Despair with Homey trial, TrueNas self hosted nothing works well!

Playing with Homey to see if I have any interest in paying for it. If I was to continue I would have paid the subscription to keep i ton TrueNas and bought one or more bridge units. BUT Other than Sonos and Ring I have been unable to detect any of my TP-Link, Sonoff or other devices. I have them on Ewelink but the Homey app can’t see them.

I set up a flow to sound my Ring doorbell on multiple Sonos speakers, so I can hear it in the workshop as well as the house, tested it twice, was impressed, then next day it didn’t work at all, luckily I had not disabled the reliable Alexa system.

Reading the forums it seems that it this is a flakey product with an apparently easy front end.

Before I give up and never look back, does anyone have any advice that may make me continue and possibly spend money on Homey?

Sounds typical for either a double NAT or an incorrect VLAN (isolated/“guest”/“IoT network”) setup.
