Plug-In Battery firmware 1.0702 has been released as beta

[DCSBL]

New in Plug-In Battery version 1.0702

• This release has no functional changes.

We have discovered some issues related to the installation of the new inverter firmware, which was installed via firmware version 1.0503, and therefore stopped the rollout of 1.0503. These issues have been resolved in this version. Because we had already started to work on firmware version 1.06xx, we had to skip this version; therefore, we jump directly to 1.0702.

How to install

The update will be installed automatically. To check if your device has the latest version and to install this 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.

First battery which was on 1.0503 refused to update twice due to timeout. And while I am typing this it did so on its own, go figure.
Second battery is still on 1.0406 and simply does not detect any upgrade version.

But everything (seemingly) works as I intent via HA automations so no big issue, I suppose ?

Both batteries updated, but the Software and Wi-Fi percentage values are blank in the HW app.

Version 1.0702 installed, currently sync net frequency. No sun at this moment so will monitor.

[DuncanTheFox]

Three batteries updated without a hitch. No spread, no sun so no real testing. I changed the modes to;

Manual charge, check, charging works.
Zero mode change works, check. No Watts.
Zero mode (charge only) change works, check. No Watts, no sun.
Zero mode (discharge only) change works, check. No Watts, PiBs empty.
Standby works.

Seeing an improvement, after manual charge for a moment, no 6-7 Watts of usage for half an hour. Mere seconds.

Als je SoC 0% is dan was dit altijf al zo. Bij meer dan 1% zou het nieuw zijn.

Here exactly the same. The batteries one and two on 1.0503 are successfully updated to 1.0702 The battery three on 1.0406 does not detect an update. It didn’t see the 1.0503 update earlier as well. What can I do get this battery updated as well?

3 batterries updated to this version without a problem.

[PSMGoossens]

On one battery I got a 203 error once again. After rebinding to P1 meter it is solved, but last firmware updates it was the same behavior

Was er al bang voor. Zou wel mooi zijn... Op wo 11 feb 2026 om 17:53 schreef Devke1972 ***@***.***>:

Biede pibs geupdate, geen centje pijn

[mgdijkerman]

Beide pib's geupdate, helaas blijft er 1 op error E203 hangen. Herstarten, spanningsloos maken, wifi opnieuw verbinden hebben geen herstel gegeven. Ik heb reeds Wizzi gecontact, hoop nu op antwoord van support.

Kun je een e-mail sturen naar beta@homewizard.com met je HomeWizard-account (een e-mailadres) en het serienummer of de serienummers van je apparaat of apparaten? Een serienummer begint met 5c2faf of 3c39e7. Dan ga ik even kijken of we iets kunnen ontdekken.

[DCSBL]

Starting today, Plug-In Battery version 1.0702 will be made available for all devices in the coming weeks.

[RowanUtrecht]

@DCSBL Hoe lang kan zoiets duren als niet Beta tester? Kan ik iets doen om hem sneller te krijgen. Ik heb al op updates zoeken gedrukt

[JanSmart93]

Helaas al twee weken na update werkt de batterij niet meer. Zelfs als je batterij spanningsloos maakt blijven de ledjes wit branden. Onder spanning wel wifi verbinding. Onder spanning wel wifi en verbinding met de P1.
