4.1.5 started having issues in eco mode, needed a factory reset

[pdhoogh]

4.1.4 had issues that were documented and Jeremy Poulter had some fixes in patch releases for 4.1.4. I installed and tested those. They seemed to work OK with PV Power Ratio = 1. No complaints.

Then 4.1.5 was built as the latest release and I installed it. Soon after the OpenEVSE started misbehaving.

The day before yesterday, at night, I plugged in the EV. OpenEVSE was in eco mode. There was no solar. The patched 4.1.4 worked correctly: it would wait for sufficient solar next morning and start charging the EV with throttled current. Not 4.1.5 so it seems. It started charging the EV and let current go all the way to max (set 15A) without solar. I tried a number of different things like resetting the WiFi, resetting OpenEVSE, power cycle, turning override on/off several times... nothing worked, OpenEVSE kept charging. WiFi was working and Power1 was updated correctly, but I noticed that the double Smoothed Current indicators on the GUI were not updating.

I waited till today to try again during a sunny day. Behavior was erratic. I was not able to find a systematic (mis-)behavior. as the plots below show, sometimes it would throttle correctly, sometimes it gives up and moves the charge current to max. Look at Power1 as the best indicator for the OpenEVSE intermittently not throttling:

I will moved the WiFi version back to Jeremy's patched 4.1.4. It did not help.

So I did a Factory Reset. And reconfigured everything on the OpenEVSE from scratch. I am still on Jeremy's latest 4.1.4 patched firmware (21 Sep). OpenEVSE now does no longer start charging the EV without solar availability.

What went wrong here? I'm not going to 4.1.5 again until we (think we) know what happened. Is it necessary to do a Factory Reset and reconfigure everything if you want to upgrade to 4.1.5 ?

After upgrading to 4.1.5 I was unable to save settings. There was no error message, my changes just disappeared at the next screen refresh.

I also did a factory reset. So far my changes are not being saved.

I’ve seen this behavior with WiFi not being strong enough. I was able to save settings.

I went back to 4.1.5, did a Factory Reset and then reconfigured everything. Then connected the EV and it went back to max current - sigh - but after a while it started throttling. So I changed the “attack” from 0.8 to 0.2, switched to “Fast” charge and then back to “Eco” and it started to behave as expected. It did not need that in 4.1.4.

Hi Jeremy, Away from home for a while. Will take a few weeks before I can get to this. ——————————— Philippe D’Hooghe Meidoornlaan 10 9820 Merelbeke +32 485 655 669 maandag 24 oktober 2022 22:09 +0000 van ***@***.*** ***@***.***>:
