Having a neutral makes this switch more reliable than the Auora AOne Zigbee switches they are replacing.
Great product
Great switch, it is good that it somewhat follows the standard and fits with other faceplates as the one that comes with it is shiny.
Unfortunately the turn key is different diameter so one has to use the supplied knobb which feels nice, but obviously doesn’t match my faceplate.
Love these devices, I am putting them all round my home. Nothing else on the market. I would like a on/off switch version (at a cheaper price point).
The v2 Zigbee dimmer connected with my Hue Zigbee hub with no problems. Great that the size is smaller and supports more flexible wiring options!
Small niggles. I was hoping to fit two of these in an an existing dimmer switch using the existing front plate but the dimmers are fractionally too wide to fit, (potentially I could file the plate to adapt). Also the threaded mount that goes through the front plate is 1 or 2mm longer than on the v1 which prevents my existing knob from being able to be pushed. Fine with their own knob.
There are great. The only downside I can comment on is that the power monitoring features are providing garbage data. I suspect that’s something to do with running on no-neutral mode
straightforward to install, although I did need to add a deeper back box (35mm). Integrated immediately with Home Assistant and Z2M.
Generally the dimmers have so far performed as expected. One issue is the labelling on the metal plate on which the dimmers are mounted. Although the plate was drilled for two dimmers and had small holes to allow access to the Brightness and Reset buttons on each dimmer, the letters B and R appear to be stamped on the plate as if it were only mounting a single dimmer, so they did not correctly relate to the function accessible via the nearest small hole. This led to me inadvertently resetting the dimmer when I meant to set the brightness and vice versa. It would be better if either the letters B & R were stamped in positions appropriate to the dimmers actually mounted or omitted altogether.
