected, then nothing. so open chrome, and browse to 192.168.4.1 and nothing loads (not even a 404 page not found)

[visualapproach]

I can confirm the problem. Will investigate...

[jlockham]

ok, thank you

[visualapproach]

WiFi manager library wasn't working in non blocking mode. Reverted back to blocking auto portal. Try development branch again and it will most likely work.

[Grebiman]

Hi,

it works, but the display is flickering. I checked all the connections, resoldered it, but no change...

Any ideas?

Best regards
Peter

[visualapproach]

Maybe you shouldn't have resistors on 5V and GND. Remove them and try again. (Pin 1 and 2 if I remember correctly but check it out in the docs)

[Grebiman]

Now it works perfectly, great project and many thanks!

[visualapproach]

Good, you are welcome! What's your spa model?

[Grebiman]

Miami

[visualapproach]

thx

[mod24]

Hello @visualapproach,

Just wanted to let you know (for documentation reasons) that I can confirm that the Bali Model from 2021 (square, 6 wires, no hydrojet) also works.
I still have the display flickering, but suspect to get this solved as soon as the 560 ohm resistors arrive.

Also wanted to thank you for this great project and the effort you put in.

Regards,
ofri

[visualapproach]

Hello @mod24 great! I'll update the docs.

[mod24]

Can now confirm that the 560 Ohm reistors fixed the flickefing and also the buttons work now.

Automation together with NodeRed also works like a charm.
Absolutely awesome now!

Thanks again @visualapproach for creating and maintaining this project.

Did you define the correct model in BWC_8266_globals.h?

//uncomment your model and comment out the rest
#define PRE2021			//the older one, no hydrojets
//#define MIAMI2021		//no hydrojets
//#define MALDIVES2021	//hydrojets

Not super intuitive yet, but maybe in the future I'll make it easier.

[PLhome]

No, I did not change that, I will do this in the coming days and let you know, thanks for replying!

[PLhome]

It did not work, I bought the jaccuzi two years ago so I tried PRE2021 and MIAMI2021 and I even bought a new Node mcu but no change in functionality, no lights on the display only the temperature. I went over the wiring at least a dozen times and all is according to the documentation. Any help will be appreciated!

[visualapproach]

Try the development version and look at startup on the pump. Does it show hello, IP and cycle through all LEDs? (And play a melody?)

[PLhome]

Tried the development version but no change! I never have seen any leds on the pump display and I don't hear anything!
