I have already started the process of a side project by desiging the software, the architecture, the 3d model, ordered all the electronics of a pet 'smart' stable for my guinea pigs.

Which would automatically feed them and refill their water tanks silently but for me the point on playing around with dozens of sensors for like different water levels, water quality, hay, temperature, water quality (you get the point) ... Building a nice looking web interface or an App to control everything and get a live feed from different angles ( sounds a bit crazy altogether but it looked like a cool project )

I even started a instructable and had a github repo for sharing the source of the app/web interface and the whole micro service based server

I'm still at it and hopefully will start to build the ***ing wood and acrylic parts in the next month's but currently and for the last month's free time ist my archenemy

Keep you posted if you are interested 😀
