Off limit display rules and time counter

[fee_connect]

Hi there,

I have an air quality sensor giving me temperature, humidity and CO2 concentration. limits have been set for good air quality,
I need to realise 2 functions:
- when the variable goes off limit, the font colour needs to change to red
- I need to display for each the number of hour each year the variable was off limits, and reset it on Jan 1st.

Have you done something similar?

Thanks!

Hello, fee_connect

Here is a script for hour counter.

Code:

value = grp.getvalue('38/1/4')
limit = 50

year = os.date('%Y')
key = 'counter_' .. year

if value > limit then
  minutes = storage.exec('incr', key)
  hours = math.round(minutes / 60)
  grp.checkupdate('38/1/6', hours)
end
