Problem with email/alarm...sending a false alarm

[nightOwl]

I am having an issue that is starting to become annoying with my email/text alarm. I recently had some temperature issues due to a heater failing and so whenever I see the text I think something is wrong. Today I was looking at my status and I received the text. I could see the temp was 78.4. I have received the text/email twice today so far.

I have looked through the datalogs and the graphs and I can not find the temp being over 79.0 today. The datalog is pulling information every 10 minutes. SndAlm_I6 - (base Alarm) and SndWrn_I7 - (base Warn) are both set to Set OFF with no other lines in the programming.

I see where some people suggest creating a virtual outlet to check temperature and things like when the power is off. Is this something that I should use instead? Will adding the defer statement help? Would I need to create two virtual outlets and then have a defer statement for each?

EmailAlm_I5 - (base email)
Set OFF
If Temp > 82.0 Then ON
If Temp < 75.0 Then ON


Email looks like this...
Alarm Statement: If Temp > 82.0 Then ON

Thanks in advance for the help

Since the code executes much faster than the polling interval, it is common to have a discrepancy between the email and datalog. The usual approach is to add a short Defer duration within the email code to buffer out minor fluctuations. Try adding 'Defer 01:00 Then ON' to the end of your email code. This will require that the temp be out of range for at least a minute before the outlet can change to ON.

Todd,
Thanks for the fast reply. Will adding the defer statement handle both of ranges before changing to ON?

If Temp > 82.0 Then ON
If Temp < 75.0 Then ON

Yes; a defer statement will apply to both.

Thanks again To both of you!
