What does this app do?
This app connects your Bestway Lay-Z-Spa and Bestway Pool Filter Pump to Homey. Monitor water temperature, control heating, jets and the filter pump, and automate everything with Homey Flow — including push notifications when the target temperature is reached or an error occurs.
