Event triggers - confused

[rbeyers]

Hi guys

I recently discovered this great tool! Many congratulations to all the makers.

I'm confused about making blockly events though. I'm just playing around a little bit and I found that when I create a blockly, for example:

if outsidetemperature > 15
send mail

or

if lightswitch = on
send mail

it will keep sending mails every 30secs or so, as long as the condition is met. Is this normal? I would expect to only send it one time, when the condition was not met before, but is met now.

I know I can bypass this by creating a local variable that will store the previous value, but this is more work.

Is there an easier way?

You can choose to use the NOTIFICATION option on each device to trigger the event (you would need a bash script to do that) instead of use Blocky or LUA

OR.....
you can use a global variable (naming it LightSwitchNotify for example) and evaluate it in the script:

If lightswitch = ON and variable LightSwitchNotify = 0
send mail
LightSwitchNotify = 1
elseIf lightswitch = OFF and variable LightSwitchNotify = 1
set variabe LightSwitchNotify = 0
