Trying to setup mitemp_bt integration with Home Assistant Supervised on Ubuntu

Configuration
1

Have a home assistant supervised in ubuntu. Now trying to setup mitemp_bt integration and i’m completely lost. Where shoul i put --net=host
and what needs to be configured on the host?

2

If you run HassOS, you don’t have to do anything.
That option is given when starting the container (and I’m not actually sure it’s needed to access bluetooth, tbh).

I am running HassOS Supervised on top of Ubuntu. So it is a container.

4

Same. The supervisor handles the docker networking stuff.

5

Well i’ve enabled the debug for mitemp_bt.

On host os

~$ bluetoothctl
Agent registered
[CHG] Controller 00:1A:7D:DA:71:14 Pairable: yes
[LYWSD03MMC]# scan on
Discovery started
[CHG] Controller 00:1A:7D:DA:71:13 Discovering: yes
[NEW] Device A4:C1:38:94:96:1E LYWSD03MMC

And all i see in HA logs

    self.battery = int(ord(res_battery))
TypeError: ord() expected a character, but string of length 15 found

So maybe i should try to pass the USB device into the container? Still can’t find the docker-compose. And shall it go into HA or superviser docker?

There is likely some confusion. Your log suggest you have LYWSD03MMC (the square ones), while the integration only supports the LYWSDCGQ (the round ones). The LYWSD03MMC needs a decryption key with stock firmware.

See https://github.com/custom-components/ble_monitor for a custom component supporting those (and more).

Thanks! Will try it out and submit a PR for documetnatnion if that is the case so the docs would be more clear
