We heat our house with oil (grumble grumble grumble) but our float sensor is not a very accurate measure and it’s out of the way to actually see. Has anyone come across a sensor that works with HA and has been reliable? Bonus points for something that still has an “analog” view in case of problem
I’ve seen some sensors on Amazon but I’m skeptical of anything through there.
I have a similar setup but with an ultrasonic sensor instead of a float sensor. rtl_433 had support for the sensor, and I could get a good signal reception with an RTL-SDR and cheap 433MHz antenna. I can even pick up signals from a neighbours tank that is some distance away.
The Rocket is ultrasonic.
