Give energy actions stopped working

Hufggfg

Hi all,

I’ve been using Wonder Watt for a couple of months now and it has been great. All my schedules or immediate charge/discharge actions working perfectly.

This week I had a second AIO installed. It was rather painful getting it all up and running (welcome to GivEnergy), but now appears to all be working fine. Of course, that all required the system to be recommissioned etc.

Wonder Watt is still able to connect fine, and show all the info, but any instruction from Wonder Watt no longer seems to do anything at all. Instructions in the GivEnergy app directly work fine.

I’ve tried revoking the API key, and adding a new one, but it made no difference. Any suggestions on what to try? Can Wonder Watt support have a look for me to see if you can see what’s going on?

WattID is extraneous-buyer

Thanks!

ETA - I should say, the WW activity log shows the instructions fine. It’s just not doing anything at the GivEnergy end…

Hufggfg Can you go to Settings and click Connect followed by Save and make sure that the Gateway serial number shows up there? That's likely the issue. Instructions need to be sent to the Gateway, so reconnect and Save should populate GW serial and use that.

Welcome to the Dual AIO club, Its a lonely world you have just entered from a GE support point of view anyway.

Just make sure that you use the full 4% to 100% range of your new dual system at least once a week, and all will be fine. Biggest problem with dual AIO's is SOC between them. Use them or you will suffer, I made that mistake I won't bore you with details.

If not already updated by your installer you need Firmware V13 for the Gateway (top tip switch on the bypass before updating the Gateway or your house power will go off on reboot, then revert after the update has completed) and also DO618/AO618 or later firmware installed on both AIO's. Once V13 is installed on the Gateway, get Support to set a hard Gateway limit of 80amps (the max the Gateway supports) Only GE support can do this. Once you have V13 Gateway firmware and the AIO 618 firmware installed you are all set for maximum performance These latest Gateway and AIO firmware pair work together and attempt to throttle the charge if you accidently overload it, and the firmware also has the very latest SOC tracking software for dual AIO's . Have fun.

Now that I have my AIO's working correctly (SOC wise) and with the relentless hard work of the guys at WW supporting this configuration. Dual AIO's with WW is a killer setup, capable of moving a staggering amount of kWh in my case with ease. I hope it works for your needs also.

Otherwise you will suffer big time with SOC issues between AIO's you need to be on V13 Gateway Firmware at

Apologies for the slow reply! Thanks for this. I think I was doing the connection, but then not actually pressing the save button. Oops! Thanks for your help.

However, I now seem to have another problem: I have the auto charge rate set on. I can see in the activity log that it says eg “charge rate of 32%”. However, it always seems to charge at 100%. Is it possible to have a look and see if you have any idea what’s going wrong? Or do I need to speak to GivEnergy?

Thank you!

Hufggfg The dual AIO Gateway does not seem to accept charge rate in absolute numbers, but needs percentages instead.

{
            "id": 267,
            "name": "Inverter Charge Power Percentage",
            "validation": "Value must be between 1 and 100",
            "validation_rules": [
                "between:1,100"
            ]
        },
        {
            "id": 268,
            "name": "Inverter Discharge Power Percentage",
            "validation": "Value must be between 1 and 100",
            "validation_rules": [
                "between:1,100"
            ]
        }

We will put a fix in.

Hufggfg

admin ah that’s interesting. Thanks so much for the fix.

Honestly the support and speed of fixes you guys do is deeply impressive! Let me know if you ever want anyone to beta test anything.

admin

Hufggfg this has now been implemented and rolled out. Dual AIO systems will now correctly use charge and discharge rate because we are sending percentages through.

Hufggfg

admin amazing, thanks!

While I have you, a question and a feature request (that are very related)

Question: When setting a schedule, there’s a toggle for discharge rate, with options of “discharge rate at 100%” or “use current discharge rate”… what does this do? What is the “current” discharge rate? Is there somewhere I can read up on the different controls?

Feature: it would be great to be able to set a percentage discharge rate for each schedule slot. I use the slots to discharge my battery at the end of the day. I’d love to be able to tune this to do it at a slightly slower rate as it’ll preserve battery life, rather than having to do it at full power.

Thanks again!

