I use PRTG Network Monitor to manage and monitor all devices on my home network, including (you guessed it) the BlueSpray controller. I have been monitoring the controller since early Sept last year (2017), and have noticed that for many days, the controller will become un-responsive. Are there any known issues with the manner in which the controller responds to receiving an on-going series of ICMP (aka ping) messages ? While I don't have a trace file of the network communications, what I am basically doing is sending the controller an ICMP (echo request) message every 10 minutes, and reporting on the response.
