Accurate/smart oil sensor? (discuss.tchncs.de)

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.

Get a Beckett Rocket and an RTL-SDR dongle. You can use rtl_433 to decode the chirps from the Rocket and do whatever you want with them. You keep the float, it screws into an unused port on the top of the tank.

I think this is exactly what I'm looking for! Have you used these in the past? I like that I can keep the float

My brother has a Rocket in his tank, it works great.

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.
