Has anyone tried to use the LinkNode R4 Wifi board using the ESP8266 chipset.
I’m looking to control it via Emoncms on my under floor heating with 1 channel to switch on the pump and the others to switch on the zones. It has HTTP control so I guess I can use the CURL widget or possibly MQTT if its enabled.
I love the Openenergy WiFi Relay I have, but the cost to get 3 channels is a little expense compared to this unit.
Thanks in advance.
