MyHomeKit BT connection #39

Closed zonradkuse closed 2 years ago

zonradkuse commented 2 years ago

Hi there!

I am currently playing around with openrowingmonitor and wanted to try out the BT connection using MyHomeKit. Unfortunately, I can't connect and I am not familiar with BLE and the FTMS protocols.

I am using a fresh install of openrowingmonitor as of today on a raspberry pi 3. The bluetooth device is discoverable as OpenRowingMonitor by my Pixel 5 in MyHomeKit.

I've got the following log from btmon:

Do you have any idea why this is happening and what I could try to fix this?

Cheers! Johannes

Hi Johannes,

if you are using the profile "FTMS Rower" in Open Rowing Monitor, then this implements parts of the BLE GATT protocol for the Fitness Machine Service 1.0 for Rowers. You can download those specs from https://www.bluetooth.com.

I'm not sure what MyHomeKit expects or what your exact usage scenario is. But I would assume that you either have to implement a custom connector in MyHomeKit for FTMS or you would have to implement a custom Bluetooth profile in Open Rowing Monitor that is supported by home automation systems.

I'm sorry for the typo. I meant MyHomeFit as it is mentioned in the README.md and OpenRowingMonitior is listed there as possible device to connect to.

Hi Johannes,

BLE connections from MyHomeFit to openrowingmonitor should now work - see https://github.com/laberning/openrowingmonitor/discussions/36

lovely! thank you so much! I'll close this and report back if I encounter any issues :)

laberning commented 2 years ago

Hihi all good, I was thinking you were planning some kind of MyHomeKit Home Automation Integration with your rowing machine 😄

zonradkuse commented 2 years ago

That could be funny -- to keep some smart light bulb on you have to row constantly. I might give that a try when I find the time and let you know! :D

laberning commented 2 years ago

Yes you are right 😄 I just created an idea on the board here: #43 so we don't forget about it. Still can not think of a use-case where this is really useful, but it for sure would make a rower with Open Rowing Monitor unique...
