I am new to Meteobridge and am using the software with a Acurite 5 in 1 sensor and internet bridge. I would like to create an alarm condition that will email me when the bridge does not receive any valid updated sensor data for 15 minutes. COuld someone point me in the right direction of how to approach this? Note that I have am email alarm working now that emails me when rain is sensed each day.
As a bonus, it would also be great to have an alarm that would email me when the sensor batteries are low or the signal is very weak.
Alarm to email me when sensor reports no new data

Re: Alarm to email me when sensor reports no new data
As mostly... it is in the wiki: http://meteobridge.com/wiki/index.php/T ... _Variables
Variable "mbsystem-lastgooddata" returns number of seconds passed since last data reception.

Re: Alarm to email me when sensor reports no new data
OK, I will work with that System variable. Do I have to specify a sensor for the lastgooddata variable to work or does it report for any/all sensors? Could you give me a couple of examples of how I could use lastgooddata to see if my 5 in 1 has reported no useful data in the last 5 minutes?
Re: Alarm to email me when sensor reports no new data
In response to my previous post would the following work for a one-time alarm email?
Raise Condition: [ [mbsystem-lastgooddata] = -1 ] || [ [mbsystem-lastgooddata] > 300 ]
Clear Condition: [ [mbsystem-lastgooddata] != -1 ] && [ [mbsystem-lastgooddata] < 300 ]
Subj # Body: No PWS Data Alarm # No PWS Data received for [mbsystem-lastgooddata] seconds.
I think this would email me when there is no valid data or no new data for 300 seconds (5 mins). If what I read is correct it would send one email when the raise condition is met and not send another unless the clear condition is met and then another raise condition is met. I am choosing one-time instead of periodic because I think I would get many emails in an extended outage situation. I really am just looking for an email to alert me that something is wrong and to investigate. Would this work OK?

Re: Alarm to email me when sensor reports no new data
1) Priority of evaluation is given by rounded brackets (not square ones), as we learned in school 
2) Raise condition will trigger you each time data logging is started. When you don't want this, just put "[mbsystem-lastgooddata] > 300" as raise condition.

Re: Alarm to email me when sensor reports no new data
I thought that the square brackets were required when using system variables. Where are you suggesting that I use () instead of square brackets? Should I not use the -1 check at all for my application? Also, is my clear condition ok?
On a lesser important note, I do not get any emails from this forum when someone replies to my posts, is this normal? I am just checking periodically.

Re: Alarm to email me when sensor reports no new data
variables in square brackets, numeric expressions in round brackets...
raise: [mbsystem-lastgooddata] > 300
clear: ([mbsystem-lastgooddata] >=0) && ([mbsystem-lastgooddata] < 300)
raise: [mbsystem-lastgooddata] > 300
clear: ([mbsystem-lastgooddata] >=0) && ([mbsystem-lastgooddata] < 300)
Re: Alarm to email me when sensor reports no new data
Ok, thanks for the help... I will give this a try.
Re: Alarm to email me when sensor reports no new data
My alarm to notify me when no good data is working however I have outdoor and indoor sensors. Is there a way to specify lastgooddata for only the outdoor rain, wind, etc sensor?
Re: Alarm to email me when sensor reports no new data
No, will check if there is an easy way to add this.
Re: Alarm to email me when sensor reports no new data
Did incorporate this in the update just released.
