Big Red Smart Button

Ever wanted to slam your hand down on a big red button and have it trigger your smart home? Now you can!

This case houses a standard 22mm button (I recommend [this one from Amazon]) along with an Aqara smart button to trigger Home Assistant actions. Use the customizer to create a custom label ring for your button.

What You'll Need

• 22mm big button (this one from amazon)
• Aqara smart button
• Soldering equipment
• Spudger (for opening the Aqara button)
• Threaded inserts
• Bolts

Assembly

1. Prepare the Aqara Button

Open the Aqara button using a spudger, then solder leads to the existing switch (or remove the switch and solder directly to the pads).

2. Choose Your Case Variant

• SHORT variant: Use this if you leave the Aqara lid off (recommended—saves space since the original button won't be reused)
• LONG variant: Required only if you reattach the Aqara lid and factory button

3. Final Assembly

Wire the button, insert the threaded inserts, and bolt the case together.
