Add zhimi.heater.za2 and zhimi.heater.zb1 support

[2esq]

Hi I was wondering if this smart heater was implemented or not. When I run the command miiocli device --ip <ip address> --token <token> info (with my IP and token) I get this info:

Model: zhimi.heater.za2 Hardware version: esp32 Firmware version: 2.1.4

but I can't seem to send any command to the heater. I understand this device uses MIoT and it's still a in it's early days of development but is there a way to expose the heater to home assistant?

Thanks

The support for these devices is added in #625, you should be able to use miiocli heater to control the device. If that doesn't work, feel free to reopen this!

We don't track homeassistant implementations in this repository, the proper forum for homeassistant integration is homeassistant's community forums. Or maybe @syssi has a custom integration available (looks like the API is quite similar to some other devices :-)?

When I do miiocli heater --ip xx.x.x.xx --token 3b46e0dde8dxxxxxxxxxx45ee81b2c39 on I get: Powering on Error: {'code': -5001, 'message': 'command error'} Same thing for any other command.

What could be causing this?

[rytilahti]

Okay, that's clearly a bug so let's reopen this. That message is coming from the device, maybe this device uses different commands than the one in the implementation. Is any other command working?

Ping @bazuchan - do you have an idea?

Maybe get_prop vs get_properties ?

The supported devices

MODEL_HEATER_ZA1 = "zhimi.heater.za1"
MODEL_HEATER_MA1 = "zhimi.elecheater.ma1"

are miIO devices. The zhimi.heater.za2 is a mioT device. In short: The ZA2 isn't supported right now.

syssi, is there any way to control the heater, even with raw commands? I reckon in homebridge there is an integration already working. https://github.com/github9984/homebridge-smartmi-heater#readme

[rezmus]

@maskiopt use above specs and send raw commands like this

{"method":"set_properties","params":[{"did":"X","siid":2,"piid":2,"value":true}],"id":123} # turn on {"method":"get_properties","params":[{"did":"X","siid":2,"piid":6}],"id":123} # get target temperature

"did" may not be necessary (depends on device).

Model: zhimi.heater.zb1

dmytro@dell-7510:/mnt/d/Desktop$ miiocli heater --ip 192.168.0.XX --token ****** off
Powering off
Error: {'code': -5001, 'message': 'command error'}

[devpitx]

how can I help you to add it to the supported list?

[rezmus]

it's miot device, it won't work via miio class.

al-one/hass-xiaomi-miot supported zhimi.heater.ma3, Maybe you can try this component for HA.

[xztxy]

zhimi.heater.za2

al-one/hass-xiaomi-miot#12 (comment)

al-one/hass-xiaomi-miot supported zhimi.heater.ma3, Maybe you can try this component for HA.

[PRO-2684]

From this helpful link, I created heater_miot_za2.py based on heater_miot.py, which added zhimi.heater.za2 support. PR here. #1301

This can be now closed thanks to @PRO-2684 - please open a separate issue if the miiocli heatermiot is not working for other models.
