So I changed mine and seems we are back in operations. I kept all original pieces in place, including âwhite textil/paper gridâ ? at the bottom of the sensor. Itâs important to keep the right polarity, from the forum @Friedhofsblond shared, itâs mentioned.

That trick worked for me - thank you 
, I was first getting the one from neighbor, later mine, so I just enabled back Not to ignore the ID. Just a pity logs do not help much when trying to catch the right one or even interpret/check the data being recorded, eg. out of range etc. Would be nice to see also measured data⌠maybe instead of âshifting payloadâ, it could be showing recorded data - just an idea.

The ultrasonic sensors should be cleaned once a year.
You have to do that with the Oilfox too.
New version 1.4.0 ready for testing: Wireless Tank Level Meter | Homey
- Repairing of device added.
This is especially for you @Sharkys ! After replacing batteries, you can now easily repair the device to match Homey with the new ID of the WTLM sensor. This is only needed if the âignore sensor IDâ was switched off in settings, and you have multiple WTLM devices in range of Homey.
