About
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
Demo Mode — try the full app without hardware (tap "Try Demo" on the welcome screen)
The Cool Mist ATX system is designed for outdoor cooling. Pair with a Cool Mist ATX gateway and FG-series pump for the complete experience. Visit coolmistatx.com to learn more.

Change takes effect immediately, persists across reboots, syncs live with the Android app on the same WiFi. Requires gateway firmware 1.4.0 or later (rolls out with your next automatic update). Also includes stability improvements.
