Multi PV panel setups, Axle support and better self-serve sub management

admin

Big update - so big, we had to bump minor version number by 2! 😂

v0.7.1393 2026-08-11

Multi PV planes now supported
Forecast charts show each array in its own shade, so you can see what each one contributes
Axle support, add Axle token under Advanced settings
When an Axle export event starts, Wonder Watt exports for you automatically
Axle events beat everything else: Intelligent Octopus Go, Agile (and Wonder Batt) all stand aside, so nothing charges your battery while you're being paid to empty it
Self-serve on WW subscription page: turn auto-renewal off/on, update payment card, view your subscription history directly on Paddle
Fixed Solax sign-in issue
Addressed FoxEss midnight span - Wonder Watt now automatically splits schedules

admin So with Axle you just need to generate the token in Axle Settings and paste it into advanced Right?

and you don't actually need HA for this to work, daft question I know, I was just wondering how it picks up which areas are having a session and when. I like to know how things work just asking, let me know.

Really good work all of this, keeping WW pushing the boundary's

So say I have two Standard Export Schedules one from 20:10 to 20:40 and another Schedule 20:50 - to 21:20

Dave was saying (above) many of his Axle Events are on an evening from 20:00 to 21:00, So in my example if Axle scheduling was active in WW, and picked up the 20:00 to 21:00 Event schedule, would it Pause the 2 Standard schedules that partly cover that time frame of the Axle event? and would they be reactivated for the following day? 😃or is this a totally manual thing for conflicting schedules?

Simply because it’s connected to your Axle account and uses the same API that HA uses.

In normal operation Axle remotely executes and sends instructions to your inverter via the GE API to start and stop exporting on an event day. Does generating an Axle HA Token stop this remote control process so that WW or HA can take control and there are no conflicts?

Is WW sending info to Axle saying I'm in control here no need for the remote instructions today thank you? I did read the Axle HA Link on the advanced page but its not very clear to me at least how the remote control aspect works once a token has been generated.

Usually Axle announce events 24 hours or so before they happen, though I understand that they have also announced a short notice events option where notice can be as little as 2 hours. Can we expect a visible IOG style area in WW where upcoming schedules will be visible? This would be very useful indeed to be kept informed what WW is actually actioning and a check against the Event emails received from Axle.

This is a good question. I don't know.

All we do is export during that window, I guess the same mechanism that some are using Axle and discharge/manage schedules themselves, either via WW, HA or anything. How does Axle figure out what was exported in those cases?

Hmm - turns out they have access to your SMETS1/SMETS2 meter on your home registered MPAN.

Yes, we will build this out.

duplada

admin This is a good question. I don't know.

Is there any way you can find out from the Axle Developers please.? It could end up with a conflict otherwise, just being ultra cautious.

admin Yes, we will build this out

I look forward to that thank you.

So, I haven't got a compatible battery for Axle (Growatt), can i get a token for WW to run this for me?

daveharding100

Nice add on to WW. I have been using Axle (combined with GivEnergy Battery & Gen3 Inverter + Octopus Flux) for a couple of months and it works as sold:
• GE subscription paid for
• Axle pay via smart meter readings as promised

My only gripe is that when I get the 24hrs warning e-mail from Axle I need to disable the discharge events on WW and then remember to re-enable them. Typically I get _£3 for each 1 hour event (_£6 for the 2 hour eclipse event last night)…
…this is pretty easy to do and is just on the cusp of being worth the effort - I really want a 'set and forget' set up.

Can the process be automated?
- I have pasted the Axle token into my WW settings - I have the same question as above. I cannot see how I stop Axle requesting a discharge, so I assume that both WW and Axle will request a discharge? I will see how this works in practice at the next event!
- Many of the Axle events seem to be at 8pm or 9pm, ie after I have discharged the battery for the Octopus 4pm to 7pm 29p/kWh peak rate discharge. Obviously £1/kWh from Axle is better so I would like to automatically cancel the scheduled export event when there is an Axle event on later the same day (perhaps another binary selector switch in the export logic).

Has anyone worked out how to stop Axle requesting a discharge (assuming that WW is now doing this) or does Axle somehow work this out as I have copied the token and WW is now linked to Axle?

@admin, could the "disable discharge if Axle event later today" feature be added to WW? I am not sure if this will help others not on Octopus Flux?

duplada

daveharding100 or does Axle somehow work this out as I have copied the token and WW is now linked to Axle?

