24h Temperature average

Another option is to use storage.

1. Event script to accumulate the values:

Code:

value = event.getvalue()
key = 'average'

storage.exec('incrbyfloat', key .. ':acc', value)
storage.exec('incr', key .. ':cnt')

2. Scheduled script to calculate the average and reset the accumulated values:

Code:

key = 'average'
acc = storage.get(key .. ':acc', 0)
cnt = storage.get(key .. ':cnt', 0)

avg = 0
if cnt > 0 then
  avg = acc / cnt
end

grp.update('1/1/1', avg)

storage.delete(key .. ':acc')
storage.delete(key .. ':cnt')
