Edge app for sending notifications when temperatures are under or over a set value with an optional delay.
Input parameters are:
{
"functions": [1,2,3,4]
"overOrUnder: "under",
"threshold": 10,
"delay": 5,
"notificationOutput": 19
}
Notifications are sent with the payload:
{
"function": <function that triggered the notification>
"msg": <mqtt message that triggered the notification>
"last_msg": <last mqtt message of the function that triggered the notification>
"threshold": <configured threshold for reference>
}
If delay is configured to be 0, a notification is instantly sent when a temperature is outside the configured parameters.
In this case the last_msg field is the same as msg field.
If delay is non-zero, the temperature has to be outside the configured parameters for delay minutes before a notification is sent.
Any value reported within the configured parameters will reset the timer, and no notification will be sent.
In this case msg will be the first message that were outside configured parameters and last_msg will be the last message sent before notification.
