Key Takeaway: The matter 1.4 smart home standard is the most significant protocol update yet — adding solar panels, battery storage, heat pumps, certified home routers, and seamless multi-ecosystem device sharing.

1. What Is Matter and Why Does 1.4 Matter?
The matter 1.4 smart home standard is the single biggest shift in home automation since Wi-Fi. Backed by Apple, Google, Amazon and Samsung through the Connectivity Standards Alliance, Matter eliminates devices that only work with one ecosystem.
Version 1.4 turns Matter from promising-but-incomplete into a genuinely useful foundation. It addresses missing energy device categories, unreliable interoperability, and poor Thread network management.
2. New Energy Device Types
Solar Panels and Inverters
Matter 1.4 supports solar power devices including inverters, panel arrays, and hybrid solar/battery systems. Your solar setup can communicate with your smart thermostat to pre-heat or pre-cool when panels generate excess power.
Home Battery Storage (BESS)
Battery Energy Storage Systems like Tesla Powerwall, Enphase IQ or Sonnen can participate in Matter energy management, discharging on schedule for virtual power plant concepts.
Heat Pumps
Matter 1.4 lets heat pumps forecast consumption and shift to off-peak periods, using buffer tanks as thermal batteries — automated without a separate manufacturer app.
Electric Water Heaters
Matter-certified water heaters accept temperature settings and boost commands for rapid heating when demand spikes.
Enhanced EV Charging
EVSE support now includes user-defined charging preferences for cost-optimised overnight or solar-aligned charging.
Thermostat Scheduling
Thermostats gain vacation, home/away and custom modes triggered by motion detection, devices or calendar events.
3. Enhanced Multi-Admin
Matter 1.4 introduces enhanced multi-admin with simplified commissioning, improved Thread border router interoperability, fabric sync, and local network multicast eliminating cloud routing.
A household with iPhone/Apple Home and Android/Google Home users can share the same devices without compromise.
4. HRAP: Certified Home Routers as Thread Border Routers
HRAP-certified devices combine Wi-Fi access point, Thread Border Router, and secure credential storage. Every new router you buy potentially adds Thread coverage without separate dongles.
5. Thread 1.4 and Battery Life Improvements
- Long Idle Time (LIT) protocol — less frequent check-ins extend battery life
- Check-In Protocol — reliable low-power communication
- Quieter reporting — less network traffic for predictable changes
- Credential sharing — border routers join existing networks instead of creating new ones
6. Platform Support
Home Assistant
All 23 Matter device types supported — the most complete controller available.
Google Home
Approximately 19 of 23 device types, with more rolling out through firmware.
Amazon Alexa
Around 18 device types. Matter 1.4 features coming to Echo and Eero through 2026.
Apple Home
Around 14 device types. Full support expected through future iOS and HomePod updates.
7. How to Upgrade Your Smart Home
Step 1: Update Existing Devices
Many Matter-compatible devices receive 1.4 features through firmware. Check for updates first.
Step 2: Audit Border Routers
Confirm at least one Thread border router. Check for HRAP capability.
Step 3: Prioritise Energy Hardware
Verify Matter 1.4 energy category support for solar, battery, heat pump or EV charger plans.
Step 4: Use Multi-Admin Deliberately
Add shared devices to each household member’s preferred app.
Step 5: Maintain Legacy Devices
Keep working Zigbee/Z-Wave networks. Use bridges from Philips Hue, Aqara or Inovelli.
8. Frequently Asked Questions
Does Matter 1.4 support security cameras?
No. Camera support is planned but has no timeline.
Can I use Matter 1.4 with existing Zigbee and Z-Wave devices?
Yes. Matter works alongside Zigbee and Z-Wave via manufacturer bridges.
Is Matter 1.4 backwards compatible?
Yes. Works with 1.2 and 1.3 controllers, though full features need both sides updated.
Which platforms support Matter 1.4 now?
Home Assistant leads with all 23 device types. Others are implementing gradually.
Do I need new hardware?
Many devices get 1.4 via firmware. HRAP routers and Thread 1.4 sensors may need new purchases.
