Same issue this end, I've emailed support also. Makes this device useless without this integration.
I have followed the instructions on the user guide, and tried both with and without the IFTTT Indicator app, but I cannot get IFTTT to trigger anything on my LaMetric Time device.
I have successfully activated the LaMetric service in IFTTT, and also can see the Indicator app if and when I have it installed on my LaMetric Time, but I cannot get it to show anything. I have the latest available software update on the LaMetric (2.0.18).
