Hi,

I am planning to build a diy dosing pum0p setup for a new reef tank. There exist plenty of models already (e.g. https://www.seawatersolutions.de/en/collections/dosierpumpen/products/h2ocean-p4-pro-dosierpumpe-meerwasser-aquarium).

But none of the options I could find can be integrated into home assistant. They all come with proprietary apps or have no smart configuratuion at all. Thus I decided to build my own. This is my first attempt at doing something like this and I need some help vetting my design.

I want to control 4 of these pumps initially: https://www.aliexpress.com/item/32826483616.html

As far as I understand, this should be fairly easy to do by using a smart switch. I'd like to avoid using individual smart switches for each pump, thus I need a multi-channel switch with suitable voltage for the pumps. The switches I could find do not have internal transformers, but finding and adding a matching psu is trivial.

  • 4+ channels
  • 6, 12 or 24 V output
  • preferably wifi

What options do I have when it comes to switches? I have yet to understand what exists on the market and how to find the correct parts.

For something like this I'd recommend looking at esp32 boards with integrated relays. Very simple to set up via esphome and can handle all the communication and integration with home assistant very easily
