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.

I have oil heat too and I struggle to imagine how you would add a sensor to it. That tank is solid and thick, trying to get anything inside it is a horrible idea and trying to sense through the metal is going to be prone to problems. In the past I've just pointed a camera at the main gauge.

My tank came with a mounting point on the top of it where you can fit an ultrasonic sensor. You just configure it with the depth of your tank and that’s it. I have a unit inside that shows how much oil I have left.

Apparently, it uses an RF protocol that can be intercepted and interpreted in HA with the right dongle but I haven’t done that.

Edit: mine looks like this although with different branding.
