OMODA/Jaecoo

[waynedn]

I have recently installed the OMODA/Jaecoo charger for my OMODA C9. It appears to be a Telluspower charger with model number TP-EVVA-O32ASS.

It says in the manual it supports OCPP V1.6/WSS. It doesn't have the "j" after the 1.6.

I can pick it up in home assistant for a short while. It retrieves values from the charger and starts displaying them in home assistant. It shows reconnects increasing every 10 or so seconds and then it seems to lose connectivity after about 7 reconnects and becomes unavailable. The notifications in home assistant shows this as the charger rebooting each time it reconnects.

Once home assistant stops talking to the charger, I can use blue tooth to get it to start charging and the charger does not reboot. It is as if the integration is somehow triggering a reboot of the charger when it is connected.

If I restart the charger, it is back again connecting to home assistant with the same things happening and losing connection after a minute or two.

Any ideas of what I can try next?

I've got this charger largely working with my C9. When adding the charger, enable 'Skip OCPP schema validation' and disable 'Automatic detection of OCPP Measurands'. If you don't do that, you get the constant restarts that you're experiencing.

When selecting the measurands, you can select all of them, the once that are not supported just don't show any data. So you can hide them later, or figure out which specific measurands you need.

Once added, I find it take sometime to connect and fill in the data into HA. You can try restart the charger, and initiate a charge, to speed it up.

The reason I say it largely works, is that it does sometimes go unavailable for short-period, and occasionally (+-1 a month) it doesn't come back online until I physically restart the charger. Its possible that its network related issue, but I think its more likely an issue with the charger itself.

Morning Many thanks for your response. I followed your recommendation below (Did it twice to make sure) and still have the same problem of the reconnect messages. (Currently on 150) I am running version 001238 of the firmware on the charger. I do have values pulling through to Home Assistant but in the last 48 hours, the Availability and Charge Control switches have been available for a a very brief period. They are greyed out most of the time. I did change the charge current with the slider and the log shows it as having been set. I also see a number of the following messages: Timestamp Config Response changed to 19 January 2026 at 03:40 04:41:49 - 3 hours ago

Hmm. Only thing I can suggest is to physically restart the charger, as in disconnect its power via the isolation switch, or the emergency disconnect. You can also try that, and completely uninstall OCPP, reboot, and reinstall. I've had the issues you mentioned, it was frustrating as hell, and doing what I mentioned above had helped me.

Mine is the same firmware as yours, I see they have a 1239 version out, but I haven't attempted an upgrade yet. (Goto ftp://anonymous:123@47.94.107.196:21/pub/ I believe its file 'LPC1778_Fw_OMD_1239_0106_TP-EVVA-W32ASS.evb'

This is how mine looks in HA. I still do get the occasional disconnect, but it doesn't impact my usage.
