Hello @all,
i am using OH2.5M6 and do some weather stuff with some sensors inside and outside the house. By the way, the problem persisted with M5 and before, but now i have some time to look for the problem.
O.k., what is the problem? Example 1: I measure the windspeed, and i so i have a rule to look what is the maximum speed since last hour and last 365 days. But the value i see at max some hours ago (65km/h) is not the value in the item. And i can see the value in Grafana (65km/h) as same as in the cli. So i am sure that the value is in the database but the rule did not display the right value.
Second Example. I measure the particular matter and with every update of sensor, i store the data in influxdb. That is every 10 minutes. Works. I have a rule which looks for the averageSince…365 days, and get some values. But when i do the same rule for maximumSince, i get an error:
[ERROR] [ntime.internal.engine.ExecuteRuleJob] - Error during the execution of rule 'Feinstaub Maxwerte': An error occurred during the script execution: Could not invoke method: org.eclipse.smarthome.model.script.actions.BusEvent.postUpdate(org.eclipse.smarthome.core.items.Item,org.eclipse.smarthome.core.types.State) on instance: null
That are the Items:
Number TF_FS_10_average "Feinstaub Ø 1,0µm"
Number TF_FS_25_average "Feinstaub Ø 2,5µm"
Number TF_FS_100_average "Feinstaub Ø 10,0µm"
Number Feinstaub_10 "Feinstaub 10µm"
Number Feinstaub_25 "Feinstaub 25µm"
Number Feinstaub_100 "Feinstaub 100µm"
Number TF_FS_10_max "Feinstaub 10µm max."
Number TF_FS_25_max "Feinstaub 25µm max."
Number TF_FS_100_max "Feinstaub 100µm max."
And that is the rule:
rule "Feinstaub Werte"
when
Time cron "1 0 * * * ?"
then
TF_FS_10_max.postUpdate(Feinstaub_10.maximumSince(now.minusDays(365), "influxdb"))
TF_FS_25_max.postUpdate(Feinstaub_10.maximumSince(now.minusDays(365), "influxdb"))
TF_FS_100_max.postUpdate(Feinstaub_10.maximumSince(now.minusDays(365), "influxdb"))
end
And the third thing is, i also looking for min and max temperatures in the last 365 Days. And in Grafana the minium is -1.12°C, but the rules displays -0.,28°C, and when i change the last days to 25, tada, finds the right value.
Is that a problem with the user between keyboard and seat, a problem with influxdb (the i might be in the wrong forum) or a problem with openHAB ?
Whish you all a happy sunday!
