For a while now the connection with the brewblox server is lost sometimes.
When system is idling I can notice the error because all the sensors and valves show the red connection error symbol and I cannot give any commands.
When I give commands just when the connection is lost but not yet detected (no red connection lost symbols yet) the commands are queued and carried out when the connection is back again.
I think most of the times the connection is back within one minute.
When I check the devellopers tool in chrome I see these errors. One of these error for every command I gave during the connection error.
