how i can setup a rule with multiple device attribute?
The following should work. Note, however, the rule fires only if one of the temperature values change. In the Rule Editor it is the “Variable Comparison” item. The editing is a bit akward: Remove the suggested quotes
when $sensor-1.temperature >= $sensor-2.temperature then send to: email@example.com subject: you can open your windows