I agree its not very well explained you will find the settings In the advanced section. WW really needs to record Charge and Discharge rates for both the Battery and Inverter to be most useful, because changing the Rates in the advanced section messes up WW automatic adjusted time calculations. The 100% option in a schedule (OFF) for Charge / Discharge is exactly that 100% of whatever you system can achieve. Setting the option to On reads the rates you have set in the Advanced section of settings. That is how I understand it. I am really hoping this changes see here

Exactly totally agree

I had been giving this some thought also and was thinking of suggesting a drop down list in the scheduler with varying percentages rates (like the Quick charge / Discharge on the home page) that you could apply to each individual schedule or to be able to enter a percentage, but that I guess would require more code and error checking to implement and you have to think about all the 1000's of already saved users schedules you can't mess with those.

Yeah, totally doable, as long as you are aware that if you then put the kettle, airfryer and microwave on, you may well be pulling from the grid. 😃

Hufggfg

admin yep totally get it.

Of course, the awesome feature would be a kind of “force export x, but if house load is above that, also support it” kind of like having force discharge and eco mode on together.

My assumption is this isn’t something that’s possible for WW to achieve, as it would need changes on the GivEnergy side.

That would be really useful to me also

Hufggfg

duplada oh thanks for this, that’s awesome!

I know my installers had quite some pain updating firmware etc when installing everything. Do you know where can I check the versions I have? I assume somewhere in the cloud portal?

Thanks for all your tips, much appreciated! Maybe I’ll get the scheduling set so I do a full discharge of last bit every day 23:30-00:00, and then charge over 5 and a half hours… hmmm, I’ll do some thinking

duplada Hi duplada, silly question - how do i update the software on my two AiOs? The current software is shown to be D0.617-A0.617, and I think this bow needs to be D0618-A0.618.
Thanks,
Steve

Yes click on inverters you will have 3 items displayed scroll along to the firmware versions of each device. The latest firmware download complete package is at this link below, scroll down the page, under Batteries> AIO Complete > download

that has the the latest AO.619 firmware for the AIO's and the Gateway AO.13 Firmware contained in the zip file, along with dongle software etc everything you need. You could ask GE support to remote install these for you but getting to talk to anyone these days is hopeless.

@MrMessy will point you to his cheat sheet I use a modified one that discharges all the way down to 4% by 23:20

Then at 23:30 it all begins I run standard WW schedules Charge, Export, then Charge Again. first One charges to 85% the Second exports back to grid down to 22% then back up again to 92% Once a week to 100% to balance the batteries. At the same time I heat the Hot Water tank with an immersion for the morning and remote run the dishwasher. This all happens in the IOG 6 hours window 55kWh in 16.5kWh Export out. Once a month I charge the EV but that's a different set of schedules. I am limited by my DNO export limit of 9.5kWh but of course I can import at 12kWh.

Good luck and may the force be with you.

Hufggfg

duplada thanks. Very helpful.

I have an 18kW export limit, but don’t really see the need to use it.

TBH, I’m not so interested in cycling my batteries aggressively to maximise the import/export turnover. I just want to be able to discharge it each day down to 4% and charge up to 100%, and doing both relatively slowly to preserve the life of the batteries.

Wow that's a big one you could go for triple AIO's in fact you could start your own power station.

Apparently the trick with the LiFePO 4 cells that are in the GE AIO's is to use the full range and often. The battery maintenance regime for LiFePO 4 is somewhat different to that of other Lithium cells (look them up). Early adopters of the GE Dual AIO's including myself had all sorts of SOC issues, partly due to firmware and partly due to not using them correctly .

All good now though ☺️

Steve1 Hi duplada, silly question - how do i update the software on my two AiOs?

Hi Steve, In the first instance contact your installer or GE support who can remotely install updates on your system for you. All the required information for self install can be found at the links I posted above. Therefore, If you have never done this before, or are experiencing issues with your system, it may make things worse, so don't attempt it. GE Home Firmware updating yourself involves screwdrivers, usb devices, and patience, not to mention a rock solid WiFi connection, if you don't have Ethernet wiring and fixed IP addresses in place.

duplada Hi Duplada, just had the following from GE. They have requested confirmation if the 80Amp limit you suggest is for import (or export?).

Hi,

The system looks to be performing properly now the breakers are up yes.

Based on what that paragraph says, I am not entirely certain it means the import limit. The import limit limits the power that is pulled in from the grid. If say you are using 60A in the home already, and have the 80A limit set, then you set the AIOs to charge, the AIOs will not pull more than 20A so as to not exceed the limit.

It is currently set to a 100A limit which will have been put in by your installer when the system was commissioned. It may be worth querying more on the forum if it is the import that needs limiting, but if you definitely want the import limit to be set to 80A I can lower it.

I am starting the updates to 618 on the AIOs now.
