Water tank gauge system with off the shelve sensor

Hardware

Hi all,

I’ve seen people building these systems with sensors and esp’s.
However I’ve seen completely built systems like this:

I guess that when intercepting the 433mhz signal and parsing the data out of it this might also be a very nice solution to work with.

Did anyone try this?

Reverse engineering the 433MHz signalling protocol (there is no standard) will be far more difficult than using an ESP and ESPHome.

Ok thanks!
