Hi! I have a clean HA installation which I just setup using latest hassio on a rpi3. I’m trying to make it read my new Xiaomi Temperature and Humidity sensors v2 (this one https://www.aliexpress.com/item/4000434285871.html). I only enabled the samba add-on and added the following in my configuration.yaml.
When I restart hass.io I get the following errors:
TypeError: ord() expected a character, but string of length 15 found

Any ideas? I hear that rpi bluetooth reception isn’t great so I currently placed the sensors just next to the pi.
It doesn’t work. Nobody knows for now what’s the exact reason. I’ve tried different RPs but without luck. After couple of hours it just starts throwing polling errors. I’ve heard that a solution based on ESPHome (https://esphome.io/components/sensor/xiaomi_lywsdcgq.html) is much more stable and my plan is to try it.

this sounds really great! I will have a look at this and afterwards, I will give a shout if it was successful in my case, too. I also got 4 of them.
Can you give me an advise regarding HACS and this custom component? I am a bit careful regarding custom modules, because I am afraid of them breaking all my installation when I am upgrading my HomeAssistant version… Is it that “dangerous” I think about it?
