I want to output the item of a group in the log file that is set to “ON”. To be notified which batteries are empty.

LOG File:

Group-Handling with blockly

Hi, i want to write a rule which sends me a message if batteries of my actors are low. I have a group item which contains all Battery-Low items. With blockly i can write a script like this which logs all item: [grafik] The logging result locks like this: 2021-12-26 18:09:17.088 [WARN ] [org.openhab.rule.c2c315fef0 ] - LivingRoom1_BatteryLow (Type=SwitchItem, State=OFF, Label=Batterie leer, Category=null, Groups=[gBatteryLow, gLivingRoom]) 2021-12-26 18:09:17.101 [WARN ] […

What did I do wrong?

[salexes]

Perfect thank you for posting this, this works great!

Currently it would post the item name into telegram, would it also be possible to post the thing name the item is part of to the telegram chat instead?
