Hi.
Thanks for this information.
Do you know which Modbus register/command should be executed in order to set Device ID?
Hi, Andrii.
Iām afraid that I donāt know the Modbus command to set the Device ID. I have not tried to sniff the RS-485 data, but it sounds like something that I should do when I get some spare time! I had seen a list of commands that someone else had posted.
Here is what I did so set the IDs on my 6 controllers. Make sure that only one controller is on the bus. If it is set to default, then the ID number will be ā1ā, the number one. You can change the ID to the number that you want using the Solar Station Monitor V1.95.
I just did a Google for āEPEVER Modbus RS-485 commandsā and received a lot of very interesting hits, but did not find the specific answer to your question.

Just received an email from Epever support
The commend to read the ID of the controller: F8 45 00 01 01 F8 89 BE
F8 45: function code
00 01: the number of the address
01: the number of the bit
F8: read the Device ID value
89 BE: CRC
ā
The commend to set the ID of the controller: F8 45 00 01 01 02 09 FD
F8 45: function code
00 01: the number of the address
01: the number of the bit
02: the sending data (ID)
09 FD: CRC
Thanks, Epever!!!

I am looking for an answer on this also. I have an Intel NUC with the usb to rs485 connection to a Tracer series and I would love to be able to check on this

I moved to a USB to rs485 it does work just change the front config part. Also the entire modbus integration changed so this file no long works in latest versions. Iāll upload a new version soon

Thank you so much
sorry for being total noob, but what do you mean by āfront config partā here?
Any chance for some help: so close 
As mentioned, have the USB-RS485 cable. You mentioned that now should work with your solution?
Hi Guys!!
I am also a proud owner of 2 ep-ever-chargers and have been following you and using your configs as guidelines.
until 2021.8.6
everything worked just fine, but now with 2021.9.5 some of my
sensors stopped working and while i was never able to write to the load-switch-coils at least i got all sensor values.
i was wondering what your experiences with the new release are.

The files you mention, is that on github?
A complete example for epever is at https://github.com/martgras/esphome/tree/testing/esphome/components/modbus_controller/examples/epever.
Btw The component has been merged into esphomes dev branch now.

Hi there, I am also looking to set this up. my raspberry pi with HA running it right next to my Epever charge controller. Could someone please show their yaml file for use with a usb to rs485 cable connect to the raspberry pi running HA? Would be supper grateful.

That worked for me with the EPEVER eBox-WIFI-01 WIFI in my local WIFI Network.
Thanks a lot!
Does that mean that a Wemos D1 with ESPhome will get me easier to the goal? could you explain the steps?
With the latest update some sensor values where not available any more

Thank you so much. Iāve been really struggling to convert my old HASS Epever config over to the new version because things like reverse_order were no longer available. Your example config made my new hass install finally work with my Epever.
that makes my day!

For anyone interested, hereās my modbus configuration for my 3 x Epever Charge Contollers:
- 2 x Epever 5415ANs, connected in serial, used to charge 98 x 36v lithium scooter batteries to power my house (862.4 Ah)
- 1 x Epever 1206AN connected to an Epever eBox Wifi unit that powers a Raspberry Pi3 IOT router on my roof.
Iāve only used the Load Switch Entity on my 1206AN so I could automate it to turn off if the IOT router uses too much power. Of course the 5415ANs donāt use Load because the inverter is connected directly to the batteies. The 36v - 220v Inverter is connected to a Sonoff POW2 so I can moitor power usage.
