Presence Detection via TPMS Sensors in Cars?

[reh8388]

I am playing with my SDR and can reliably pickup the TPMS sensors from my vehicles in the garage. Would it be possible to make a presence sensor variant that lets you put in 1-4 "IDs" to search for that would match a vehicle? I have attached an rtf_433 read out of the data I am referring to.

This is a bit more advanced than what this plugin is capable of, but should be achievable with a combination of node-red and HomeKit-bridged ( ie homebridge for node-red )

Geting this to work would require effort with node-red, and time spent googling and trying out various combinations to get it to work

something like this

1 - setup a mosquito mqtt server and node-red on your rpi
2 - install the node-red flow “HomeKit-bridged”, this allows you to create HomeKit devices in node-red
3 - setup rtl-433 to broadcast received messages via mqtt
4 - configure nodes in node-red to receive the mqtt messages, and process them as you indicated above ( a lot of googling and try and error here )
5 - setup your presence accessory in node-red/HomeKit-bridged

This was extremely simplified, but should be doable
