Cool Mist ATX

Control your outdoor misting pump from anywhere. Now with sub-second remote connect on cellular and smart messaging when a pump needs setup.

Cool Mist ATX is the companion app for the Cool Mist ATX outdoor misting system. Schedule misting cycles, control one or more pumps, and get freeze-warning alerts — at home on WiFi or away with Cloud Control. Falls back to Bluetooth when your gateway can't be reached, so you're never locked out of the controls you need.

KEY FEATURES

Multi-pump support — pair as many Cool Mist ATX pumps as you own, switch between them from any screen, give each a friendly name

Simple Timer — set continuous spray/pause cycles with a friendly wheel-based editor

Advanced Timer — schedule up to 4 daily time windows with custom days and cycle parameters

Freeze Alerts — get a push notification 24-48 hours before a hard freeze so you have time to drain your pump before pipes crack

WiFi or Bluetooth — connect via your Cool Mist ATX gateway over WiFi, or directly to the pump over Bluetooth as a fallback

Cloud Control — control your pump from anywhere, even when you're not on home WiFi, through a secure encrypted connection

Home Assistant — integrated MQTT support for smart-home automation

Over-the-air updates — gateway firmware can be updated from within the app
