I had a switch module strategically placed in an IP68 box but that’s one of the units that kept reporting disconnects, so I have removed it… see how I go without it… Don’t know if some units are better than others for that task…
I’ll either re-do the IP68 boxes or an IP66 mains socket higher up on a wall half way with a repeater plugged in. Or I’ll try to Share Z-wave dongle over IP (USB over IP using ser2net / socat ) guide… I have a spare z-stick and Pi3… and the garage is networked…
Thanks.
