V_WIND gives no device

Posted: Saturday 09 April 2016 9:35

Hello,
I am building a solar power weather station :http://forum.mysensors.org/topic/841/so ... er-station
It works like a charm, for only 1 thing, the wind speed won't show up in domoticz as a device.
I use S_WIND/V_WIND and in the serial logs from the weather station i can see sending wind speed and in the mysensors serial gateway i see comming in wind speed.
In the hardware page in Domoticz i can see all the sensors of my weather station, including wind speed, but in the devices list all the sensors are present but not the wind speed (i blowto the wind speed sensor to generate some values, and i see them sending)
So why is the windspeed device not showing in my devices list ?

Re: V_WIND gives no device

I built a similar device which shows up in Domoticz. Difference is that I also send V_DIRECTION from the same node. Domoticz is very creative in combining sensors (speed, direction & temp). I could well be that if there is no V_DIRECTION update the device is not shown/created.
You could try to send a dummy direction by sending a "0" with V_DIRECTION.

I managed to have the sensor created. (but have problems with the direction value which doesn't make sense).

If you need any examples, please tag me (@AWI) in the MySensors forum.

Hi AWI,
You're a life saver :D
That was the problem indeed.
Added gust and direction as dummy value's in the sketch and now it report's a device.
Thank you very much.
