For Renogy Rover RS232/RS485 compatible WiFi module
I wanted a way I could monitor my Renogy Rover MPPT controller in my camper and save historical data using MQTT and InfluxDB on a Raspberry Pi Zero W. This RS232 WiFi adapter fit the bill for what I needed.
I wasn’t familiar with the Pi Pico W and Micropython and I struggled with a few things getting it set up and found some of the documentation to be a bit unclear, though I admit at times I missed seeing information by not reading it carefully.
I found the seller, super-responsive and helpful. I ran into an issue connecting it to the Pi Zero W due to not having it connected to the internet, thus not able to contact a time server needed for the PVOutput connection (which I’m not using). The seller modified the program to now be able to sync the time with the phone when setting up the RNG SyNC, allowing use without an internet connection. I just returned from an off-grid camping trip and everything worked flawlessly.
