Multi-Item Rules possible

[norbert_jordan (N. Jordan)]

Hi,
i have a group of battery levels (VCC) for battery-driven ESP8266 modules which put their state in Volt every 10mins. What would be the smartest way to check these incoming states and react e.g. via email if any of them is LOW. (e.g., below 3,5V).

Is there a way to define rules that are on behalf of every item in a group to react per item and also send the email with the “name of the pointed battery”.

Like if BatteryKitchen is below 3,5V a email is sent like “Subject: BatteryKitchen is low”…so the rule kind of inserts the right BatteryName of the problematic item.

Hope its clear what I would like to achieve…my guess, the worst situation is that i have to define rules per BatteryItem…because this would be annoying whenever a new batteryItem comes in,…

Many Thanks
Norbert

There are some options for triggering the rule depending on the version of openHAB that you are using. Take a look at the topic below for an overview.

Features for Rules that work with Groups

Introduction This post provides an overview of two features that have been added to openHAB recently to make it easier to write rules that work with groups of items. These features only apply to rules defined in .rules files (also know as DSL Rules), and not any other types of rules/scripts such as those for the Experimental Rule Engine or JSR223 Scripting. The following sections will provide examples of the usage of each feature. These examples will be based on the items shown here. Group All…
