EpEver Solar Monitor

Monitor your EpEver Solar Charger via MQTT using this PCB and the following components:

- Wemos D1 mini

- MAX485

- RJ45 Female Connector

- 6K7 Resistor

- Jumpers (To enable wake up after sleep)

Flash the firmware from this repo. I also got all my information from to build this PCB:

Adjust your setting and it should send all data over MQTT.

NodeRed receives the MQTT and routs the data to a InfluxDB database. Grafana reads the InflusDB and visualizes the data just beautifully :)

"Wake Up" jumper needs to be connected to be able to wake up drom deep sleep

"Debug Mode" Jumper to enable debug-mode. this sets the sleep duration to only 10 seconds

some datasheets list different pinouts for the RJ45 jack! swap A<->B if connection fails. Check voltage-level and -polarity before connecting!
