Connection Issues

[ApoclypseBoy]

Hi Kellerza

I'm Having issues with the sensors not being available.

I installed the plugin and configured it on a Pi3b and home assistant core image from them.

The log shows that I'm connected successfully and I did get some output to the dashboard after setting up a card in lovalace.

Now the app just runs for a second or two once you start it ( You can see the cpu load ) and than just stops.

Please advise on what to do from here.

TIA

Difficult to say without any logs. Would need the logs from the addon at least, you get it in the supervisor.

Add a line with three backticks (```) before and after your logs to format it

EDIT: This issue was resolved. One of the CAT6 strands broke off in the cabinet :(

Kellerza,

I'm running your main HEAD from a docker container but seems to be experiencing comunication issues with the Sunsynk 8kW inverter. It seems as if the unit comms times out:

I've connected the pins 1 and 2 to a RS485 USB converter as per your wiring diagram to the RS485 port on the inverter (the BMS is connected to the CAN port).

Do you have any tips to debug this comms issue?

EDIT: This is the RS485 to USB converter that I am using: https://www.robotics.org.za/index.php?route=product/product&product_id=5947&search=rs48

Thanks

[kellerza]

Thanks for confirming @dirkackerman !

Just to confirm: you used the port labelled RS485 on your Sunsynk 8.8kW, with the same wiring I have on the main readme (Pin 1 - B, Pin 2 - A)

I like your referenced converter, since it has a GND pin as well. Did you connect GND? (might be pin3 from what I've seen)

[dirkackerman]

Yes, RS485 port on the Sunsynk 8.8kW inverter (1 in the image below, credit system32 from https://powerforum.co.za/). Using your recommended wiring standard T568A with pin 1 (green-white) to B, pin 2 (green) to A and pin 3 (orange-white) to ground.
