I would like to see a Wyze aquarium controller system. It seems like a lot of the functionality for this already exists in the Wyze app with the rules engine. Most controllers come with a power bar with maybe 8 plugs. Then, you have sensors for pH, Salinity, temperature, and ORP.
What I think would be a lot of extra work would be integrations of controlling other flow pumps.
I feel some type of controller that could control power bars, and monitor pH, temp and salinity for $200 or less would be a big seller. There are likely options to have subscription options for maybe an Aquarium Plus subscription service as well. Add on like Wyze dosing pumps to go along with the controller. I see a lot of possibilities.
