| - | Tasmota is firmware providing support for various devices attached to an ESP8266. It has both and HTTP (web) and MQTT interface. | ||
| - | |||
| - | It was primarily designed for SONOFF power switches but can be used with any device to give an MQTT enabled WIFI temperature monitor, for example. | ||
