Working perfectly so far as dumb switches. I don’t yet have the wherewithal to use as smart switches. We went for white faceplates with brass knobs. They look really classy.
Works well with HA, easy to setup and integrate.
The only smart dimmer on the UK market approved by my family (other than Lutron), excellent product and customer support
So far I’m impressed with Samotech I wanted a discrete smart dimmer solution that is “wife approved” and I think I’ve found it. It appears to be a “normal” dimmer but does extras. Plus having a neutral option wastes less energy and no faint flickering like some do.
Please note I installed these is Schneider Ultimate Screwless dimmer back plates so they match the rest of the house, the schneider knobs are slightly too large so I needed to put a peice of thin plastic on the flat to take up the slack.
But other than that integrated perfectly!
These modules are definitely the best product on the market, by a long way. The plates are a bit cheap looking and feeling, but they cost £1 so they are actually fantastic value! Any time someone asks for recommendations on reddit I always give the link to these.
I love those, I had 10 in the house I bought to replace shelly dimmer 2s. I have had them for a year and I’m now adding more, there have been no problems.
They are a little different than the ones I had, but no noticeable different in appearance.
I used a Berker s1 blanks , drilled a 10mm hole in them and 3d printed a little adapter so I could fit them with what was in the house before! love them , using them with Home assistant to control them.
recommend!
Working well with Zigbee2MQTT (with Sonoff ZBDongle-P) and Home Assistant. Found that some had to be paired very close to dongle, but others paired very quickly when power was supplied to the dimmers.
Excellent device. Works just as I had hoped.
