Multi Version - Direct serial interface #131

cakuhn · 2023-04-21T05:36:47Z

HI

On the latest version, installed this morning (Sunsynk Inverter Add-on (multi): Current version: 2023.04.20b-0.3.2 (Changelog)) I get the below errors as reported in the log. The application then crash. Any ideas on a possible fix and the reason for these?

Thanks

@cakuhn can you try these options?

pymodbus - Using the device selected in DEBUG_DEVICE (at the bottom of the settings)
```
DRIVER: pymodbus
INVERTERS:
  - PORT: ""
```

Direct Serial + pymodbus

DRIVER: pymodbus
INVERTERS:
  - PORT: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A9007CPR-if00-port0

Direct serial + umodbus

DRIVER: umodbus
INVERTERS:
  - PORT: serial:///dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A9007CPR-if00-port0

umodbus via mbusd (and mbusd to serial)
This will work, but won't help me to test the serial implementation.

I had the exact same issue after migrating to the new release. I am glad I came across this thread as, touch wood, Direct Serial + pymodbus seemed to have resolved it. I am using a RS485 to usb converter direct to my HA server.

There was a thread on powerforum with a user with the same issue, I will link them here for resolution. Update: See you already responded there.

PS. thanks for your work on this addon!

hakonnissen · 2023-05-01T15:07:30Z

Same failure on my side since upgrading to HassOS 10.1. I've tried all 3 methods above to no avail.

When using Direct Serial + pymodbus I get no errors, but also no sensors available:

When using Direct serial + umodbus I get similar error as above:

Any help would be appreciated. Thnx

This is good. You either have no sensors in the addon config, or no auto-discovery enabled in HA

hakonnissen · 2023-05-01T18:44:57Z

Thnx for responding. I definitely haven't turned off auto-discovery in HA and my addon config lists the following sensors:

total_pv_energy
total_battery_charge
total_battery_discharge
total_grid_export
total_grid_import
battery_soc
However on starting the addon with pymodbus, show me:
2023-05-01 20:30:08,423 INFO Filter *last used for battery_soc, total_battery_charge, total_battery_discharge, total_grid_export, total_grid_import, total_pv_energy

I'm not a complete newb, but I must admit, this has had me pulling my hair out the last week! Any help would be appreciated. Thnx

Thanks so much, This one worked for me "pymodbus - Using the device selected in DEBUG_DEVICE (at the bottom of the settings)".

All time out errors experienced on the original version is also gone now. Using the NOW sensors, it also updates almost instantly by the second. AWESOMENESS

Best to open your own issue, as the driver seems to only be one of your problems. Please include all detail there including your mqtt server info

hakonnissen · 2023-05-02T15:06:15Z

Thnx guys. After much struggling, the problem was the connection to the MQTT server! Prior to HassOS 10.1, connecting to HA internal MQTT server on 127.0.0.1 was working fine, but fails for some reason in 10.1.
FINALLY working again. Thanks for a great addon!

in most cases core-mosquitto (the default) should work fine. 127.0.0.1 is not expected to work in standard Docker, as this points to the addon container itself

FINALLY working again. Thanks for a great addon!

I have a similar issue as reported at the opening of the issue. All pymodbus options give me the following error:

The umodbus options gives me the same error: 'Serial' object has no attribute 'host'

The cable should work as I have tested it with a SolarAssitant setup, however, that was on a Deye 5kw inverter. I'm trying to install this add-on on a Sunsynk 8kW,

mbusb does not seem to connect.

@kellerza Any ideas?

kellerza · 2023-08-18T07:10:11Z

Try the faul finding guide & make sure you plug it into the correct port - see the adaptors & wiring page. Maybe this is a newer model with a shared port?

https://kellerza.github.io/sunsynk/guide/fault-finding

NeillHerbst · 2023-08-18T08:16:41Z

I've tried both ports to test whether it is a combined port. I've also checked everything on the fault finding page.

As stated previously the cable wiring is definitely correct as it work on a previous SolarAssistant setup. Is there a way to check the port on the Inverter, i.e. that it is actually working.

kellerza · 2023-08-18T09:02:42Z

Try from your laptop with modbuspoll/modbus CLI

If still not working ~R100 will get you a different RS485 adaptor & run a short wire while standing next to the inverter.

Personally, I would just redo the wire since you changed the Inverter

Leecavturbo · 2023-09-03T10:14:20Z

Ok I preserved ( 11hrs solid lol ) .
I got a connection after entering the inverter serial number and changing port to “ “.
So the log went further than before but stopped at seemingly waiting for mqtt ? So I added mqtt broker and now it works except I’m missing some data like pv2 and total solar ( pv1+pv2 ). How can I add the sensor ?
also power flow card doesn’t show data.

@Leecavturbo nice!

The docs will show you that pv2_power is another sensor. There is no combined sensor for pv1+pv2 today, but you can build one with mysensors or a template (mysensors is probably more accurate)

If power flow card shows nothing you probably have incorrect entity names. Check these under devices/dev tools- state

You can use total PV energy sensor for the flow chart .
System do the calcul automatically and show only the day prod .

Yes kWh but the HA flow chart only use kWh or you talking about other flow chart? Le dim. 3 sept. 2023 à 17:23, Leecavturbo ***@***.***> a écrit :

SENSORS += MathSensor((186, 187), "PV power sum", WATT, factors=(1, 1))
That works for me, in case you wanna sum of pv1+pv2 in a single sensor
(see this for details, it requires a some hand work)

Wouldn’t even know where to start and I’ve never seen pv2 (187) as a sensor so suspect more work before your math sensor 👍

kellerza · 2023-09-16T08:45:42Z

I've been wondering if I should not simply add an all group? (especially for people not reading the docs 😉)

pv2_power is now part of the defaults just to show people you can add other sensors. here - do we need to add more defaults?

Nice solution.

If you use the power flow card you can also visualize two separate sensors and see the total in the UI -

got samba working and established i can create the .py from windows as notepad save as > in the share/hass-addon . but the code from 'here' link doesn't give your example. just add text below to the code ?

Leecavturbo · 2023-09-18T13:34:48Z

to update pv1 +pv2 sum is now working with SS add-on. Sensor = pv lowercase.

Leecavturbo · 2023-09-19T09:14:01Z

Anyone know what the sensor for UPS load is ? load_2 or output_2 eg ?

If you meant backup power output I guess you should read issues about all that sensors ("essentials" is a load on backup output):

Hallo good people.

With Direct Serial interface, how can I get two inverters to detect?
I have two SunSynk 8kW inverters in parallel as single phase, and when I can get read outs from each separately (the MQTT detects two devices) (ie. comms working) but not together.

Any ideas what I can do?
Thanks in advance!
