Indigo Domotics

I've created a day zero forecast device called WeatherToday which appears to be working. I can't get the syntax right to get the max temperature in a script.

I would have thought it would be indigo.devices["WeatherToday"].tempmax but its not.

What is the correct syntax?

Thanks

I've setup two triggers on the Maximum Temperature so set and unset a boolean variable, but they don't appear to be firing even though tempmax is over 20c.

Have I done something wrong?
