Variables and WebCoRE

[josh]

@Bry

Create a virtual switch and tile in ST. In webCore, code the switch to be momentary (when it goes on, WAIT then OFF). Also code your variable to increment by some value each time the switch turns on. You’ll probably have to do something to have the heater turn on if the variable increments as well.

You’ll need two switches/tiles. One for up and the other for down.

I haven’t ever used a momentary switch, but theoretically this should work.

We also added some HTTP Request features for power users to the latest beta. We haven’t announced / documented these features yet, but they’d allow you to bypass the need for a Momentary Switch since WebCoRE has the option to trigger a Piston via HTTP.

In your WebCoRE piston, you’d copy the “External URL” (Right Click → Copy Link Address):

Then anywhere that you can use a Hyperlink in SharpTools (eg. a Hyperlink Tile or in the action for a Media Tile), you can use a special syntax for the URL which tells the system to make the request without actually opening the page in a new window:

$.get("https://graph.api.smartthings.com/api/token/XXXX/smartapps/installations/XXXX/execute/:XXXX:", {"proxy": true})

For example, here’s a dashboard with:

1. Hyperlink Tile (Decrease)
2. Media Tile (Current Value, Tap to Reset)
3. Hyperlink Tile (Increase)

Edit: The REST API Hyperlink Syntax feature is now released and you can find documentation on it here:

Edit: And here’s the topic showing how you can display WebCoRE variables in SharpTools (what the media tile is doing in the screenshot above):
