In 2026, centralized management of IoT devices and home automation control are more important than ever. Home Assistant Yellow and Green stand out in this field by offering a robust platform optimized for smart home systems. Unlike these specialized alternatives, the Raspberry Pi 4 Model B remains popular due to its versatility and low entry cost. But which is the best choice based on your specific needs? We’ll examine the pros and cons of all three options to help you make an informed decision.
Why this choice matters
Home Assistant Yellow and Green systems are designed to simplify IoT device management, but each has its own advantages. Yellow offers a complete platform with a Raspberry Pi Compute Module 4 (to be supplied depending on the version) and a built-in Zigbee/Thread radio module (Silicon Labs MGM210P), ideal for complex systems requiring extensive extensions and services. It also provides an M.2 slot for NVMe SSDs and a Gigabit Ethernet port (PoE+ on the PoE variant). Green, on the other hand, is more economical while retaining sufficient power for medium installations with a simplified system. The Raspberry Pi 4 Model B stands out due to its flexibility and low entry cost, although it is less suitable for intensive workloads or simultaneous management of many IoT devices.
Buying criteria
To evaluate Home Assistant Yellow, Green, and Raspberry Pi 4 Model B options in 2026, we used key criteria such as performance, electricity consumption, and compatibility with IoT peripherals. We did not test these products ourselves: the figures on this page are indicative orders of magnitude that we have not verified; refer to the manufacturers’ spec sheets.
Presentation of the 3 recommended products
1. Home Assistant Yellow
The Home Assistant Yellow is ideal for complex systems requiring high levels of customization and extensions. Its performance depends on the Raspberry Pi Compute Module 4 installed (not included in the Kit versions; up to 8GB RAM depending on the CM4 variant), and it has a built-in Zigbee/Thread radio and an M.2 slot for NVMe SSDs. Note: Nabu Casa ended its production in October 2025, so only remaining stock is available.
2. Home Assistant Green
The Home Assistant Green is an economic compromise between Yellow and more basic alternatives. With sufficient power for medium installations, it efficiently manages a certain number of IoT devices without overloading the system. It has a quad-core Arm Cortex-A55 processor at 1.8 GHz, 4GB of LPDDR4X RAM and 32GB of eMMC storage; it has no built-in Zigbee/Thread radio (a USB dongle is required).
3. Raspberry Pi 4 Model B
The Raspberry Pi 4 Model B remains popular due to its versatility and low entry cost, but it is less suitable for complex smart home systems or resource-intensive workloads. However, it offers good performance for simple uses and allows full system customization.
Comparison table
| Criteria | Yellow | Green | Raspberry Pi |
|---|---|---|---|
| Performance | Depends on installed CM4 | Quad-core Cortex-A55 1.8 GHz | See spec sheet |
| Electricity Consumption | See spec sheet | See spec sheet | See spec sheet |
| IoT Compatibility | Built-in Zigbee/Thread radio | Via USB dongle | Via USB dongle |
| Extension and Customization | Easy | Average | Difficult |
| Entry Price | High | Moderate | Basic |
Note: Scores vary depending on the specific system needs.
Use cases
The best option depends heavily on your specific needs. If you manage a large number of IoT devices with high customization and extension requirements, Yellow is probably your best choice. For smaller installations but still seeking advanced features without overspending, opt for Green. The Raspberry Pi 4 Model B remains a good choice if you are looking for a flexible low-cost entry platform for simple or experimental projects.
Pitfalls to avoid
A common risk is underestimating the system’s performance and compatibility needs. Many users also overlook the necessity of regular backups and update management to maintain system integrity. Additionally, improper configuration can lead to unnecessarily high electricity consumption.
Verdict
In conclusion, the decision largely depends on your specific needs for performance and customization. If you seek the best balance between flexibility and performance for a complex system, Home Assistant Yellow remains your best option. For smaller installations but requiring some scalability and advanced features, Green is recommended. The Raspberry Pi 4 Model B remains useful for simple or experimental projects at low entry cost.
