Sunsynk + Home Assistant

[SauRoNZA]

Hey, I am trying to replicate this but my installer provided a wireless dongle the plugs into the RS-485 serial port and so I want to connect to that. Has anyone done that? not quire sure as to what config I must use.

I have MQTT:

MQTT

Instructions on how to setup MQTT within Home Assistant.

www.home-assistant.io

and the sunsynk plugin from github:

GitHub - kellerza/sunsynk: Deye/Sunsynk Inverter Python library and Home Assistant OS Addon

Deye/Sunsynk Inverter Python library and Home Assistant OS Addon - kellerza/sunsynk

github.com

Scroll up.

You use the other port, the integration has nothing to do with the dongle.

Buy a cable from Solar Assistant.

The figures updating at different times is due to Sunsynk's server. To save themselves processing money they only update every now and then, different figures at different time.

The integration interfaces directly with the Inverter, has nothing to do with the cloud service.

Is there no way to use the existing wireless dongle?

Not the new one, no.

That's unfortunate. Thanks for the info.

Dont buy the cable from Solar Assistant. It is way overpriced. I bought a USB to RS485 Converter Cable from Micro Robotics for R100 and it works 100%.

I just hit the update button when I see it and never has a problem. Generally they are very small changes to add extra sensors and such.

As for question two I have no idea if that can be changed or what it is, may be worth asking the developer on the GitHub page.

I do note different sensors seem to update at less or more regular levels and the Grid Status one is much too slow to rely on for load shedding so I made a binary sensor based on the Grid Voltage instead.

Either way I’ve never seen it update in less than a minute. I suspect it only updates when values actually change in some cases.

Like right now my grid load updated 24 minutes ago and I suspect it’s because it’s been zero throughout.

My Battery load on the contrary is updating every minute or so.

How/where do you check the sensor update frequency? I dont think the update frequency in the history graphs is confirmation of this. I have tested automations linked to grid power (where the atomation triggers when grid power goes to zero, i.e loadshedding) where the automation triggers in a matter of seconds. Usually less than 5 seconds.

I don’t.

And yes while it updates very quickly sometimes I’ve also often found it being quite delayed.

some cool integrations added to Sunsynk, smart switch access imminent too.

Hi All.

Just installed a sunsynk inverter and it came with the new dongle which i see doesnt work with home assistant correct? I see the web interface on local is basic.


1. Do i use https://github.com/StephanJoubert/home_assistant_solarman/blob/main/README.md integration now or

2. Do i use https://github.com/kellerza/sunsynk with my inverter and home assistant?

If i understand correctly i must purchase a "USB to RS485" and then plug USB into the Pi and the other end into the RS485 port? I see the "USB to RS485" are all out of stock

Are there not other ways like plugging direct into the network switch?


Thanks in advance.

1. Only works with the old dongle.

2. Works cabled directly.

And no it doesn’t plug into Ethernet, it just uses RJ45 as an interface. It’s a serial connection.

Thank you for your reply.

So i will use option 2. Get a RJ45(RS485) to USB (the usb then plugs into my main Pi for home assistant im assuming?).

RS485 to usb seem to be in short supply.

Hi

How can one calculate daily energy consumption in kwh from a power reading in Watts in HA and then store these values to use in graphs or a database?

Convert it to kWh and just give it to the Energy Dashboard and it does it for you.

No need to get involved once you’ve got the sensor.

  - platform: integration
    source: sensor.geyser_power
    name: geyser_energy
    unit_prefix: k
    round: 2
    method: left

 

[leonb]

Im not following you. How do you convert the watt reading to kwh in HA?

 

[leonb]

Ok. Apologies. I see its in the code you posted. I will try that. Thanks.

You feed the sensor you have with Watts in the source and then create a new sensor that is now kWh.

Now you enter that sensor in Energy Dashboard and it does all the work for you.

I bought the following for home assistant and sunsynk with kellerza plug-in.

Which pins on the rj45 do i crimp?

Thanks

Hi. Did you have to wire to Rj45 ? If so , what colour where
