Bingo, the missing IDX number was the problem.

That cost me some time, thank you tozett for the hint.

Same problem here with DHT22 sensors.

I tried two different sensors with multiple boards type ESP-01 and ESP-12. The vallues are allways 0.00.
When i try it with LUA-code its working.

Any suggestions? I would really like to continue with ESPEASY.
