Also there may be a newer version out, 7.4.162 is the latest but I don't know if they are allowing the original UCK to run that.
If you do what @ChrisD. suggested then you’ll have all the coverage you’ll ever need. He posted pictures of his own install and it was extremely neat.Running a cable would be best, would agree with that. Unfortunately the garage is detached from the house, so wouldn’t be that easy. Although it might be possible to run a cable, as there is trunking already for the cables from the solar panels coming down the house to the inverter in the garage. Tbh, there only needs to be a slight improvement in coverage. It’s mostly so that the manufacturer of the inverter/batteries can remote in if there’s any issues. Apparently, that’s something that LuxPower (manufacturer of inverter) like solar installers to make available if possible. Only other reason would be for updates for my car and that’s infrequent (Ford’s SYNC 3). Extra coverage in the garden would be nice but not that essential.
Shame the PoE chime is not sold separately, the existing chime is EU plug only.
