This is a very interesting solution to the problem. I started thinking about an automatic fish feeder last year when I realized that summer was coming and vacation trips with it. The aquarium in our house appeared only six months ago, and I used to feed the fish myself. And if a two-day cleanse the fish, I think, would have no problem, then our absence for two or three weeks could be fatal for them. In fact, there were two problems: in addition to feeding, we had to solve the problem by turning on and off the light. It turned out that the problem of lighting can be solved easily with a timer. It is inexpensive and easy to use.
I totally agree. Basically, we are feeding them from Monday to Friday. No food during weekends. We practice this for 2 years and that's fine. But yes, 2 weeks might be fatal.
And for light, we use also timer. Something like this https://cdn.alza.cz/ImgW.ashx?fd=f4&cd=SD030c&i=1.jpg
But if there is a power strike, timer is not synchronised then. So it happen to us, that there was a light during night and no light during the day. So maybe we will change it to Raspberry too. Because it has always correct time after internet connection is back.
