addon-ssh VS ble_monitor

Install this SSH addon: https://github.com/hassio-addons/addon-ssh

Probably easier to use the SSH & Web addon since Terminal was depreciated. It should also be in the Supervisor tab where you found Terminal. It's the replacement for Terminal and does the same things.

get the community ssh & web terminal addon

You should be able to run a custom docker container via "SSH & Web Terminal" addon (https://github.com/hassio-addons/addon-ssh). You need to disable "protected mode" in the add-on settings and restart, though.

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.

However, I use some of their other (older?) BLE temp sensors, and for Home Assistant, you can use this driver for them: https://github.com/custom-components/ble_monitor

FWIW, if your HASS is running on a device (like a Raspberry Pi) that has Bluetooth, you might be able to get away with a custom component like https://github.com/custom-components/ble_monitor instead. Of course, if your setup is working for you already there isn't much incentive to change it.

https://github.com/custom-components/ble_monitor will work with govee

Once again, who knows better how to install it other than the guys who made it? No one , luckily for you, even being an Hacs integration (so not necessarily polished) the documentation seems very well written

Yes, there's an installable component with HACS : https://github.com/custom-components/ble_monitor It's working really well 👌
