If you like statistics give graphana a look. It’s a very powerful graphing toolkit, given enough time you can create really beautiful views of your data.

If you need aditional data: Many smart plugs can measure power consumption…

Before buying more sensors/actuators: Think about the communication pritocols you want to use:

WiFi

• No additional HW required
• Simple setup
• No battery powered devices or high battery consumption

Bluetooth

• Probably no add. HW req.
• Battery powered devices
• limited range

Zigbee

• good range
• lots of devices
• low power/battery powered
• needs add. HW (usb stick)
• may be a little more complex to set up

(This is just a veeery short summary)

Seems like my scenario is less challanging…

Have you set the sensibility to high and run the ‘empty room’ calibration in the app? (Don’t know the exact enlish name for the option…).

I started out with docker because it looked like a clean and portable solution.

After adding container after container to get the features/add-ons i wanted, various hassles with USB components and networking troubles I ended up with a solution that was a PITA to keep updated.

Then I switched to a RPi and it was smooth sailing (especially integrated updates and backup).

Next step is to move it to proymox running on an Odroid H3…
