[APP][PRO] Connect Solar Solax Inverter to Homey

Hi @Michal_Stranik ,

I was following up the discussion you had in December. I’m facing the same “issue”.

In the Solax app you have 2 values, PV and Inverter, with the difference being in the energy losses from the converter. So my example below, 2228W from the Panels and after converting the effective power is “only” 2122W (4-5% losses in the converter).

The PV value is not very interesting but as far as I can see this is the only value you can readout from Homey, I guess this has to be a mistake somehow because the Load Power and Solar Power give the same value where I expect Load Power to reflect the Inverter value given by Solax (2122).

If the Solar Today and Generation Total is with or without losses I don’t know because this is also only one value in Solax.

when are you going to implement this?

It’s there, check add devices for Solax app.

Yeah i see my battery in de solax device, but it is not visible in the energy tab…



Have you added it as battery as well ? (Add device → Solax → Solax Modbus Battery)

Battery is not connected via modbus, i use wifi dongle, and everything is setup via the api of solax. The local


api app for solax doesn’t work, tried everything, local api is closed.

The current solar power is not shown properly (both cloud and modbus). What could be the reason?


So?
Idk how it works with Solax specifically, but the SMA inverter app connects to my inverter with modbus per wifi on port 502

Found it, added the convertor via modbus instead of api, had to give in the ip adress of the wifi dongle, works, added modbus battery, works!

@Michal_Stranik: Great app! thx for creating and maintaining it!

As far as I can see power control has not been implemented in your app yet? Any chance it will be in the near future?

I would like to be able to disable PV production entirely when total energy prices (including taxes) become negative. In the Sloax app you can to this with ‘System ON/OFF’. I have seen other integrations with Solax controlling this parameter, but cannot seem to find it in the Homey app.

Hi everybody. I still cannot add the inverter to the Homey. I use the id token and Registration number.

9 days ago, the integration stopped getting new data. I created a report with id: 7ab498e6-3659-4c65-acd8-d49acf77c6e4
I restarted the app, but nothing changed. My last data are from 9 days ago

I also checked it with Solax Cloud and these data are from 5 months ago…

The Solax inverter app for Homey hasn’t been updated for the last 5 months.

You mean https://www.solaxcloud.com ? So then it’s not related to this Homey integration itself.

Hello Michael, I have same problem. Sometimes, communication will stop. I dont know why. Ping to dongle is perfect, cant figure why this happend. I agree with Sharkys, no update on app, no changes. After some time (couple of days) it is wokring again. With no changes in my net.

Ok, on Solax Cloud, it was really the registration number which changed after replacing the wifi dongle, this is now working.

But why i don’t get any values from Modbus anymore? There was no change… The IP has not changed and trying to unlock did not change it. Still no live data…
