Migration from Pi 3B+ to Proxmox 8

Sorry if this is in the wrong place.

First off, I run a medium Proxmox cluster at home and want to get rid of the Pi’s I have running. Power isn’t the issue. DR is the issue. I had a power outage 2 weeks ago and the pi system did not come up right. The SD card failed. I restored and it is fine at the moment. Proxmox is on battery backup.

The question is that I have 4 Bluetooth Switchbot plugs distributed in one room. The pi is in that same room and it works just fine. How do I replace the bluetooth connection the pi is providing so that I can use them with proxmox?

I do have a Shelly Plus 1 dry contact relay in there, but have been completely unsuccessful in using the bluetooth on it to connect the 4 Switchbot AC plugs I have. Prior to trying I did not know about BLE, but now I know a little more than nothing about it.

I also have a Pi 4 8gig as a touch screen to give you the status of various sensor readings and control but it is located 20 feet away and there is a 1.5" sheet rock firewall between them and it does not see anything bluetooth when I reset a switchbot. I kinda want to keep them because I can move them anywhere to temporarily control things. I know I can reprogram them with ESPhome, but would like to just leave them how they are.

Thanks for the thoughts and idea’s!

Yeah, the Shellys unfortunately don’t allow for an active connection (which you need, to send data back and forth, not just listen to BT broadcasts). BT Proxies are an option, but they only allow for 3 simultaneous active BT connections (so you’d need two and not sure how well they’d divvy up the connections).

I know Switchbot has a hub, it might work well if all you need BT for in that area is for the Switchbot devices. I assume it can handle more than 3 at a time, since it’s their product (but I’ve never used it).
