This device is a mains powered (no wall wart!) circuit board that provides a web page and API to control two 10A, 240V relays.

This project originated when I wanted to control my pool lights from my home automation system. Since the connections for the lights were in an outdoor electrical box, I needed a way to connect to Wi-Fi even though the unit was inside a shielded enclosure. Also, I wanted to connect directly to the 120v available in the enclosure without having to have a plug in power transformer.

• You can plug it directly into main power without a wall wart transformer.
• You can use either the built in Wi-Fi antenna, or connect an external antenna (not included) for more range or to reach outside a shielding enclosure.
• Firmware is open source and can be updated / hacked either using onboard programming header or over the air.
• Onboard pushbuttons allow manual control and debugging.
• Built in support for MQTT makes home automation and IOT functions easy.
• Most configuration, status information, and control can be done via the self hosted web page.
• Full documentation available - see links at right.
