HOBBYIST ONLY - If you want to roll your own and create your own interface via NodeRED, OpenHab, etc, then this is for you. This is the circuit board we use in every upgrade kit and controls all aspects of the ECC system, but you must provide the communications hardware and operator interface.

HOBBYIST KIT INCLUDES:

• Latest revision circuit board.
• Latest version of firmware installed on processor
• One external temperature probe (DS18B20)

Technical support for this item will be limited. Download and review the TECHNICAL manual for interfacing and control of this board.

You MUST have an understanding of electronics, computers, MQTT, wifi, etc.

KEY NOTES:

You must provide a wifi access point with an SSID of WaiterControl. The firmware on the circuit board is pre-programmed to look for that SSID only and will automatically log onto it.(See TECHNICAL manual for password)

You must provide an MQTT broker at IP address 192.168.50.10 on the WaiterControl network. The firmware is pre-programmed to connect to an MQTT broker at that IP address only.

Supply the front and rear temperatures to the circuit board via MQTT message, Assign source as "4".
