Years ago I started building RF devices to measure temperatures and switching lights on or off. I even wrote a small book (in Dutch) about my findings and experiments. But I always wanted to overcome the main disadvantage of RF devices: no feedback about the status of the lights. I thought that could be done better and with the introduction of the small ESP8266 WiFi enabled processors it could! But SONOFF beat me with there WiFi enabled switches. One disadvantage of the SONOFF devices is the poor software. To make the switches usable you have to upload third party firmware and install a Home-Automation solution on an other computer to control the switches. Another disadvantage of the SONOFF switches is .. well they are switches (Switch On Off). So there is room for improvement!
Albeit: I introduce to you: DONOFF (Dimmer On Off)!
