I'd set the charge period in the spring, when that could be set from quick settings. I realized that I wouldn't be able to do that again, when the clocks changed back, but I saw where the mode schedule controls were and didn't see the point in setting the period to what it was, and left it till now. So I've set the forced charge time in the mode scheduler to 00:30 to 07:30, to match the night rate on Octopus' version of economy 7. However, the battery hasn't charged since.
Well, that's not quite correct. It did charge from 05:30 to 07:30 on the Sunday morning after I made the change on Saturday night. But It's not charged since. I have reset the system, shut down the battery, shut down the inverter, waited a minute or so till it all went dark, restarted the inverter, and restarted the battery. That was Yesterday [Wednesday] evening. What did happen immediately was that the system charged the battery, which had fallen to 10% charge, up to the SoC self use minimum of 15%. But, it's now passed 00:30 on Thursday and the battery is still not force charging. I don't recall looking before, but the system diagram on the dashboard is now showing the battery as offline, despite it did, briefly, get topped up immediately after the reset.
I'm sure I saw something somewhere about the battery will charge from the grid in force charge mode, if that is enabled, But I can't see where that feature can be enabled and disabled. I do realize that I should have done all this in the summer, when it would have be a much less expensive problem.
The inverter is identified in devices as H1, Model: AC1-5.0-E. The battery pack is Model: ECS4300. I don't seem to be able to locate a user manual for the ECS4300 battery, though I have one for the H1 AC1 inverter.
What is it I'm missing in getting it going?
The supplier says the H1's firmware is out of date and is updating it for me - I have seen it said I can do it, but I can't find where on the enduser account.
We shall probably see if that firmware update is a fix tonight.

I checked the video and went to the v2 app on my phone, but I don't have anything after the version numbers. So it looks like I don't have the capability to update.MaterialBarracuda48 wrote: ↑Thu Oct 29, 2026 4:33 pmCheck this video from Will here https://www.youtube.com/watch?v=dJ4jQ_zyako usually 10-15mins to update.

I must have got it wrong. The supplier's engineer says they've updated the other 2 inverters not the H1, which is fully up-to-date. That's made no difference, and it would not charge the batties again last night.
It seems odd to me that I can schedule forced charge in the day, and it works. I have done that twice now, just to see. But if I have a forced charge scheduled in the early morning, e.g. 00:30 to 07:30, the mobile app says it's in forced charge mode between those times, but the battery is idle, and there's no charging. It's of no value if I can only charge the battery when it's at day rate, not night rate.
The engineer says he's passed it to Fox, and they should be able to fix it over the weekend. I certainly hope they do.
Graham Fountain
Hopefully Fox can sort it.
If not I notice that the energy stats app still shows the old battery charge from grid options.
I don't know if it still works given that Fox emphasis has switched to mode scheduler, but it might be worth a try.

Energy stats app?

While there seems to be no chance, with a simple enduser account, of going anywhere with the energy stats app, I went back to V1 of the browser interface. That also has the old battery charge from grid option. But it doesn't work at all, other than to disable the scheduler in V2. I've been back and checked that V2 is still working during the day, and it is. What will happen tonight is now the question.

Thanks for that MB48. I knew I'd seen a guide to the new API system somewhere, but couldn't think where.MaterialBarracuda48 wrote: ↑Sat Oct 31, 2026 9:38 am

The battery charged properly this morning. However, I'd been in V1 of the browser app, having discovered that logging in there demands the user name, not the email address, as V2 will take.
I went there because I knew that would also have the old battery charge from grid option. Setting the forced charge period from V1 didn't work at all, even in the daytime as V2 did, but it cleared the mode schedule in V2.
When I re-added the schedule from V2, I also set it up to charge from 23:45 to 07:30, to see when it would drop out. It didn't. But I don't know if that's an effect of the longer schedule, Fox having fixed it, or the mode schedule reset from playing in V1.
So I've set it all up as it should be, and will see what it does tonight. But I am happy to have a well charged battery for the first time in a week.

As I've never had an API key, as far as I know, does the warning that generating a new key will stop the old one working mean anything to me, or is it just from a bit of boilerplate in the code?MaterialBarracuda48 wrote: ↑Sat Oct 31, 2026 9:38 amTry this post to get API key, make sure to save it to a text file if you can.

Just a warning you can ignore, it applies to those with an existing key... as it will make that null and void.
Spaghetti in the code.
You are welcome, hope it helps you.
It charged this (Sunday) morning with the schedule set correctly, which I think must mean it's all fixed.
I'm still not certain whether Fox fixed it remotely, which is probably the case, or if there was some corruption left from the setting by the old method, that mucking about in V1 of the app cleared. I shall see if the installer has a report from Fox on Monday.
Thanks for the help and advice, but I think I shall now leave it all alone, at least till the early summer, when I want to look at changing the forced charge target SoC to reduce export.
I want to reduce export, if I can, partly because the how much less I get per kwh for export in the day and import over night has gone up - now 2.08p per kwh -, and partly in the hope of minimizing wear on the battery and maximizing its life. But I will need to experiment a bit to see if I can set a target SoC for a month ahead - I'm not setting it every night from the weather forecast, and I'm not bothering to try and automate the process; I don't think it's worth the effort.

Although it charged on Saturday and Sunday morning, it's not started charging on Monday morning.
I begin to despair.

Monday failing after two good days points away from a permanent fix and more toward something intermittent — possibly the schedule not being picked up cleanly after the inverter's own state changes. Before touching the target SoC, I'd re-check whether the forced-charge window shows as active on Monday morning and whether the battery is actually below your set threshold when it starts. If it only works some mornings, that pattern matters, since a remote fix should hold. The installer report will be worth chasing.
