Description
Take control of and monitor your world with this ultimate jack-of-all-trades Raspberry Pi HAT!
This home monitoring and automation controller is packed with features to supercharge Raspberry Pi projects. With relays, analog channels, powered outputs, and buffered inputs (all 24 V tolerant), a wide range of devices and sensors can be connected simultaneously.
Each channel includes its own indicator LED for instant status feedback. Even the analog channels feature dimming LEDs that reflect live sensor values—smooth and practical.
Ideal for smart home and automation projects such as greenhouse irrigation, automated fish feeding, or customized scheduling.

Software
As ever, we've made a super-simple to use Python library to take advantage of Automation HAT's multitudinous functions, with examples to get you started.
Our input, output and relay examples show you how to read the analog and digital inputs, switch the outputs on and off, and control the relays.
Notes
- We recommend you use a set of brass M2.5 standoffs with Automation HAT to avoid pins contacting the HDMI port if the HAT is pushed down
- Loads for the buffered outputs should be switched on the ground side, i.e. 12/24 V (from supply) -> load -> output terminal -> ground (from supply)
- The relays can tolerate up to 2 A each and should be switched on the high side
- The sinking outputs can sink a maximum 500 mA total across the 3 outputs, so if you use a single channel you can sink the whole 500 mA across it.
- The accuracy of the ADC is ±2%.
- Do not use to switch mains voltages!