That is exactly what I want to know, can you update us after your next event please?

It will be interesting to note what the Portal logs shows for Inverter commands sent and who is actually controlling what.

@admin may come through with the answer in due course, usually does.

admin

daveharding100 Well, I imagine it's the same for users who have HA that control it themselves.

Your Axle token is only used for receiving the events from the Axle API, that's it.

So unless Axle has some option for you to disable their control of your inverter, you will likely get duplicate discharge instructions.

Since Axle already support users controlling their own discharge I'd suggest it would make sense for them to make this option/toggle available in their customer dashboard. "Using 3rd party to trigger Axle charge instruction? You can toggle Axle instructions off here." or such, somewhere, with more brevity. 😂

Worth for you chaps who are on Axle, to ask Axle.

Yes - this makes sense. We will refine this functionality as we learn more.

Did you save this? Make sure you Save settings at the bottom of the settings page after adding token.

I posed a question on the GE forum to a HA user using Axle. His answer with log screen captures can be found here

https://community.givenergy.cloud/d/7223-axle-vpp-and-solar-iboost/8

It would seem that Axle still does the controlling when using the Axle Token, therefore using the WW Axle feature will result in duplicate sets of commands being sent to the inverter from Axle and WW, which is not a good scenario.

Unless Axle put a toggle as @admin suggested on their user dashboards (which I don't think they will do) it's a no go as far as I can see. They do support you setting your own schedule, because I asked them, but only if the Automatic remote commands fail. They then read your export results from your smart meter.

admin

duplada I saw a screengrab somewhere (possibly in the Axle FB group) that looked like there was an option in Axle for full automation or "events only". I imagined that was pretty close to "we don't instruct your inverter"?

duplada

@admin I see, I don't have any social media accounts so I couldn't access that group. If Axle users here could comment on your discovery it would be useful. When I have sent Axle emails in the past they do reply but often their answers are short of the exact detail you require, or gloss over things which isn't helpful.

admin

duplada Something else worth noticing on the Axle HA page is:

https://vpp.axle.energy/landing/home-assistant

Specifically, the reference to "Events Only" mode. Surely that must mean Axle do not send instructions? And also notice how it mentions that the Home Assistant (and the token) is only available when the user enables Events Only mode.

OK - doesn't look like my interpretation was correct: https://axle-energy.frontkb.com/en/articles/10193346

A duplicate instruction may not be the end of the world.

duplada

admin I think we need @daveharding100 to tell us what happens when he next gets an event. It all seems very confusing to me.

duplada

admin A duplicate instruction may not be the end of the world.

I had a nightmare once when after a failed standard schedule on a parse error, I instigated a quick schedule to fill the gap. Then for some reason the original failed schedule kicked back in, (must have been a retry I misread) and I ended up with a right mess on the WW app home screen. The schedule duration times didn't match and I stupidly cancelled the quick schedule which made things even worse. The quick schedule cancel actually cancelled the retry schedule, and not the quick schedule and didn't reset the times on the WW home screen quick scheduler. So I ended up with no schedule running and no way to perform another quick schedule because no matter how many times you refreshed the page WW remained convinced that the Quick Export Schedule was still active. Since that day, I keep well away from more than one scheduler service active at a time, unless I know nothing is scheduled in the time frame I am acting upon.

No, but I have now, hopefully in the nick of time for this evening's event...
...thank you.

admin

daveharding100 I'm not sure that has persisted/saved for you...?

It's in the Advanced settings, under Axle VPP:

When you save, you should see the Axle events section show up in the navigation bar:

daveharding100

Hi @admin, I get an error when I save, telling me to reload the page and when I do that the token has gone.
I have checked that I can change other parameters (charge rate now 0.99, was 1.0). I am doing this on my phone - will have a go on my PC in about 30mins.

Any thoughts?

admin

daveharding100 ~~Can you drop us a line pls on labs@wonderwatt.com with the token and we can troubleshoot/debug this? Thanks!~~

Actually, don't worry, think we know what this is, fix on the way.

Edit: Should be fixed now in 0.7.1408.

daveharding100

admin e-mailed to you and just seen your edit and tried it - looks like it worked....
...however, the new Axle tab in Wonder Watt is not seeing the 8pm event later this evening.

...any thoughts? do I just need to be patient? (I have only waited about 90seconds so far

daveharding100

admin sorry, just checked again and the 8pm event is there - let's see what happens!

Many thanks for your help

Dave
