I have created a new application which helps you create an audit trail from the actions which occur with in homey.
Tracks
Currently it tracks changes to
- User alarms, (create, delete, update, enable, disable, time)
- Application, (install, uninstall, restart, crash, update available, auto updating, enable, ready)
- Capability (sensors, alarms, doors, lights, everything)
- Device (create, delete, update, name, zone, available, ready)
5.Flows, (create, delete, update, name, broken, enable, move) - Logic (create, delete, update)
- User (create, delete, update, name, enable, present, sleep, verified, favourite devices, favourite flows)
- Weather (update, city, temperature, description, humidity, pressure)
- Zone (create, delete, update, active, child active, moved, number of active devices in it)
- More coming soon.
Output
These changes are tracked both as metadata as well as a human readable string, in can also audit the full current homey object as well as the previous one.

Transport
The audit information is provided back in multiple ways.
- The app creates flows for each of the audits.
- Simple format of data stored and accessible directly from the homey (zipped daily and kept for 14 days)
- Detailed information is stored and accessible directly from home (zipped daily and kept for 3 days)
- BetterStack (https://betterstack.com/) a free (or paid) service.
- SimpleLog app
Flows
This method is only useful as a proof of concept, as many flows will be disabled as they are triggered too often in a decent sized house.
Simple format files
Each file contains a time string the log level and message, each day the log file is zipped up and saved and any log files over 14 days deleted.

Betterstack
By far the best method! Go to betterstack and create a new account, then just add the “id” to the app.
All your audit logs will be available directly with in betterstack,. The free account will keep the data for 3 days.
Betterstack is incredibly powerful, you can choose which fields to show :
You can can also use a query languge to limit what to show.
Each audit can be expanded out to show all the meta data
As well as the full details on the homey object
SimpleLog app
Working with simpleLog app to allow the audit to talk directly to it and have your audit information added directly to the app. This is currently blocked, but hopefully will be available in the near future.
I may add this feature, no promises though
Levels
The app follows the standard simple log levels (to allow easy integration into the simpleLog homey app.
- Emergency (
emerg): indicates that the system is unusable and requires immediate attention. - Alert (
alert): indicates that immediate action is necessary to resolve a critical issue. - Critical (
crit): signifies critical conditions in the program that demand intervention to prevent system failure. - Error (
error): indicates error conditions that impair some operation but are less severe than critical situations. - Warning (
warn): signifies potential issues that may lead to errors or unexpected behavior in the future if not addressed. - Notice (
notice): applies to normal but significant conditions that may require monitoring. - Informational (
info): includes messages that provide a record of the normal operation of the system. - Debug (
debug): intended for logging detailed information about the system for debugging purposes.
Fields
Every audit contains atleast the following information
protected object: {
id: string // The unique identifier of the entity
name: string // The name of the entity, ie. 'My kitchen light', 'Weekend Alarm'
action: string // The action occuring, create, update or delete
entity: string, // The enity which has chnaged, ie. device, alarm, object
fields: string[] // Am array of all fields we have been altered since the last action
reason: string, // An OPINIONATED reason as to why the event is being published, which field changed.
message: string // Human readable message of what has occured
level: string // the level of the audit log (debug, info, notice, warning, error, critical, alert, emergency)
publish: boolean // Whether or not we should ignore the objects alteration
}
Notes
This is all a work in progress about to go to athom for approval, early days.
