OpenEVSE new user interface, testers & translations needed

doggy · 14 February 2023 03:01

Thanks. Do you know where to find this fix? I am building from 8.2.2 source as of 24th December and cannot see any issues listed for it.

Is your evse compiled with AUTO_AMPACITY? ( for Untethered charge cable )

The discussion is here:

github.com/lincomatic/open_evse

AutoSetCurrentCapacity() should set a max current capacity not actual charge current.

PP_AUTO_AMPACITY fw have problems with wifi module. When a charge is started by …the wifi module, and a charge current value has been set previously ( so wifi module sent an $SC command ) , AUTO_AMPACITY fw will check AutoSetCurrentCapacity() and set a new charge current value, overriding previous one. Charger then starts it charge at full amp capacity instead of setted value. This cause problem with Divert mode and Shaper and any automation using settable charge current. This is also a security issue as it can override the main circuit braker depending of house load. AutoSetCurrentCapacity() should set a new Soft_Max_Capacity variable to not interfere. This should solve #155 and some other issues pointed on OpenEvse Wifi git

But seeing your 6A bug, is it working now you have set once the divert active?

I think I’ve already saw something like an uninitialised value for the divert/boost switch endpoint.
( When I setup divert the first time it’s always set to disabled ( i-e boost/speed mode) )

@doggy countdown and float display should be ok with latest commits.

doggy · 15 February 2023 01:03

Yes it is set for auto ampacity. Thanks for the info.

I have been testing the latest version of UI2 today and it is going well so far. Thank you!

doggy · 15 February 2023 02:31

Yes…

doggy · 17 February 2023 00:10

Just a progress report. I’ve been using the latest UI2 for a couple of days now on two cars, manual and divert. Plus testing reboots and upgrades. Plus energy and time limits.

Everything is great. I have not detected any problems at all.

Regarding the Ampacity fix, I have done a build with that added to my 3ph/1ph EVSE firmware and it is ready to go into my OpenEVSE (including enabling the button menu). Not sure when I’ll get to try it, but hopefully within the next few days.

One thing. On the self production page, if you hover over the three start/attack/decay entry fields, it says to enter a valid value with the two nearest valid values being 0 and 1. Is this correct? I am using numbers like 0.7, 0.8, 0.1 and thought they were okay?

I tried the latest build and when using solar divert, set point is set to 9A, currently charging at 9A but available is 7A. How come it isn’t coming down based on what’s available? I swear it was working before…

If you’ve set manually charge_current using the slider, then It overrides the Divert command.

I had another weird period where it ran at maximum charge when it was in ECO divert and should have gone off. When I checked the web GUI it had switched to “enable charge” on that 3 way switch. I’ve attached a graph again, which hopefully makes sense.

Normally I feed it the difference between “Solar production” and “Consumption minus current EVSE consumption” via MQTT. When this is negative and solar is >800 (in this instance) I send 1600W on the MQTT messages to get a minimum 6 Amps.

You can see here when the solar was <800 and the ~ECO fudge I have was dropped: the MQTT feed would have said said (799 - (4273−4057)) = 583W, then OpenEVSE responded by jumping up to maximum current! You can see a gap here where the EVSE charge current dropped to 1600 again since solar was >800 and so it was getting the MQTT 1600 messages, then it jumped back to 4000 when MQTT said <800.

Earlier today I did run it for a period on maximum to recharge after a trip to the coast yesterday and ready for a big driving day tomorrow. But then I did select ECO & AUTO again a few hours before this happened.

Any ideas what happened? Is Smoothing Attack = 0.3 and Smoothing Decay = 1.0 causing problems?

The live dygraph is here (for the next 8 hours):

then it rolls over here (for 24 hours):

I don’t think that is the best thread to ask for divert problem. I’m no help here, I don’t know much about this, and not using this feature.

fraz · 20 February 2023 18:08

Ah sorry. I mentioned it here only because it seemed a new problem in this version. I’ll pull the divert decay back to 0.8 (I used lower values with the previous firmware) and watch for it happening again, then start a new thread later.

Otherwise the new interface is good! Thanks.

doggy · 21 February 2023 03:13

Any info on the above?

Guillaume_S · 21 February 2023 09:14

@doggy, thanks it was a bug in the inputForm component ( missing steps for float number ) . It’s fixed.

@pdhoogh I’ve also found why you had only 2 icons in the nav with your network problem. In offline mode there was missing cached icons. Fixed too.

doggy · 21 February 2023 09:57

Thanks!

Does the History page look too spammy, chatty? Ideally I can quickly find out the total energy per session without scrolling a huge list like this.

It would be good to even set Miles/kwH in vehicle setup so you can display estimated miles gained in addition to energy.

Guillaume_S · 23 February 2023 08:04

There has no change on the fw log part, so it still displays the same thing as on previous UI.

But I’m agre the evse log manager should log only state change if vehicle is connected and charge sessions, + faults

Guillaume_S · 23 February 2023 16:07

new feature in the UI.
In Configuration / Firmware , there’s now a box to backup config and import it back.

Credentials data are not exported in the backup.

doggy · 23 February 2023 21:12

Installed okay.
Nice!

Guillaume_S · 24 February 2023 11:23

@doggy, I’ve submitted a PR that should fix divert with threephase enabled. It only factorise by 3 the voltage in idvert calculation when Threephase switch is enabled.
Would this fix your issue without having to trick the Level mode ?
