ESP32 | Omniksol Solar PV to MQTT Gateway

Last year I have replaced the Soladin 600 inverter for one made by Omniksol. The Omniksol has the option to monitor it using a WiFi module and an online portal made by Omniksol. But if you manage to get a 602 series WiFi module there is the option to read the stats directly from the module on TCP port 8899. In real-time, that is without using the Omniksol online portal.

This works by sending it a magic message like {0x68, 0x02, 0x40, 0x30, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x16} but this has to be personalised to the inverters serial number.

So let’s take a class at the Hogwarts School of DCC Wizardry. I have made a video about DCC Packets. In this video, I’ll analyse the DCC packet stream using cheap USB logic analyser. And using the NMRA DCC standard will show that it truly is quite simple and life doesn’t have to be analog.
