Vibration Sensor

https://joshmccarty.com/how-to-increase-sensitivity-on-aqara-vibration-sensor-with-home-assistant-zha/

I recently purchased an Aqara vibration sensor, but the default sensitivity wasn’t working for my application. The sensor was connected to Home Assistant via the Zigbee Home Automation (ZHA) integration using a GoControl HUSBZB-1. I didn’t see an obvious way to change the sensitivity on the sensor, but fortunately I came across a forum post with the instructions.

In Home Assistant, go to Configuration > Integrations and configure the Zigbee Home Automation integration.

• Click/tap on Devices and open the device for the vibration sensor.
• On the device screen, click/tap on Manage Cluster. In the dialog that opens:

How I made my doorbell smart

The Problem

I have a simple door entry phone that buzzes when someone rings the bell and lets me 'buzz' them in. I would like some smarts. Firstly I want to be able to notify and automate when someone rings and secondly I would like to be able to buzz people in.

Entry phone systems vary throught the world and so it is unlikely this write-up will work for you, so I have spelt out the general principles I used and the steps I took.

The ingredients:

• Raspberry Pico W
• ESP home installed on the above

Shortcut and On/Off switches

1. Remove back cover with philips scredriver and instert provided battery
2. In home assistant select a ZHA always-on zigbee device - such as a powered light or signal repeater in the same room the shortcut button will end up in
3. Select "Add device via this device"
4. Press the pair button 4 times on the back of the shortcut button
5. Wait
6. If using an On/Off switch and you want to bind it to a bulb for non-controller dependant control (i.e will work if home assistant is down)

How to wire a 3 position momentary switch to a Tradfri on off switch

The problem

My better half is keen on having Chrome light switches in our house. Unfortunately I am keen to control our smart lighting with Tradfri switches. My original plan was to buy blanking plates and then simply stick the Tradfri On/Off remotes to them. Unfortunately the white plastic on the wife's chrome blanking plates look terrible.

The Idea
