Hi @Peter_Bittner,

I believe if the diameter of the pipe is big enough and the sensor is mounted absolutely horizontal it should work.

And thx for the donation 😘🍻

Seems it is working for him … [water tank level monitor TS FT002(2) - YouTube](https://www.youtube.com/watch?v=Z0NEoNHcoAY&t=4s)  
As he mentioned, it needs to be perfectly leveled.

Btw, is it really so sensitive ? 😉 When I saw sometimes it fluctuates between 100 and 101cm, I wasn’t expecting it actually is able to measure on several decimal places ? Is it a bug or feature ? 😉

No, the sensor and the app work with whole centimeters, no decimals. The decimals are a result from the way Homey stores the data in the Insights database because it averages data for long term storage.

Yes, I saw that video. I will work on getting it perfectly level.

Is it possible to get the App to show the water fill in litres rather than cubes metres?

I’m using m3 because I can then make use of a default watermeter that is available in Homey. Making a liters meter is extra work for me, and also doesn’t match with international standards how large volumes are measured.

By the way: just move the decimal point 3 places to the right in your mind, and m3 magically turn into liters 😉

Hmm, just 1st time happened values were not updated on Homey for 4 hours (the LCD was updated thought). It happened 1st time since I have installed it. Anyone else has got similar experience? Reboot didn’t help now after 4 hours it got updating again, without me doing anything…

That probably means temporary bad reception or interference. In the app logs you can see why the app is disregarding received data.

Wow, I didn’t know you included LOGs ! 😉 Pity though yesterday “no reception” time log is gone already (maybe due to the restart, not sure). Even the bad reception/temporary interference is strange - everything was/is located as it was… Anyway, I see plenty of errors but seems to be working just fine now. Attaching just part of logs, where even CRC checksum error occurred.

Just not sure if it would help, today after I just installed v6 rc4 and after I tried to restart app …diag. code **b8d12186-3837-425c-9d0a-c0617b8b094f** - currently hour without update. Hopefully it will be again temporary only. _update_ 30 min later and it’s working again…nothing new in the logs though

Btw, time seems to be shifted according to the reality about 2 hours.

In the ChangeLog is mentioned:

## App timezone now always UTC

In SDK v3 the default timezone ( `process.env.TZ` ) will always be set to `UTC` .

I am doing something wrong rain barrel is 93.5 high water reaches 82cm  
space between the sensor is 8cm, that for me too, the barrel is also max full but it still only indicates 63% full Zie pictures for info maybe you can. Help me

Minimum distance the sensor can detect reliably is around 40 cm. That is your issue. So place the sensor higher, or accept that you will not be able to see reliably if the barrel is more then half full.
