Run one Indigo trigger when any device in a group changes, and keep a readable log of your sensors.

This plugin lets Indigo watch a group of devices as one. It works with any device Indigo knows about, because it watches Indigo itself rather than the devices, so it adds no traffic to your network and needs no account or password.
- Runs one trigger for a whole group, so three motion sensors in a room need one trigger rather than three.
- Lets you choose which change counts — any change, a device turning on, opening or detecting something, or a device turning off, closing or going clear.
- Notes which device set it off in an Indigo variable, so your actions can say which door opened.
- Ignores the housekeeping updates wireless sensors send all the time, such as signal strength and battery level, so a trigger runs when something happens and not when a sensor checks in.
- Keeps an activity log of the devices and variables you pick, such as
Front Door OPEN, in the plugin's own log file, and in the Indigo Event Log as well if you want it there. - Finds your door, window and motion sensors for you, including Zigbee sensors from my Zigbee2MQTT Bridge plugin and sensors from the Matter plugin, and writes the list of what to log.
- Tells you when something it watches is deleted, so a group or the log is never left pointing at a device that has gone.
The group trigger is based on Morris's Group Change Listener plugin, with thanks to him for the idea. The plugin was called Sensor Monitor until version 1.9.
| Part of the plugin | Works with |
|---|---|
| Groups and the Group Changed trigger | Any Indigo device. The ON and OFF choices need a device with an on and off state, such as a motion sensor, door sensor, switch or light. |
| The activity log | Any Indigo device or variable. |
| Finding sensors for you | Door, window and motion sensors, including Zigbee sensors from my Zigbee2MQTT Bridge plugin, Aqara presence sensors and motion and door sensors from the Matter plugin. It leaves out Indigo's virtual devices and the copies the Alexa plugin makes. |

Device_Activity_Monitor.indigoPlugin.zip - Unzip the downloaded file — you will get
Device_Activity_Monitor.indigoPlugin - Double-click
Device_Activity_Monitor.indigoPlugin— Indigo will install it automatically
- Create a New Device, choose Device Activity Monitor and the model Device Activity Monitor Group, select the devices you want in Available devices, click Add to Group ↓, and click Save.
- Create a new trigger of type Device Activity Monitor: Group Changed, pick the group, choose what to Fire on, and add your actions.
- Choose Plugins → Device Activity Monitor → Test Fire All Group Triggers to check the actions work.
- If you want the activity log, choose Plugins → Device Activity Monitor → Discover All Devices (generate config file), and the plugin finds your sensors and starts logging them.
The full guide goes through each step, explains every setting, and covers what to do if something does not work.
v1.11.1 — The Configure window no longer cuts off the help text beside some settings. No setting or behaviour changed.
v1.11.0 — The activity log goes to the plugin's own log file rather than the Indigo Event Log, which it had been filling with hundreds of lines a day. A new setting, Activity in the Indigo event log, with a menu item beside it, puts the lines back there if you want them. Warnings still go to the Event Log.
