Too long since last update - chriscroko - 20.10.2018
Hi,
I would like to do the following:
- tag all temperature readings
- search up these temperature readings that are tagged
- get the oldest timestamp
- if timestamp is older than two hours
= write a boolean 1 on a group address
This way I could indicate that there is a sensor on my installation that is not sending the current temperature anymore.
Hope this could be done with a script. In advance thanks.

Hi,
I think you need something like this:
Code:
output = false
max_timestamp = os.time() - 7200 -- 2 hours in seconds
for _, object in ipairs(grp.tag('temperature')) do
if object.updatetime < max_timestamp then
output = true
break
end
end
grp.checkwrite('1/1/1', output)BR,
Erwin
