Works on Renogy Rover Li 40 amp charger controller

I have it working with an ESP32-WROOM-32D board and a Rover Li 40 amp SCC

Nice. I have to you have two Renogy Rover 40 and I will also try it out. You have code to have a ESP32 with Wi-Fi server running that can send data to MQTT sites or serve a webpage on a local network?

@amygrooters Would you kindly share the code and how did you do it on your Rover? I was trying too hard to make it work but no luck.

I like to know too!!

Hey guys I'm happy to share the code but I'm an Arduino beginner and only work on it in the winter when I'm snowed in, so it takes me a few weeks of working on it to get back to the point where I understand the code well again. I used the code to pull data from the Renogy Rover and pass it to a Grafana dashboard along with some Victron shunt data, so the Renogy code is mixed in with some other stuff now. I'll attach the code as a text file - don't really want to post it here as official code without taking some time to re-learn the code and make sure I have it working again as a stand-alone.

Okay here's the sketch I used the renogy code in - I used it to send data via MQTT to a Grafana dashboard. Sorry I can't answer any questions about it because it's been so long since I looked at any Arduino code. In a few months I'll be working on it again and can post a better stand alone version. Hope this works okay.

For anyone still interested in this, I forked this project and added a lot of stuff, including a custom PCB, a 3D printed case, and MQTT data sending. Also fixed some issues that came up in the code regarding negative controller temperature readings.
