RTL_433
Posted: Wednesday 27 August 2025 7:51
Hello everyone,
I have tried using RTL_433 with a popular (and cheap
) OEM weather station: Sainlogic FT0300.
RTL_433 is retrieving all the necessary sensors data (Temp, Humidity, Wind speed and direction, rain, UV and Light) with the latest version of the tool.
Unfortunately, Domoticz is not able to retrieve the UV value.
It seems that the code is not consistent.
Here is how RTL_433 is sending back information in
And here is how Domoticz is parsing it in
Obviously, when it refers to UV Index, these two guys are not talking the same language
On my side, I have fixed it by adjusting the rtl_433 source on my device (I know, it's bad). But the best way is probably to adjust it on Domoticz side.
Have a good day,
QQ.
