How to find MAC address

Hello! This isn't really an issue per se but wanted to add this in case it helps anyone else. The iOS app at least (not sure about Android) doesn't tell you the MAC address so here's how I found it.

From a terminal on the Pi where I'm running homebridge I ran hcitool lescan. and look for a line that looks something like "41:55:55:93:3A:79 FELLOW". That will be the MAC address you want to put into api.py.

With that setup the homebridge plugin is working, so thanks!

Not pulling data via bluetooth

I keep getting the following in the homebridge log:

[4/2/2023, 8:30:10 PM] [Kettle] calling getTargetHeatingCoolingStateCharacteristicHandler

Is there any way to confirm that the stagg-ekg-plus scrypt is connecting to the kettle via bluetooth? I put the mac address of the kettle into api.py.

Thank you! Would love to make this work.

State is always on – is this normal?

Hey there!

I have successfully installed your plugin – thank you for making it, it works great!

I just have one question – every time I go into control center/the home app activate the kettle, the kettle is reporting as 'on' (e.g. 'heating to 212°'). I then have to press the button to turn it 'off', and then again to turn it on (which then, will actually turn it on).

Is this normal? I also find that when I go to IPADDRESS:8000/state, that it is always displaying '1'.

Cheers!

After some time the API is not connected to the Stag EKG?

This seems to work for a short period of time but it loses connection. Is there something I am missing?
