A fully featured board based on ESP8266 and MAX31855 probe for managing temperature of electric ovens either by on-off or by pid control. The board supports 2 independent temperature probes and up to 2 relais for heating output. All the user operation is performed by a CGI web user interface provided by ESP8266 webserver and can be called by any standard html client like a webpage, a mobile or tablet app. An optional I2C/SPI/HMI display may be attached to the board by using any of the provided expansion headers or the optional SX1509 digital io extender.
