The log you posted has nothing to to with Domoticz. It's all pure MySensors. See https://www.mysensors.org/download/serial_api_15 Yes that is correct, but the question was also can you show the serial log :) Unfortunatly the Domoticz log does not show anything with "old" sketch. But luckely for me ...

I found a small example code here, with a bit of modification it works :mrgreen: https://www.domoticz.com/forum/viewtopic.php?f=42&t=6306&p=42867&hilit=wind#p42867 Well at leat I am seeing a windspeed sensor and it is receiving wind data :D I will modify the code a bit more and than I will upload it ...

Are you sure the node is sending data to the gateway? You should check this with the serial monitor. Post the results. ;) Here is the codebender serial data with the "LIGHT_LEVEL" Arduino code, here you can see that it is sending 11,4m/s in LUX. send: 4-4-0-0 s=255,c=0,t=17,pt=0,l=3,sg=0,st=ok:1.5 ...

Did you try to delete the node (and devices), restart Domoticz and then add it again? When I remove the node (when available from Light) after a restart it will not automaticly come back as a windmeter. The Domoticz log file show Arduino Sketch name and number from the windmeter but thats it than ...

Hi, I am building a wind speed sensor node, but I am having diffictulty's in getting it to work The sensor I am using has a 0 to 5V analog output for windspeeds from 0 to 32,4 m/s. So what I did right now is I took the lightsensor example code (Arduino) and changed the formula to give me the value ...
