4-wire-version

[SchallertDK]

Where in the "PlatformIO" do i find the "4-wire-version" as is mentioned in the files??

"3) Software
6-wire and 4-wire versions
DL and install Visual studio code: https://code.visualstudio.com/download
From within VSC, click on Extensions icon (ctrl+shift+X). Select PlatformIO IDE and install.
From the new platformio icon, open folder “6-wire-version” or “4-wire-version”."

It's in the "Code" folder of the project.

[SchallertDK]

Thanks a lot,
And where do i find the file "model.h" to choose my model (Miami):
"Choose your model in the file “model.h”. Only one model may be defined.
Double slashes ‘//’ means the line is commented out. To change model,
comment out PRE2021 by putting // in front of that line. Remove the ‘//’ from
your model."

I can find the "model.h" but i cant see where to choose my model?

Hi! First figure out what model you have. Look on the pump for a number. Next find out how many wires goes between display and pump. If 4 you need to be able to determine which wire is what. (Using a DMM and/or looking at the pcb at the display or pump)
Report your findings here and we can point you in the right direction.

Hi. Thanks for your help. The pump is with 4 wire, and the cables are mounted as you see at the attached picture. The pump is model #54123 Best regards

Yes.

[SchallertDK]

As my picture shows, i have GND - TXD - RXD - 5V at my pump print, hov should they be mounted at your print? (H3 and H4)
5V is in the square and GND is under that (comparing to the 6 wire setup?) but i dont see what D3 and D2, and D6 and D7 should TXD and RXD

[SchallertDK]

[visualapproach]

I'll reply tonight. Busy now

[SchallertDK]

No stress, answer when you have the time for it ;)
Your print is first arriving 19.04.22 :)

[chunkysteveo]

This image should help - your display goes to the bottom set of 4. Your pump unit 'CIO' goes to the top set of 4. 5v is the top pin on both. GND is the second to top pin on both, next to the 5V. For my pump the white with solid red dash went to pin 3 (counting from top to botto), and the white with red X 'cross' went to the 4th pin. Replicate the same on both sets of 4 connectors. If you don't get any control of the pump when testing the two wires may be the wrong way round. You won't damage anything if they are, just don't get the 5V and GND messed up.

You will need to twist them as shown, as the connector is 5v-data-data-GND, but the PCB is 5v-GND-data-data.

Good luck!!

Hope that helps.

It is also saved at the beginning, but then after time when i'm entering the IP adress again to see, then it is reset again?

[visualapproach]

No shouldn't do

[chunkysteveo]

Hmmm, there may be an issue with the 4-wire version - i've noticed my chlorine and filter timers never seem to "stick" between reboots, and my cost per kWH would always reset back - like the settings were never being saved.

Never stopped to diagnose or troubleshoot it, but there may be an issue there with retaining or saving settings.

[visualapproach]

Ok I'll look at it

[chunkysteveo]

OK did some testing to be sure - on a 4 wire.

I click the red "Reset" buttons to reset the Chlorine and Filter changed days to 0.0 days. I set the Spa Config Price per kWh to 0.2 and save. And I then reset the ESP using the red Reset ESP in the menu.

Here's the settings.txt file after saving, and then after a reboot - the savetime shows it's been overwritten on reboot maybe? But you can see the second settings.txt json object shows the values have been "reset"?

There was a bonehead mistake in the setup. Variables were initialized after settings were loaded. Fix uploaded in the development version now.

[SchallertDK]

Since it's not working, i maybe had made something wrong?
Today i try downloading the development code
https://github.com/visualapproach/WiFi-remote-for-Bestway-Lay-Z-SPA/tree/development

But there is no PlatformIO file to open, in this "code"?

[visualapproach]

But there is no PlatformIO file to open, in this "code"?

No, the "platformio.ini" is in the 6-wire / 4-wire folder, just as when you did this the first time.

This should do what you want. Take control must be active ofc.
Set target:38 2022-04-29 08:00:00 interval: 604800s (this isn't really necessary if you don't change the target temperature manually or reset the esp)
Set heat:1 2022-04-29 08:00:00 interval: 604800s
Set pump:0 2022-04-29 20:00:00 interval: 604800s
Set heat:1 2022-04-30 08:00:00 interval: 604800s
Set pump:0 2022-04-30 20:00:00 interval: 604800s
Set heat:1 2022-05-01 08:00:00 interval: 604800s
Set pump:0 2022-05-01 20:00:00 interval: 604800s

Check if the ESP restarts unintentionally. You can see last restart on the SPA Config page.

[SchallertDK]

I think i'm not understanding how the update to your fixed files is working?
Can you send me the link, so i'm sure it is the right code i'm downloading?
It is maybe not the one i linked to, that i should use?

The last reboot was 13.00 (1 pm) - And it wasn't me. So the spa was off when i went home at 3 pm.

[visualapproach]

build instructions ch 3:

OR upload files via web ui menu "upload files". It's the files in the "data" directory. You may wanna go this route to save previous settings. Only upload .html and .js files.

But you have a problem with the ESP resetting. Bad Wi-Fi or maybe bad power supply? (some 4-wire pump appear to have problem deliver enough current according to users)

[SchallertDK]

This is also the way i'm doing. But my question was if it maybe is the wrong files i'm using/uploading?
You told you had found somethings and fixed them, but the only files i can se recently is changes at the 4 pin files, is not in the master directory, but in the development.
Maybe many at the faults is because of the maybe missing constant 5v power as you says can happen?

[visualapproach]

extract all files. Start VCS. From platformio open project, browse to 4-wire.

[SchallertDK]

I have tried that, but PlatformIO says it cant open because there is no PlatformIO file, as there is in the "master" zip file. Because this I can open with no problems

[visualapproach]

Yes there is!

[SchallertDK]

Yeah okay, Now everything went smooth with no errors.
So the issue with the factory settings at the ESP Module is the 5 volt power who maybe isn't constant?

[SchallertDK]

Hi agian,
Again i lost the connection to my module. Why do this happen?
I have to unplug the module from the spa, and reinstall everything and get af new ip adress.
This is second time

[chunkysteveo]

Use a static IP from your router maybe?

[SchallertDK]

I really dont know how and what to do.
In the index - network config i choose static ip and typed the ip, but the nothing worked
I tried to start all over again with downloading af new code and installed it.
Everything seems good, but at the computer where the esp is conected and got the setup, i can connect the ip adress, but from my phone on the same network i cant? I know i has done something wrong, but cant figure out what it is?

[visualapproach]

You shouldn't need to reinstall it just because the IP changed. If that's the problem...
We cannot help with the sparse info you gave. You need to give all the details about your problem and exactly what you do if anyone should be able to say anything useful.
Things we don't know:
Where is your layzspa? 1 km from the router behind a reinforced wall?
What router do you have?
What IP did you enter? Screenshots?
What's the IP of the router and what's the network settings? Reserved addresses possible?
What phone and IP?
etc etc

The more info you give the more likely someone is to be able to help you.
