HA Yellow + CM5 - can I Bluetooth?

Hello, I have a Raspberry PI CM 5 installed on a HA Yellow. I’m not sure I even have a Bluetooth module or if so that it can detect BT advertising, which I’m trying to detect from my Samsung Galaxy S24.

On the phone, I have “Quick Share”, contacts only, turned on and I’ve tried to listening for the bluetooth_device_found event in the Dev Tools > Events page whilst turning BT on and off on my phone. This is yielding no results. (either on that page or in logs)

My goal is to simply detect my phone when I get close enough to my HA Yellow so I can turn some lights on. Basically home / not home. I don’t believe WIFI is an option with my router.

Id like some advice on troubleshooting, or if I need to, what hardware I should instead be using.

Using: HA Core 2025.2.0 and OS 14.2

Thanks!

I do not know the Compute Modules, so can’t help you there, but HA can use cheap USB BT sticks. Just get one of the better ones.
Also look into ESP Bluetooth Proxy, which increase the range and contact points, so you can make presence detection.

“Presence detection” with HA is probably something you should search on for more detection methods.

It seems that the yellow does not have Bluetooth…

I think it depends on the compute module.

You are right Wally :+1:
I looked at the specs from the Yellow since I assumed it had to be on the board and didn’t find anything there.

Even if it has BT, The Pi BT is really just for short range stuff, low power. Meant for mice and keyboards that are close by. It sucks for getting to a device 8 feet away.

Thank you for all the ideas! I have a spare BT USB dongle I’ll try.

Be aware that it might not be recognized.

ESPHomr FTW! Bluetooth Proxy.
