[APP][Pro] Lay-Z — Control your Bestway Spa & Pool Filter from Homey

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.

What’s the difference from your app and this existing app?

A few examples:


(in fact all Lidl app supported devices are also supported by the Tuya Zigbee app)

The app is not additional - still the same app maintained by @rtorkelsen and my contribution with additional drivers which are currently only available in the TEST version.

Update: The new version is now LIVE
