The BHonofre is a tiny wifi switch with 2 relays that is made to fit inside a switch box.  It is not UL listed, so in the US you are taking on some risk if you use it this way. One thing I love about it is they give you easy access to all the other GPIO pins on the wifi chip, so it is easy to connect other devices and sensors.  On this one I’m using 2 capacitive touch sensors, one PIR Motion Sensor and a Dallas Temperature sensor. The firmware it comes with is pretty good, and comes ready to use with MQTT and Home Assistant or your Smart Home hub of choice. Since I already installed one with the stock firmware, this time I decided to exchange the firmware for an ESPhome sketch.  The BHonofre is one of a new breed of tiny, dual relay, smart switches that includes the new Sonoff Mini, the Shelly 2.5 and some other lesser known brands. I expect we’ll be seeing more switches like this that easily allow you to make your existing “dumb” light switches more smarter.
