I want to build a home automation bot but I don't know what kind of features to give it. I have hue lights and I want a smart speaker/google home mini. Do you guys have ideas? I'm open for everything.

Maybe the bot should be able to controll the heating

What would you like it to controll and what do you think would be easy to use with voice control.

Lights, lights out
Music, silence, higher, lower

Try to think of what could be controlled without to complex commands.

There are lost of voice interpreters that can handle simple commands and relays to turn power on and of and stereos that either have some controll interface or a remote that could be fakes with an ir doid.

The important thing is start with some easy thing to get something working and then extend that.

@Tobey I don't have a nest thermostat. I have a pi that I need to hook up but I don't know wat te run on that, probably the bot

@Voxera thanks, this helps!

Maybe you should start with turning on/off some devices?

Setting alarms and timers is a good place to start

Speakers!! Very important 😊😊

Here is a bunch of ideas:
- The raspberrypi can act as a fm transmitter (but may be illegal).
- It can block ads using pihole.
- Can be a simple (not very fast but sufficient) nas storage with a flash or external drive
- Control circuits (e.g. communicate with an Arduino, emulate your pc power button, ...)
- Down or upload large files while you're sleeping and are not using your internet
- There are ways to turn the rpi into a google home speaker
- Use openvpn to access your network from outside (or encrypt your connection in a public/monitored network)
- Use one as a media center (Kodi) or game console (RetroPi)
- Hook it up with a webcam to use as a motion detection system
- Extend your wifi range with a extra wlan stick acting as a hotspot

Getting into microchips also might be worth. You could, for example, program an esp8266 to send sensor data (brightness, temperature, ...) over the integrated wifi to your raspberry pi to manage that.

Also, with a smart speaker like a google home (or the assistant app) you can add your own voice commands using IFTTT and the webhook option which can trigger events on your rpi (need to forward port 80 and 443).
