A new generation solar controller is being tested. The esp8266 processor (ESP-12E module) connects to the Internet wirelessly (WiFi), controlled via a web browser from a computer or mobile phone.

I hope to have a working layout by the beginning of this season. Here are photos of the control interface and processor:
