Hey HA community,
In my house I do have couple of analog gauges: measuring pressure in heating system, overall water pressure, and abit ancient gas heater which is not “smart”.
Quite often I’m not there, but supervision is required for the heating system.
It also had problem with heating system pressure, which if goes down may cause critical failure in heater and in pumps.
I did the monitoring manually, through IP camera, and then got an idea to automate analog gauges readings into the sensors of HA.
So thats my draft:
Its very raw, but works for me.
This is how my gauges looks like:
And this is needle recognition with value conversion:
Any interest, comments - welcome.
