I would have expected the ID41 to be running software version 1.2, build 218.

Sounds as though you can see it and connect from a browser - so that is good.

Suggest using Meridian Device Manager on a PC to bring your ID41 up to the latest software version, 1.2, build 218, which I believe will be required for the ID41 to interwork with the Meridian Control App. As per earlier threads, this software upgrade can take some time and possibly take a couple of attempts to get it to take. The general advice was to use a PC hard wired to Ethernet rather than WiFi, I used WiFi for the PC with ID41 hard wired but it did take some time.
