Stop pushing data to weather networks if comms fails

[markhiseman]

My wish is that when Meteohub detects that the connected weather station has stopped sending valid data, it also stops uploading that data to weather networks.

For example, my WMR100 stopped communicating with Meteohub over Christmas. Meteohub detected this but continued to upload invalid data to Weather Underground every 5 minutes until I spotted the problem 2 days later - that's a lot of invalid entries to delete! :S

Mark.
