description Raspberry Pi 5 (with HATs) Overview
The Raspberry Pi 5 is not a hub by itself, but when paired with specialized HATs (Hardware Attached on Top) for Zigbee and Z-Wave, it becomes one of the most customizable and powerful DIY hubs available. Its general-purpose computing power allows it to run any smart home software (like Home Assistant) while the HATs provide the necessary radio protocols. This combination offers unparalleled flexibility for those willing to tackle the hardware and software setup.
help Raspberry Pi 5 (with HATs) FAQ
Can a Raspberry Pi 5 replace a Home Assistant Yellow?
A Raspberry Pi 5 can run Home Assistant OS, but it is not the same integrated package as Home Assistant Yellow. Yellow has built-in smart home hardware options, while a Pi 5 setup usually needs separate Zigbee or Z-Wave adapters or HATs.
Which Raspberry Pi 5 feature matters most for Home Assistant?
The Raspberry Pi 5 uses a faster 2.4 GHz quad-core Arm Cortex-A76 processor than older Pi boards, which helps with dashboards, add-ons, and automations. Its PCIe interface also makes NVMe storage possible with the right HAT, which is more durable than relying on microSD.
Can you add Zigbee and Z-Wave directly to a Raspberry Pi 5?
Yes, but the Pi 5 needs extra hardware such as a Zigbee coordinator, a Z-Wave USB stick, or compatible HATs. Many Home Assistant users choose radios based on ecosystems like Zigbee2MQTT, ZHA, or Z-Wave JS.
Is Raspberry Pi 5 overkill for a small smart home?
For a few lights and sensors, a Pi 4 or a small mini PC can also work well. The Pi 5 makes more sense when you want local add-ons, databases, dashboards, and future expansion in one low-power box.
