Has Anyone played around with HomeASSISTANT addon for the MG4 ???

[wattmatters]

What do the logs say?

If an EVSE is plugged into the car then yes it should enable you to do that.

There is a switch to start/stop charging and you can set the charging rate and scheduler as well:

Hi .. what is the entity name that use to control the charging schedule ?

Hi .. what is the entity name that use to control the charging schedule ?

There are three:

select.lsjwhXXXX_scheduled_charging_mode
text.lsjwhXXXX_scheduled_charging_start
text.lsjwhXXX_scheduled_charging_end

The "XXXX" is my car's ID.

I don't however use them as I control charging with my wall charger.

 

[ari197]

So .. I think I have it working the way I want it to work .. I don't use the scheduling from the car, but instead I just turn it off and turn it on when the logic I created says it's time to charge (or to stop charging) ..
I have a dynamic energy contract - so the electricity price changes every hour and the 'cheap tariff' doesn't come at the same time every day .. by creating an automation rule, I don't have to think anymore .. just plugged-in the cable and let the HA automation logic works ..

questions .. what do you guys have for the intervals value ?

What do you mean by "intervals value"?

Turn what off and on?
And which home assistant system are you using?
MG / SAIC - Custom Integration or the SAIC MQTT Gateway (Python) addon?

turning charging on and off ..

I'm using the MG/SAIC - Custom Integration

I think @wattmatters uses the addon which is why he didn't understand your question about intervals.
I use that as well - it's more difficult to install but is more powerful than the custom integration.
So how do you turn charging on and off with the custom integration?

ah ok ... didn't realize there were 2 options ...

I use this action to turn on charging and there's another action to turn it off

I don't have those. I'm using the SAIC MQTT Gateway (Python) add-on.

Just started my car's charging with it, so no issues for me.

Hmm.. I just tried logging in with the app.. failed also..

Indeed I just added a second MG to my iSmart app and it auto populated in the Home Assistant MQTT after restarting the add-on.

hmm .. I wonder if we are connected to the same server .. I tried login with the iSmart app and it gave me "service unavailable" ..

try manually "curl https://gateway-mg-eu.soimt.com/api.app/v1/" also gives the same error ...

Just set up another Home Assistant phone dashboard for my wife to use. Only image I could find isn't really her specific model but it's close enough (same colour).

SAIC MQTT Gateway (Python) addon

I'm using this one.

at the moment I'm using the HA add-on integration .. I want to try using the SAIC MQTT gateway ... I installed all the necessary python libs (at least it's not sending back error), but I also didn't get any response ... if I check the running process, it's not running ... this is how I run it, is it wrong ?
