Since i’ve introduced the second fridge  into my BrewShed, I seem to have had nothing but trouble with the BrewPi’s !
My latest woes have been with what is normally my rock solid Black Pi system ! The beer sensor has started to disconnect 
I’ve tried two during my latest brew and both have disconnected at random intervals. The GreenPi  system also keeps disappearing  from the network…

I hink the newest  fridge addition is the most likely culprit and  might be in  need some extra  suppression …..

4 drop outs into idle mode

EDIT

Hey after posting on @BrewPi forum it looks like I found a Bug in the update temperature code
