Mine work excellent. Loved the first one so much, I brought a second one. I do wish they came with their own mount, so you didn’t have to install it on a light switch.
So, for the second one, I 3d printed a little stand for it, and just stuck it on the side of the fridge, as that is the best location for a lightswitch without specific layout.
I love the hardware. Super reliable. Sorry you had issues. FYI I’m using a Sonoff 3.0 Zigbee USB dongle, in case that helps.
I have one dimmer paired via Philips Hue integration, and the second connected directly to HA.
Mine’s working again, I just use the blueprint and no other automation is required to make it work. I agree they’re a bit flakey on dimming, but 95% of time they turn on/off on click.
I ended up digging one of my old Phlips Hue lights out and just doing a direct connect. That’s the main thing I was trying to do anyway, keep someone from switching off my computer when they flip that wall switch. Gave up getting this to work with HASS and the Sonoff Zigbee stick (but didn’t try the blueprint, was just easier to use the Hue)
