1. ArduinootaArduino library to upload sketch over network to Arduino board with WiFi or Ethernet libraries
2. EthernetENCEthernet library for ENC28J60. This is a modern version of the UIPEthernet library. EthernetENC library is compatible with all Arduino architectures with Arduino SPI library with transactions support. Only include EthernetENC.h instead of Ethernet.h
4. RegulatorDIY Arduino consumption regulator build to use excess solar power for auxiliary 'summer' heating. The solar power data are retrieved over SunSpec Modbus TCP. IoT monitoring with Blynk and local Web server.
5. TelnetStreamArduino Stream implementation over Telnet for OTA logging and debugging
6. WiFiEspATArduino networking library. Standard Arduino WiFi networking API over ESP8266 or ESP32 AT commands.
