Hello, figured my pool automation project might be of interest here. It was featured on Hackaday a few weeks back, and can be found here. There are a couple of interesting things to it, notably long-range wireless control/monitoring, and single board design (electronics are entirely custom, no need for third-party modules).
For what it's worth, it's helped keep my water quite clear over the summer
