Get current value

Chris Cragg

Seems like a basic question, but how do I retrieve the current reading (temperature in my case)? I know the device is setup to post its value to your webservers (webservices). Is there a simple URL to retrieve that value? Is the twine running a webserver itself?

Twine doesn't run a web server - drains too much power! You can use the HTTP output to send the current temperature. It will call the URL you provide, so you'll need a web service to receive the value.

I tried that. I set it up to call a URL on my server when temp is above -100. It hit the URL once. I expected it to be called at every update. I think we need more rule options.

"When temperature is above X degrees" triggers the rule when the temperature _rises_ above X degrees. Perhaps a language change is in order.

Chris Cragg

So... you are persisting the previous reading, and checking to see if the new reading is greater than the setpoint and the previous is not, then triggering the action? I assume that marks the rule as "applied". How do the Trigger and Reset values play in?

Yes to language change being in order, but I think many of us also want to be able to query CURRENT STATE every minute or 10 minutes or whatever. I would like a log of the temperature of the device over time without having to write 280 rules for rising above or falling below every possible temperature value in its operating range.
