Wifi370 error messages

pimatic-led-light is producing lots of errors for me:
error [pimatic-led-light]: [Error: write after end]
and
error [pimatic-led-light]: [Error: connection timeout]

Maybe connection handling in the "driver" needs to be refactored. Currently it establishes a new connection for each call. Might be better to go with a singleton pattern and reuse one connection.

[mwittig]

Agree, but synchronizing to a single connection can be tricky as it may introduce hidden "race conditions" caused depending on the ordering of events processed. I had to implement a single connection handling as part of pimatic-denon-avr as the AVR only accepts a single connection.

@mwittig yeah that is true
