Review: Nice home automation item - They work well as described. I use it for on/off control and dimming for my outside lights. Connects well to your smartphone for manual control or automation.
Review: I would give 10 stars if possible - These are amazing! Literally any feature you could ever want are already included. This smart dimmer is really geared for makers and tinkerers and is obviously set up for being integrated into projects and other devices. I have it set up to control and dim a string of 10 LED under cabinet lights in my kitchen. It even has switch inputs that are completely configurable so you can retain physical controls. Their website even has Arduino integration tutorials! I love that it automatically calibrates the 0-100 brightness settings so you have a full usable range. It also tracks power usage! You can even have it ping webhooks! I had this set up and integrated with Google Home in minutes. Absolutely the best home automation purchase I've made in years of not ever.

*by A***R on January 22, 2025*

These are extremely small, simple wiring, easy setup, and they just works. I highly recommend these. I just eliminated 3 dimmers in my kitchen with these relays.
