Trends keep 1 hour of object values sampled every minute which you can use. This won't be a true average though because any changes between sampling times are lost.
This example will fetch values from the past 30 minutes and calculate the average value.

require('trends')
date = os.date('*t')
time = os.time(date, true)
daterange = {
['start'] = time - 30 * 60,
['end'] = time,
}
data = trends.fetch('my trend', daterange, 60)
avg = 0
count = 0
for index, value in pairs(data) do
if value and value == value then
avg = avg + value
count = count + 1
end
end
if count > 0 then
avg = avg / count
end
log(avg)
