Tellstick.net, remotestick, Viking temp sensor, Tasker

[Beginner]

Hi, I'm a beginner. Installed Remotestick, Telldus live & Tasker apps on my HTC One. Want a temp. alarm in my cottage. Have a Viking temp sensor. Set up a temp. alarm using variable value%"sensor name"<5》Task notify where I just added a sound file. If the temp goes below 5 it works fine. Then I changed mobile to a Samsung Galaxy Note 3. And did the same programming. But it does not work. The alarm now goes off when turning on the Samsung mobile.... But not when the sensor goes below 5 degrees.... Sensor values are visible in both Remotestick and Telldus live apps on the Samsung. Any tips much appreciated!
