Review of SM309 Zigbee Dimmer Switch

Verified Buyer

They do the job I need them for, but are very expensive for what they are. ZigBee bulbs, even the pricey Hue ones are significantly cheaper.. If these were closer to the price of the bulbs, I would buy them instead if the bulbs. My only technical gripe is that the external switch contact is not volt-free, it needs 8-220 volts to operate which is awkward. I would much rather they were dry contacts.
