Can I mount the panel sideways? It is replacing a panel in a space where it will only fit with a portrait orientation.
I tried it, and it appears to work fine.
@mike.superbrown - I don’t see a reason why it won’t work, like you found out. I might consider a strain relief (securing the wire bundle to the wall close to the Rachio) on the wires as they won’t be pulling straight down, but to the side.
