Hi, 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…

No local access to the relays it would seem despite the IP address being available and all normal normal ports for http tried. Size as you can see is about 3 inches …

No longer available on Amazon UK - how many did you guys buy? !!! Simon

Only 2 were available and I had one…

Sold out! I’ve got one coming tomorrow. :slight_smile:

So tonight I have upload a test ESP8266 WEBserver and WifiAP which all works, so first step completed. I’m struggling to load the ZIP containing the 3ch relay example from Martin. I’m using Arduino 1.6.12 on windows with OpenEnergy USB link all working fine. Tried adding the zip as a sketchbook,…

Have you had a look at this: https://www.arduino.cc/en/Guide/Libraries It covers installation via the Library Manager as well as installing a library manually.

No problem with those now. So I have the ZIP file ‘ESP8266_Relay_Board-master’ with all its content etc and I want to now load this into Arduino and upload to my relay board. Its not a library file as it fails to find files it needs, so its a step I’m missing I guess. All other built in examples …

A little more learning and the piece I’m lacking is the sketch that pulls it all together. I was thinking that would be in the ZIP file but its not jumping out at me? Loaded many other built-in examples no problem so just one small step away… :hourglass_flowing_sand:

Hopefully a stupid question: Are you trying to upload the zip file or its contents to the Arduino IDE workspace? Have you opened the zip file and looked inside? Should you be uploading the contents?
