Anybody Connected their ZS EV to Home Assistant

I have it also.

It gives you all of the info from the app and then some.

Climate temperature vs commanded temperature
Added range in last charge
12V battery, voltage
Bonnet closed status
Boot status (Including unlocking boot from HA)
Charging enable / disable
Charging current limit
Charging duration
Charging gun connected status
Charging power
Charging status
Charging voltage
Dipped beam status
4 doors open/closed status
Expected range
Engine status
Exterior temperature
HVAC Status
Instant power
Interior temperature
Last powered off
Lock status
Main beam status
Mileage
Mileage driven since last charge
Power mode
Power used since last charge
Remaining charging time
Side light status
Current speed
SoT
Target SoT
Tyre pressure for each tyre
Window open status for all 4 windows

Post in thread 'API integration'

I had a go at getting this integration installed and with a fair bit of help from the good people on the HA user forums* I have it running.

Working on some dashboards, but the nice thing with this is I can have a dashboard operating on both my and my wife's phone whereas iSmart is limited to one device at a time. Indeed there may never be a need for iSmart.

Will use something like this for a phone dashboard:

We don't need defrosting, so left those control out. I can still get them via the main dashboard if ever needed.

Some prettying up with a pic of the car etc might be...

It's for whatever you want to use it for. I use it for tracking info on the car, and occasionally have used it with some automations regarding charging (mainly as load dump in my last home as I had to carefully management peak current draw).

Here's an example of a couple of charts where I track economy over time:

Guess when I did a bunch of towing?

I prefer for charging automation to be managed by an independent charger control though, as I think it's best not to be reliant on the car's connectivity and SAIC's servers for that task.

But for the most part you certainly could use it to manage charging. In fact I might just trial it tonight for my wife's car with the plug-in charger during the super off-peak period (mine will get charged with our wall charger).

You could do all sorts of things - e.g. if you were a regular commuter and needed to pre-warm the battery and cabin in winter on certain days of the week then you could automate that to happen at a certain time of day if the exterior temperature goes below a set threshold. Easy to set a toggle to turn the feature on/off.

Or set up an alert if the 12 V auxiliary battery voltage drops too low too often, indicating it might be good idea to tend to it or replace it.

I have a sensor I set up to tell me how many days it's been since the car was fully charged to 100%. I could set a trigger to remind me to do that if it's been a bit long.

Really it's a function of your imagination and thinking "wouldn't it be good if... ?".

Looking good.

To be honest i would not want to uninstall the ISmart app though, the connection to the servers via HA, seems even more dodgy than the app.

I have had literal days, where HA was not able to connect to the MG server and when i asked about it, i was just told, the error meant that MG servers were not accepting my token. 2 days later it worked again, so must be their servers being bad.

See post #5 above for the link to the discussion.

A Home Assistant add-on connects to the SAIC API, the same system as the iSmart app uses. If you are already using the SAIC iSmart app, then you can connect Home Assistant to it.

There are a couple of Home Assistant integrations which can do this, I'm using this one:
github.com

saic-home-assistant-addon/saic-python-mqtt-gateway at main · SAIC-iSmart-API/saic-home-assistant-addon

SAIC-iSmart-API repository for Home Assistant OS (HASS.IO) - SAIC-iSmart-API/saic-home-assistant-addon
github.com github.com

But see the link I referenced in post #5.

It appears setting the scheduled charging didn't work but that just could have been user error on my part.

I will try setting up a Home Assistant automation today instead.
 
OK, have set up an initial automation, at least for now. This will enabled charging during set windows (cheaper power) and disable it outside those windows if we are importing too much power from the grid.

It started charging at 10 AM as expected.

Using the HA integration, you will make another driver in the ISmart app so the integration essentially connects like it was another ISmart user
