Thanks!
I have more information. There is a first arduino at garage posting data to emoncms every 5s. Door status, temperature, power, etc…
The second arduino, at home, is posting some data every 5s and is pulling the string every 0,5s from the emoncms. Do you think this could be the problem? I suposed that the information on emoncms is stable until it’s updated every 5s. For example if the first arduino post an 1, it is stable on emoncms until there is another update at 5s with a 0. The second arduino is geting 1, 1, 1, 1… every 0,5. Perhaps the problem is here as you suggested. I could try to update emoncms every 0,5s?
Why there is no data available, 1 or 0 it’s not ever there?
Here is the complete code of pulling arduino:
