If you don’t need the HDMI display, mouse and keyboard of a Pi at the remote location then Arduino would be enough.

-My newest Solar PV Disconnect and remote monitor uses an Esp12-e!

SolarPV WiFi (4) 20 amp Fused Disconnect with 8 channel volt/temp monitor

I sure need help with programming! -just the MCP3008 part Get a MCP3008 (SPI-bus A/D converter) talking with an Esp12-e (Esp8266), -and get the 8 A/D channel data reported to Cayenne. [image] This PC board is an integral part of a Solar Array Collector, called a DC Fused Disconnect. I’m adding Wifi control and 8 channel voltage & temperature monitoring It is intended to be mounted inside an 8" length of 3" PVC pipe, and properly mounted on a QO rated 120/240v 100amp Outdoor Load…
