6/10/2023 0 Comments Ti connect v1.61x Wemos D1 mini (Optional and limited supply).1x Assembled EPEVER RS485 to ESP8266 board.If you wish to print the case yourself the files are available at LinkĪvailable as assembled only currently due to SMD design Many EPEver solar charge controllers have an RS485 communication port on them so you can connect a PC or Android device and read it’s statistics or update the settings. If there is demand i can create another product which would support passthrough. With this change however you can no longer use socat or similar to connect to the device and it has to either be viewed via the web interface or data pushed directly to MQTT or influxDB. If you do have a more advanced setup however you can configure the device via the web interface to post the data direct to an MQTT or influxdb database. This fits nicely if you have a solar setup where you would not want to be running a raspberry pi or similar just to connect to the charge controller. The next major change is that another device is no longer required if all you wish to do is check how your solar is doing, check your historical statistics or even switch the load on and off. I will not be including a network cable as that is better sourced locally. I have taken the previous design utilising an RJ45 socket and expanded it so that it is now surface mount only and utilises the popular wemos D1 mini which allows easier flashing and connectivity as it has a usb port built in.
