Home Assistant has officially ended support for all 32-bit ARMv7 devices, which includes Raspberry Pi 2/3/4 (32 bit installs), ODROID-XU4, and ASUS Tinker Board. These platforms will no longer receive any updates including security patches or compatibility improvements. Home Assistant will now be focusing on modern 64-bit hardware only.
Our HAS series are all 64-bit, they will be unaffected by HA decisions and will continue to receive support. Also our architecture aligns with what Home Assistant OS, Docker, and modern add-ons are optimised for.
All SmartHomeShopUK Home Assistant Servers come pre-installed with Home Assistant OS, providing reliable, local smart-home control with silent, fanless operation.
The table below outlines the key hardware differences between the three current models — HAS-B1, HAS-B2, and HAS-H3.
| Model | Processor | Memory (RAM) | Storage (SSD) | Ethernet | Wireless | USB Ports | Video Output | Notable Features |
|---|---|---|---|---|---|---|---|---|
| HAS-B2 | Intel® Celeron 2955U (Dual-Core) | 4 GB DDR3 | 64 GB SSD | 2 × Gigabit Ethernet | Wi-Fi + Bluetooth | 8 × (USB 2.0 / 3.0 mix) | HDMI & VGA | Great budget model for starting HA journey |
| HAS-B1 | Intel® Celeron 2955U (Dual-Core) | 8 GB DDR3L | 128 GB SSD | 2 × Gigabit Ethernet | Wi-Fi + Bluetooth | 8 × (4 × USB 3.0 / 4 × USB 2.0) | HDMI & VGA | Higher RAM / SSD — best all-round choice |
| HAS-H3 | Intel® Celeron J4125 (Quad-Core 2.0–2.7 GHz) | 4 GB DDR4 | 128 GB SSD | 2 × Gigabit Ethernet | Dual-band Wi-Fi + Bluetooth 4.0 | 4 × USB (2 × 3.0 / 2 × 2.0) + 2 × RS-232 | HDMI (4K) & VGA | High performance, premium model |
Efficient dual-core system great for budget installations or first-time Home Assistant users.
Offers full connectivity in a compact, fanless form factor.
Upgraded configuration with 8 GB RAM and 128 GB SSD for smoother multitasking and more capacity for add-ons and long-term data storage, the best all-round option.
Even higher performance, made for enthusiasts and larger deployments.
All HAS models use 64-bit x86 processors, ensuring full compatibility with current and future versions of Home Assistant OS. Unlike legacy 32-bit ARMv7 platforms, x86_64 provides a larger address space, improved container stability, and broader support across modern Linux distributions. This allows your Home Assistant instance to run larger add-ons, more integrations, and more advanced automations without system limitations.
Despite using x86 processors, HAS units are designed for 24/7 operation and consume significantly less power than traditional desktop PCs. Typical draw is in the 7–15W range depending on workload, which is comparable to mid-range ARM-based SBCs while providing substantially higher performance and reliability.
We stock a large range of Home Assistant servers that come pre-installed with Home Assistant OS. Each machine is hand-picked to provide reliable, local smart home control with silent, fanless operation. Below, we compare the specifications of each model so you can decide which one is the right choice to run your Home Assistant server on.
You’ve probably heard of Matter — the new smart home standard backed by Apple, Google, Amazon, and others. It promises to fix compatibility headaches by letting all your devices talk to each other, regardless of brand or ecosystem.
Sounds great. But if you’re already deep into smart home setups — especially with Home Assistant and Zigbee — you might be wondering: is Matter even relevant to me?
Winter is when energy bills hit hardest — and it’s also when smart home technology proves its real value. While no single device is a magic fix, the latest research shows that well-designed smart heating systems consistently help households cut waste, improve comfort, and make heating far more efficient during the coldest months.
