    Raspberry Pi Bluetooth Monitor

    Sounds like you got the prometheus server installed, however, did you install the prometheus client? Check this folder here: /Volumes/pi/.local/lib/python3.9/site-packages And look for a prometheus-client folder. If not, you might need to do this command: pip install prometheus_client I...

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    I could look at adding support for other devices down the road, but difficult for me to test since I don't have one of those batteries! As for MQTT data output, that's possible. I've got a configuration and there are hooks for where to send the data. I wanted to make it easily extensible...

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    @SolarShed I never got the charge state to work with the solution from Olen/solar-monitor. Eventually, I took a look at the script mentioned earlier from cyrils/renogy-bt1, which grabs a lot more data than Olen's solution including the charge status. Cyrils' solution is much simpler and that...

    Raspberry Pi Bluetooth Monitor

    I've been trying to get a customized system working to monitor my Renogy Rover 40A charge controller using a Raspberry Pi and Grafana. I've had some success with other open source projects, but ultimately decided to take some of the best parts of other projects and customize them into a system...

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    I think I've finally had some success. Added some code to the datalogger.py to log to my prometheus setup and could pretty much re-import my original Grafana dashboard. Pretty overcast snowy day today. Haven't checked the panels so they might be partially covered with snow from the day's...

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    oh and just curious, are you running your install as a service? I'm curious how that would work (having to restart a couple times) as a service. I'd rather have it retry a few times, then alert me somehow that the service didn't start on a r-pi reboot.

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    Oh SNAP! You weren't kidding. I've been starting it at random intervals all day, but never really several times in a row. Now it's outputting data! I guess I know what I'll be coding later this weekend. Thanks!

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    @oedo808 I've been trying to follow what you've been doing and have all of the components installed, but am only having limited success. I've modified datalogger.py slightly to use the JSON logger to just print the json objects to the console window. Once I get some output, I'll probably...

    Automatic Transfer Switches

    Hey Everyone: I've got a small system I put together more or less as an experiment to power some gear in my office and learn about setting up solar systems. It consists of 4x100W panels, Renogy 40A charge controller going into a 200Ah battery that's tied to a 2000W inverter. Pretty standard...

    Order of Disconnect

    I need to shut down my system for a few minutes to make some adjustments and am wondering what's the best order for disconnecting the system from the charge controller? I'm assuming: Turn off inverter Disconnect the tray cables from the battery Disconnect PV cables from charge controller...

    Monitoring Renogy Charge Controller over Serial Port Broken!

    Checked and double checked everything. 5.6V from TX->RX and TX->GRND. But still seeing a different error now: At this point the RJ-11 cable is plugged directly into the GPIO. Not sure what I'm doing wrong.

    Monitoring Renogy Charge Controller over Serial Port Broken!

    Thanks for replying. These are all really good suggestions. I have reconnected the bluetooth module and it communicates with the Rover without problems, so I'm fairly certain the serial port on the Rover is fine. It just has to be something in the chain of cables/adapters. I'm going to try...

    Monitoring Renogy Charge Controller over Serial Port Broken!

    Hello! I recently set up a system with 4x100W panels into a Renogy Rover 40A charge controller. Coupled with a 200Ah battery and 1000W inverter. The whole system works great. The kit I purchased included the Renogy BT-1 bluetooth module for monitoring through their apps. But I wasn't happy...

    Renogy Devices and Raspberry Pi - bluetooth/WiFi

    I haven't seen anything that scrapes the bluetooth. And depending on their implementation, it might be hard to get a 3rd party app to connect to it due to security considerations. I thought about the same thing and I'm a software engineer by trade, but I don't know anything about bluetooth and...

    Renogy 1000W Inverter Serial Port?

    My Renogy 1000W inverter has an RJ-11 port for a remote on/off switch. The port looks very similar to the data port on the Renogy Charge Controller, which I was using to connect to a Raspberry Pi and run Solar Shed. I'm curious to know if anyone has discovered whether the RJ-11 on the 1000W...
