Hi, it's possible to connect to Deye Inverter?

This is the inverter

Network to RS 485

Blue (line 4) to B and Blue/White (line 5) to A according to the document

USB found in home assistant

Update, look like the addon connected to inverter using line 1-2 to B-A and plug into BMS RS 485 instead of Meter RS 485

However there still error, please help.

Your connection now seems the same as we have documented on the main readme of this repo

can you try less sensors? (Only try 1 for now)

[tuanha2000vn]

Thank you, I've managed to connect to the inverter using Port Address instead of Port

PORT: /dev/ttyUSB0
PORT_ADDRESS: 192.168.1.120:502
SUNSYNK_ID: '21031292XX'
SENSORS:
  - battery_voltage
  - battery_soc
SENSOR_PREFIX: Sunsynk
TIMEOUT: 10
MQTT_HOST: core-mosquitto
MQTT_PORT: 1883
MQTT_USERNAME: xxxxxx
MQTT_PASSWORD: '111111'
DEBUG: 2

There a few MQTT sensor issue, need to restart to clear them all.

I'll report about the progress soon.

Thank for the amazing addon.

[kellerza]

Ok, glad you got it working, I’m assuming you are also using mbusd on the same host?

Yes. There a few issue here and there, I'll try to report them all

If I add a few more sensor, there's an error. Something like it can't cast none into str/int

If a sensor added then remove after restart, addon error because it can't unpublish it from mqtt and need to delete mqtt device and let it populate again

[tuanha2000vn]

Sometime all sensors became unvailable, maybe 1 of the sensor fail to read/convert to float/int cause the issue?

Maybe my network cable too long (15 meter) or the baurate can be set higher than 9600?

Anyway I got near instant sensor value update, that amazing.

[kellerza]

15 meter is not long, as long as your data lines are on a twister pair (like orange/orange-white)

Lower baud rate is also better for long distances, but in this case we have to match the inverter.

See the linked issue above for available

I’ll look into the filter, that should not happen

MQTT do unpublish sensors you remove, but also hardened this and will publish an update to the addon over the weekend

[kellerza]

Anyway I got near instant sensor value update, that amazing.

glad that is working :-)

a big part is the combination of reading often, and only publishing on changes with the filters

[kellerza]

The filter issue seems to be caused by sd_status or fault, which are both test fields. Try force their filters to last for now

- sd_status:last
- fault:last

[kellerza]

Text will now be accepted by the filters, so you should not need the filter overrides
