Multi Device Tutorial

The EPEver project supports multiple devices.

You can set up the multi devices without an extra cable or pc. Now the Wemos can do that, too.

You must set the device ID successively, like 1..2..3..4..

If you have more than one device, choose one that should have ID 1. You don't have to change anything for it. All EPEvers are delivered with the ID 1.

Connect then the second device alone to the ESP/Wemos.

Set the device ID with the following URL http://<ESP-IP>/set?devid=2

You'll get a message if the ID is set.

Then connect the next device alone to the Wemos and call the url again with the next ID number (http://<ESP-IP>/set?devid=3)

Repeat this until all your devices have unique successively set device ID´s.

Now you can connect all devices to the ESP/Wemos, connect every RS485 A+ and B+ with the others, and with the ESP/Wemos. If the EPEvers all have two RS485 ports, then simply connect from first to second to third, etc. with RJ45 cables.

At last, set in the settings of the ESP/Wemos the quantity of your devices.
