It absolutely is. I have 4 RPi devices in the house actively doing work and I only touch them when I need to change a feature or something like that.
1. Front end to my 3D printer - RPi 2.
2. Magic Mirror - RPi 4.
3. Front end to my ancient HP LaserJet to make it wireless - RPi Zero W
4. Detector for Dryer finishing and sending me a text message - RPi Zero 2 W
These require no babysitting whatsoever.

- starik36 3y agoMy RPi 2 with the 3D printer has been operating with no problem since 2017 or something like that. The RPi Zero W with the HP LaserJet since around 2019. Fingers crossed, it's been fantastic reliability.
- dgacmu 3y agoHow do you tell when the dryer is finished?
- starik36 3y agoI bought a Kasa Smart Plug (https://www.amazon.com/dp/B08LN3C7WK https://www.amazon.com/dp/B08LN3C7WK). It has an API for reporting energy usage. Luckily there was already a library (https://github.com/python-kasa/python-kasa https://github.com/python-kasa/python-kasa) for calling this API. I wrote a small console app that checks energy usage and when I detect a drop, I know that the dryer is done. Then the app uses Twilio to send me a text message. This is my second attempt at solving this problem. In the first incarnation, I attempted to do audio recognition for the sound that the dryer makes when its done, but I just couldn't get it to work well. The sound was too short to generate a good signature.
