I bought this new Xiaomi Heater and there was no component to integrate it into Home Assistant. So…
Based on others work, I kind of modified other components to make them work with this heater and I’m pleased to share it with you all 
Please note I’m not a developer and this was my first time around python.
Repo:
Thank you!
it’s working for heater.mc2
Trying this with a zhimi.heater.zb1, but errors in logs:

Any idea’s ?
What integration are you using?
I dont have that heater, but I can take a look at the integration.
Good Work Sérgio, i´m glad to see the Portuguese guys sharing
knowledge to world, thank you for your effort.
The error from above is from your custom_component (https://github.com/ee02217/homeassistant-mi-heater).
Also tried https://github.com/fineemb/Smartmi-smart-heater, but this gives a (somewhat) similar error.
Inside the HA config:
- platform: miheater
host: 192.168.1.141
token: !secret xiaomi_heater
name: heater1
Then that’s the problem 
My component is for another heater: zhimi.heater.mc2.
They have different controls.
You may want to try this other repo but I cant guarantee it works. I could try to create an integration for that one, but I dont have that model.

Hi @royen99, I have updated my code to also support zhimi.heater.zb1.
Please note that this is not tested as I dont have that heater.
Plus: my code is a bit spaghetti at the moment 
I’m not sure the updates will work because there is a did parameter that I believe is specific to my model, but would appreciate if you can try it.
That indeed seems to do a lot more
It does get the proper properties (on/off and the temperature setting), but setting them not.
Hi @royen99,
That is good news. I’ll try to fix it as well this afternoon.
It would be great if someone with more python knowledge could help as well, as I’m sure the code can be optimized.
Also, I found out that if connection to device is lost, it does not get it back. So I’ll need to see how to ensure it tries to connect the device again.
Hi @royen99,
I have updated the code. Please let me know if you can already set temperature and turn heater on and off
Seems to fully work indeed.
Both on/off and changing temperature!
Za2 is work too!
Thank you
Thank you very much for the feedback!
In the next couple days I’ll try to make device detection better. Currently it’s querying the device everything, I’ll try to use is as config so that the integration becomes faster.
Would also love to make this hacs compatible and with better documentation. Hehehe
Hi,
I have Za2 and it is not working, have you done any changes to the integration?
Sorry, I didn’t test this myself.
It is a test result shared by members of the Home Assistant community in Korea.
I’ve been informed by 2 people that it works without modification.(za2 model)
Thanks for the feedback.
Weird that I did not got it to work 
Hi Sergio_pt
Thanks for this integration work like a charm, but I will like to know how can I add the card that you have as an example in your GitHub page in my home assistant overview page?
Hi George,
This is my card:
- type: 'custom:simple-thermostat'
name: false

hvac:
another_mode: false

Please note that information related to power usage is coming from a smart plug…
I have now updated my card as below:
