Growatt, failed to set invertor schedule

stuorr23

Hi admin, any news on the api stabilisation at all please?

admin

stuorr23 Hi - looks like for a handful of users, the Growatt API returns an error response when we are trying to set the schedule.

See below:

It's been working fine for most though. Can you set a charging schedule OK via the portal?

stuorr23

If you mean via your smart charging portal then yes thats all set fine.

admin

stuorr23 Sorry, I meant through the Growatt dashboard portal.

And if your inverter shows up as offline, as you mentioned in another post, it sounds like that could be the root cause of the problem why we get the error response from Growatt because your inverter cannot be reached.

stuorr23

Yes i can do it fine from growatt side, the offline issue was due to home Internet which i have resolved

admin

stuorr23 What happens if you go to the Wonder Watt Settings page and click on Connect again?

admin

stuorr23 We do still see the same response from Growatt, a mixture of 'inv_set_failure' and 'inv_set_mix_lost' response messages.

Can you check that you can set different time settings (even just vary it for a minute or so) for Battery First via the Growatt portal/website and Save those settings? What message pops up when you do this?

Just to make sure you can save new settings.

stuorr23

The button changes colour for a short time and thats about it

admin

stuorr23 I have the suspicion your inverter serial is different to what was initially saved.

Did you connect and save settings yesterday? If so, enabling smart charging again should work from then on.

Let us know. 😀

stuorr23

No joy, i will go an double check it but nothing has changed since it was working a few weeks back.

stuorr23

As far as i can tell as its partially greyed out on your portal the serial number is correct

stuorr23

I am now seeing something seems to be disabling the charge from grid capacity. Is this something that your app is likely to do? Whislt i troubleshoot this how can i disconnect your services please

stuorr23 Hi - this might have been a one-off manual replay of a request whilst we were trying to troubleshoot the issue, with settings not being written to your inverter.

Our apologies for the inconvenience!

stuorr23

Ok thank you, please let me know when i should try and reconnect again

admin

stuorr23 Thanks - should be OK to reconnect and unpause. We have added more logging in terms of the inverter settings that we are writing/sending to the Growatt endpoint. This will allow us to hopefully work out why this issue keeps happening for you.

Version of the app/site should be 0.3.135

Thanks for bearing with us.

stuorr23

Ok thanks, i have activated everything again. Its a while since i signed up but i dont see any sort of confirmation when i select connect to the invertor still. I did a test run this evening but got the failed to set invertor schedule message again

stuorr23

I get a pop up to say successfully. I noticed just now that my charge stop % had changed from 100 down to 78. This isnt something i have changed.

admin

stuorr23 That was the the percentages setting for last night for your system - we attempted an API call earlier with those values, but got an error message back from the API.

{"msg":"inv_set_mix_lost","success":false}

However, it looks like despite it saying it success = false, it still was set?

admin

The only conclusion we can come to is that your inverter's connection to your Wifi is not stable enough and sometimes loses connection. Could this be a factor, do you think?
