Sensor Description

Polar H10/OH1

I would like to integrate the Polar H10 (strap ECG monitor) and OH1 (wrist based plethysmographic pulse monitor) into BLE monitor / Home Assistant. The BLE specification for these devices is above.

I have tried to capture data using the logger as described, but have not been successful. This is the output from a bluetooth scanning utility on my mac.

Managed to get a little more info:

I will have a look in a couple of days.

I had some time to look at the manufacture specific data

in hex, this is 07ff6b0033000038

07 = length ff = manufacturer specific data 6b00 = company id 33000038 = data

Next, I followed the link you gave, but they talk about GATT. GATT is telling us that you need to set up a connection to read the characteristics. This is not possible with BLE monitor, as we only passively listen to data, not reading after setting up a connection. You can try e.g. with ESPHome BLE client to make a connection and read the characteristics.

The above message is most likely just a message to say that it is online and needs a connection to further communicate. Unfortunately, this means that the device can't be added to BLE monitor
