If you're in the middle of automating your home, you've probably faced the big dilemma: touch or physical button? While glass panels look sci-fi, nothing beats the tactile feedback of a real button when you're half-asleep or have your hands full.

Today we’re dissecting the Sonoff SwitchMan M5 series, arguably the most reliable smart switch lineup on the market. Let's look at the differences between the 80M and 86M formats and how to choose the right one for your infrastructure.

📐 80M vs. 86M: What’s the difference?

🟩 80M Series (Square - EU Standard)

• Target: The standard for most European homes. If you have standard round or square wall boxes, the M5-80M fits perfectly without gaps.

🟦 86M Series (Rectangular - Type 86 Standard)

• Target: Ideal for larger boxes or users wanting a wider pressing surface and a more robust wall presence. ✨

🎛️ Control Options: 1, 2, or 3 Channels?

• M5-1C (1 Gang): King of simplicity. Perfect for bedrooms or pantries. 🎯

• M5-2C (2 Gang): The workhorse. Ideal for bathrooms (Light + Fan) or hallways. 🚿

• M5-3C (3 Gang): The Command Center. Total control over your living room circuits in one module. 🛋️💎

🔧 Tech Specs & Features 🤓

• Connectivity: Wi-Fi 2.4GHz + Bluetooth for easy pairing. 📶
