Mine seems to work,
I got a trigger on level 3 and the sms had a level 3 alert,
When it cleared it showed .Level:

So maybe you should redo the firmware. i am using sms firmware 3.03.

Matthias,

The SMS shows what level is alarmed which is great, so when will a sms update be available so that it will also show when sensor is alarmed, as all it says for other sensors is Alarm?, as it can do it for level sensors then it should be able to do it for others.
