## What is Warmup WSM?

Let the weather forecast activate your snow melting system. Warmup’s WSM-252W requires no sensors and automatically manages your snow melting system based on parameters set in the app.
-Pre-heating: only the WSM-252W can activate the system in anticipation of the snowfall. Typical sensor-based controllers are reactive and require too much wattage and amperage
-All in one: no more sensors or j-boxes. The WSM-252W is 12x12x6” with everything built-in

### 1/5 — Very buggy

*2024-02-20*

This app is full of so many bugs. Really disappointing considering how expensive our driveway heater is to run. 

 - Weather tracking almost never seems to be accurate. And just a week or two ago their weather servers were down for almost a week.

 - On IPhone the app always has to be killed to get it to refresh to the most recent data 

- If you turn it on or off manually sometimes the automation takes over and sometimes it doesn’t. Seriously just add a manual and automatic mode toggle

- The notifications for the system turning on/off also have never worked

### 3/5 — Not bad but app needs work

*2021-12-21, version 1.0.12*

Works as expected took a few tries to get it to connect to my system. Notifications not working still on iOS 15.2, no option to toggle from Fahrenheit to Celsius. Schedule feature needs some work, manual on feature should have a timer to set how long it should run when manually triggered. Logs would be nice to see how long it’s been running for when it was triggered etc.

### 5/5 — Simple app. Does what it should.

*2021-06-14, version 1.1*

Works the way I expected to, so far. Good options for override and preheating. Pretty simple app that does what it’s meant to.
