Hey r/Matter community! 👋

I'm the Product Manager leading the development of a new P1 smart meter reader that we're planning to launch later this year. For those who don't know, P1 meters are the standard in the Netherlands, Belgium, Luxembourg, and are rapidly being adopted in Sweden, Denmark, Finland, and parts of Germany . They plug directly into the P1 port on your utility meter and give you real-time access to your energy consumption, production, and tariff data.

Now, here's the big decision I'm wrestling with: should we prioritize native Matter 1.5 integration for this product?

As you all know, Matter 1.5 (released November 2025) finally added proper support for electricity meter attributes, including:

• Real-time power consumption/production
• Cumulative energy usage (import/export)
• Voltage, current, and power factor readings
• Crucially for us: dynamic electricity tariff rates

This is a game-changer because it would allow our meter to expose all this data natively to any Matter-compatible platform, without needing custom integrations or cloud bridges.

But before I push my company to invest the engineering resources into this, I need to get a better sense of the actual demand and ecosystem readiness. I'd love to hear your thoughts on these questions:

My main concerns and questions

1. Ecosystem support status:
   • Home Assistant is obviously all-in on Matter 1.5 and energy management
   • SmartThings was the first to support Matter 1.5 and has been pushing energy features hard
   • But what about Homey? I've seen mixed reports about their energy meter support over Matter
   • Apple Home: They support basic energy monitoring now, but do you think they'll add proper tariff support and energy automation anytime soon?
   • Google Home is still stuck on Matter 1.2 - any rumors on when they'll catch up?
2. User demand:
   • How many of you would actually choose a P1 meter specifically because it has Matter support?
   • Would you pay a premium (say €10-15 more) for native Matter vs. a cheaper model that only works with its own app + Home Assistant via custom integration?
   • Is multi-admin support (being able to add the meter to multiple ecosystems at once) a big selling point for you?
3. Technical considerations:
   • Have you had good experiences with Matter energy devices so far? Any major bugs or interoperability issues?
   • For those who use both Apple Home and another platform, does the energy data sync properly across ecosystems?
   • Is there anything specific you'd want from a Matter-enabled P1 meter that we might be missing?
4. The alternative:
   • If we don't do Matter initially, we'd still support Home Assistant via MQTT and our own API, which is what most P1 meters do today
   • We could potentially add Matter later via a firmware update, but that's always more complicated and risky than building it in from the start

Why this matters (pun intended)

Right now, the P1 meter market is pretty fragmented. Every brand has its own app, and while most work with Home Assistant, it's usually through community-developed integrations that can break when manufacturers change their APIs.

Matter could change all that by creating a truly universal standard for energy data. Imagine buying any P1 meter, scanning the QR code, and having it work instantly with your smart home platform of choice - no custom setup, no cloud accounts required.

But I need to make sure there's actually enough demand to justify the investment. If most people are still happy with Home Assistant custom integrations, or if the major platforms are still too slow to support the full Matter 1.5 energy spec, then maybe we should wait a bit.

What I'm promising you

I'll be reading every single comment here, and I'll take your feedback directly to our engineering and executive teams. If we do decide to go ahead with Matter, I'll make sure to come back and update this community on our progress, and maybe even run a beta program for you guys.

So please - be honest! Tell me what you really think. Would you buy a Matter-enabled P1 meter? What features are most important to you? And what concerns do you have about Matter energy devices in general?

Thanks in advance for your help! 🙏
