🏁 Purpose

Show the actual status of a fan (which is a present as a switch in Domoticz) on the AWTRIX3 clock, also showing a stopped fan or a rotating fan as the icon.

🔄 Activation and device selection

This Domoticz dzVents script is marked as active by active = true.

The name of the Domoticz device that should be monitored should be selected in the devices = { 'Bathroom fan' } section.

Also download the icons '7426' and '20121' on your AWTRIX3 clock. Those icons are also attached as asset on this flow.

⚙️ Script Logic

Every time when the status of the selected device changes, the state is determined and the rotating or not rotating icon is selected, which is then directly updated as a custom app (with the name 'Bathroom_fan' on the AWTRIX3 unit).

📝 Logging

Logs are generated with the marker "AWTRIX_Bathroom_Fan" to identify entries related to this script.
The logging level is set to domoticz.LOG_INFO, ensuring that informational messages are captured.

🎚️ Flow adjustment

Any generic switch in Domoticz can be monitored on the same way. Just be sure to:

Include the correct name of the Domoticz device in the devices = { .... } section
Update the name of the logging = { marker = "....." } line
Download a suitable 'on'-icon and 'off'-icon on the AWTRIX3 clock
Use the corresponding icon numbers in the dzVents script
If multiple dzVents scripts for the AWTRIX3 are present, update the appData = { appname = "...." } name, to have an individual app page for every script
