sensor.goveetemp_bt_hci VS XiaomiGateway3

For those who are interested, the Passive BLE monitor Home Assistant integration supports quite a few thermometers. The Govee support is based on a component I wrote, Home-Is-Where-You-Hang-Your-Hack/sensor.goveetemp_bt_hci/. If you are looking for just the decoder, check out Thrilleratplay/GoveeWatcher.

If you run Home Assistant, (or want to), the driver to pick these signals up, and get the values into Home Assistant, you will add this package: https://github.com/Home-Is-Where-You-Hang-Your-Hack/sensor.goveetemp_bt_hci

I'm running ubuntu 20 on a Raspberry Pi 4. I'm running Home Assistant in a docker container, instead of running their HassOS. I followed the instructions on github for installing HACS and the goveetemp sensor. I couldn't see the sensor showing up in Home Assistant. I chased a lot of stuff, including this bug report that makes it sound like bluetooth isn't all that reliable on the Raspberry Pi. I also found this thread in this subreddit, but that wasn't my problem.

I'm reading the bluetooth sensor with a raspberry also used for the webcam, found this library, reimplemented the parser in nodejs, this is the relevant part:

I'm going to make some tests with this library that I found that seems to support this device, I'll let you know if it works well !

Govee Temperature/Humidity BLE Home Assistant Component

Following the recommendation from u/flaquito and u/CorgiFinancial, and since I did not want to spend any additional time or money on getting new hardware, I ended up with the following. - Booted up my old laptop, which hasn't been used for 2 years, and set up the docker version of HASS. It was indeed very straightforward. In hindsight, I might redo the process and install either a VM or the supervised version, just so I can have the addons (seems like a cool thing to have). - Adding all WiFi-related things was super easy! TV, PS4, Chromecast, etc. For Yeelight, I had to enable "LAN Control" to all my lamps. - The Xiaomi Smart Home Hub is not offered by default on HASS. I found a custom integration on hacs.xyz (adding HACS integration was also straightforward). The custom Smart Home Hub can be found [here](https://github.com/AlexxIT/XiaomiGateway3). - Enabling the telnet mode was non-trivial for me, as I did not want to change the Mi server to China (seems it loses all current setup?). Note that most online guides tell you to swap over to China to get the "About" menu option so you can enable the telnet. Instead, I found [this](https://gist.github.com/zvldz/1bd6b21539f84339c218f9427e022709), which worked like a charm with the custom integration: first add the gateway using the Mi credentials (it reads the mappings and tokens from the Mi Cloud), then add the gateway *again* by selecting the direct IP + the above definition. You can then delete the cloud-based gateway.
