Homey Pro 2023 Hardware Upgrade (Windows 10 and 11)

Introduction

Let’s face it: I’m a massive gadget geek. I’ve previously wrestled with the eternal question of Home Assistant versus Homey Pro on this blog, but today is about hardware. I decided to write in English, because I suspect I’m not the only one struggling with this.

Just a few weeks ago, the new 2026 Homey Pro hit the shelves. It boasts 4GB of RAM—a solid upgrade from the “old” 2023 model’s 2GB—but it still clings to the same limiting 8GB of storage. Sure, the out-of-the-box specs are an improvement, but for those of us who push our smart homes to the limit, 8GB of storage hits a wall pretty fast.

I went down the rabbit hole and found that swapping the engine in the 2023 unit is entirely possible, effectively letting you build a machine that beats the factory specs. The problem? Most existing guides were outdated and flat-out refused to work on my Windows 11 machine.

So, after hours of tinkering (and more than a little frustration), I’ve cracked the code. Here is my personal, battle-tested recipe on how to do it yourself.

The mission is simple, but the impact is massive. We are going to transform a standard Homey Pro 2023 from a modest 2GB RAM / 8GB Storage unit into a future-proof machine with 8GB RAM and 32GB Storage.

With the 2026 model taking the spotlight, you can often find the “older” 2023 version at a significant discount. By grabbing one of those and performing this upgrade, you aren’t just saving cash; you are building a system that actually outperforms the brand-new flagship. You end up with double the RAM and four times the storage of the 2026 model, all for a total cost that is lower than buying the new unit off the shelf. It is the ultimate smart home hack.

For the 2023 model you really only have about 1.5 GB of usable space to play with. By swapping the Compute Module (CM4), we unlock serious headroom:

• Stock Homey Pro 2023 (before upgrade): ~1.5 GB free RAM | ~1.6 GB free Storage
• Modded Homey Pro  (after upgrading): ~7.7 GB free RAM | ~24 GB free Storage

Is it overkill? Maybe for some. Is it worth it? Absolutely.

Ingredients for your Shopping List

Before we start turning screws in the next chapter, we need to get the parts sorted. Raspberry Pi Compute Modules can be found easily but be aware of the following:

The Critical Component:

• 1x Raspberry Pi CM4 Module (CM4108032) – Danish onlineshop – CM4=Compute Module 4 (wifi)
  This is the heart of the operation. You get 8 GB RAM and 32 GB eMMC storage.
  IMPORTANT: You must buy a module with WiFi. Check the model number carefully: It must start with CM41…. If it starts with CM40 just skip it as it has no WiFi, and it will not work in your Homey.

The Toolkit:

• Windows PC: You need at least 2 GB of free space for backups and flashing (windows 10/11).
• Torx T9 Screwdriver/Bit: For the main case screws.
• M5 Hex Socket/Driver: Or a small wrench if you are careful.
• Plastic Spudger/Opening Tool: To open the case without scarring the plastic.
• Needle-nose pliers and/or a side cutter: Essential for the tiny cooling plate which need to be altered a bit (pictures later).
• I bought af “IFixIT” computer repair set (and had the needle-nose pliers/side cutter.

The Roadmap

We are going to take this step-by-step to ensure you don’t end up with a bricked device. I’ve boiled the process down to 4 manageable parts. I’ll have this paragraph in each post in order to easily go back and forth:

• Part 1: The Strategy & Shopping List (YOU ARE HERE)

• Part 2: Backing up the Homey OS

• Part 3: Swapping the CM4 Module & Restoration from backup

• Part 4: Unlocking Potential – Jailbreak & Storage Expansion

Get your parts ordered, and I’ll see you in Part 2 where we get to the real work. Over the next days I’ll publish the next chapters. Please be patient 🙂
