Shelly
I use the vintage ones as they look nice.
I have 12 of them because my house wiring is 💩 so I can’t get smart switches to work properly
They’re wifi and can operate with the Shelly integration and / or MQTT. No need for an app, they have their own wifi when you first power them up to configure them.
The only reason I let them loose on the internet is to update their firmware, then I isolate them again.
I also have a pair of Lifx bulbs in the bedroom as they’re inside shades so it’s more about the RGB colour for sunrise / sunset than their visual appeal as a bulb.






I think you have enough people here stating their pfSense / OPNSense works fine, so I’d guess you have something unique with your setup - maybe it’s a dodgy cable, or you’re running both In & Out traffic over vlans on the same NIC on your PC and getting problems with unmanaged switches dealing with that…
I had an issue with my pfSense box not negotiating to 1Gb on a Cat6 cable to a switch. I tried all sorts of diagnostics and it turned out to be a problem with the wall socket crimping, so hardware issues do need to be checked… I’m obviously assuming you didn’t use the exact same cables as your firewalla…
Just some different angles to think about…
