kWh Meter firmware 5.00xx has been released as beta

[DCSBL]

Good news: version 5.0005 for the HomeWizard kWh Meter is now available. This update adds support for the v2 API and makes it possible to control the Plug-In Battery.

The previous version worked well, but needed some attention to meet our new quality standards. Over the past months, my colleagues rewrote most of the code from the ground up to support new features and improve overall quality.

New in kWh Meter 5.0005

• Support for the v2 API. Full details can be found at https://api-documentation.homewizard.com.
• Control up to four HomeWizard Plug-In Batteries. This feature is ideal for users that can't use a P1 Meter.
  • ❗ Currently we only test this feature with a selected group of users. It is not yet possible to configure your kWh Meter to control the Plug-In Batteries. If you want to help testing, please send an e-mail to beta@homewizard.com.
• Major code rewrite for code-efficiency, testability and maintainability.

New in kWh Meter 5.0006

• Fixed an issue where one of the phases on a 3-phase meter was misconfigured. This resulted in missing voltage information and phase 2 measuring 0 watts. If your 3-phase kWh Meter has this issue after updating to 5.0006, please reach out to us.
• Fixed an issue related to the battery steering algorithm that caused some batteries to cycle between charging and discharing too quickly.

New in kWh Meter 5.0011

• We’ve discovered an issue where the app wasn’t recognising the model properly, resulting in an invalid image (HomeWizard or Eastron branded). This release fixes that.

How to install

The update will be installed automatically. To check if your device has the latest version, follow these instructions: https://helpdesk.homewizard.com/en/articles/9167578-how-do-i-check-if-i-have-the-latest-software-on-my-homewizard-product. Your device must be signed up for the beta channel.

Feedback

Share your feedback below in English or Dutch during the beta period.

Question on this. What if there are both a P1 and a kwh controlling battery? Is the state/mode known on both or does the P1 or kwh query the battery first and then provide feedback/reply on the query?

[DCSBL]

Good question. The intention is that only one device control the battery group. So you have to query that device.

[jtebbens]

In a perfect world yes, but pretty sure the advanced users that know they can query will (ab)use both. So maybe a lockout mechanism to only allow one of these?

[Mausy5043]

Which suggests that the battery should be in control. Or, let the user configure the controller (P1 or kWh or whatever) in the battery settings.

[DennisSteenvoorden]

I can confirm that the firmware for the Homewizard kWh meter with PiB is working. For now no issues.
The nom feature is working as expected. The net consumption graphics looks like the p1 meter graphics.

[jtebbens]

Yes upon pairing/adding a battery there is either a P1 available in the setup (like now in Netherlands). Or in the situation of Belgium the construction is expected to be a kwhmeter as the P1 is bound by Synergrid and is not allowed to be used as a controller for the battery.

[DennisSteenvoorden]

All assumptions. The procedure is given above by dcsbl. Please follow it.
I’m in the Netherlands. I entered the beta program for the kWh meter. Updated the kwh meter. Installed pib, controller was Found automaticly. And voila. Really plúg and play.

[ArnoutD]

I am part of the Beta but my false assumption was that it was remotely activated I switched my batteries to the kWh meter (Hoofdaansluting) now... all works, as Dennis says, the HA Battery group mode works. The P1 is now out of the loop

but the Remove your battery from your home re-add assign it yourselves (and it will automatically select the kWh meter) was missing

[DennisSteenvoorden]

When starting greenfield. There is nothing to remove. So documentation is correct. But nice addition.

[DennisSteenvoorden]

The HomeAssistant 2025.7 version also works with kWh meter version 5.0005 for additionals new homewizard features.
I can put the PiB in stand-by mode by HomeAssistant. Great. I really like this feature while charging my EV.

[DCSBL]

Version 5.0006 has been released. Please see the updated discussion description for more details.

[Mausy5043]

Is this going to be actively pushed to all kWh-meters (presumably in batches)? Or does the update require human intervention (=initiating upgrade)?

[Devke1972]

Look at the first post. You need to update manual.

[DCSBL]

5.0006 is indeed not pushed yet, but if this beta runs smoothly it will be rolled out automatically and eventually to everyone.

[Mausy5043]

@Devke1972 I wasn't talking about the beta. I was talking about the public release. Thanks @DCSBL for your answer. I'll wait for the push since I will have more certainty about the stability at that point and as my kWh-meters have become more operation critical.

[DCSBL]

We have enabled automatic installation for 5.0006. This version will now install automatically when your kWh Meter has been added to the beta channel.

[DennisSteenvoorden]

This bèta is now running for more than 1 month fine. No issues.
When will this software pushed to production.
Is there a new beta in the pipeline? With the new cloud servers?

[DCSBL]

Hi all, sorry for the delay.

Version 5.0008 is now available, which fixes some small issues related to stability. This version also fixes an issue where a fourth battery was not able to connect to the kWh meter.

If everything goes smoothly, this version will be released for all users.

[Devke1972]

Ik zie regelmatig de vraag dan voorbij komen wat er nu veranderd is. Idee om het expliciet te benoemen als jullie dit willen delen en een soort tekst op te nemen als het meer een intern dingetje is? Dan ben je de vraag voor denk ik. Suggestie mijner zijde. HW topic tweakers doel ik dan op.

[DCSBL]

We proberen zoveel mogelijk detail te geven zonder verwarring te veroorzaken of onnodige informatie toe te voegen. Veel veranderingen zijn refactors, aanpassingen van flows binnen de code en optimalisaties in het gebruik van CPU en geheugen.

In deze release geven we bijvoorbeeld in een specifieke functie een std::string mee via referentie in plaats van per waarde (std::string&). Dit voegt niks toe voor de meeste gebruikers.

Als er echt iets verandert of belangrijk is, benoemen we dat, zoals tot nu toe altijd is gebeurd.

[Devke1972]

Kan ik helemaal volgen. Mee eens. Op tweakers proberen we vragen te beantwoorden. Soms is dat dus wat lastiger daar het dan dus teveel verwarrende info kan geven. Ik ga dr vanuit als het wel te delen is dat het erbij staat en anders een te ingewikkeld verhaal wordt 👍

[Stef1971]

Staat erop, lijkt goed te werken, geen issues hier.

[DCSBL]

Starting today, the kWh Meter version 5.0008 will be available for all devices in the coming weeks.

[DCSBL]

We have discovered a small issue in 5.0008. The device model was not recognised properly, causing the app to render an invalid image for the product. It also made it impossible to change the display and pulse settings. We have fixed that. 5.0011 is now available as beta. We will make this version available for everyone as soon as possible.

[DCSBL]

5.0011 is now available for everyone.
