Red Device Banner only appears after refresh for offline Tasmota (Sonoff S31 Plug)

[lengross]

Using WebUI on Windows 11 (Chrome or Edge) Normal operation seems to work fine: Devices were discovered and the virtual switches react nearly immediately when toggled (ie the “bulb” icon changes color appropriately), Switches are on local area WIFI.

Problem Sequence

• Sonoff is plugged in the wall socket and in the off state
• Switch the Sonoff to “off” using Web UI
• Remove the Sonoff from the wall socket
• Virtual Device icon remains unlit (as “off” – this is fine) Now click on the device Icon to attempt to turn the Sonoff on – (which it can’t because it is not plugged in)
• Wait 5 or more minutes
• No change in device icon or “banner” (e.g. “office”) ever occurs
  • On the browser, hit “refresh”, and the red banner (“office”) immediately appears on the virtual switch

My Configuration:

• Dmomoticz on RPI4 Version: 2023.1 Build Hash: f9b9ac774 Compile Date: 2023-02-14 06:06:40 dzVents Version: 3.1.8 Python Version: 3.7.3 (default, Oct 31 2022, 14:04:00) [GCC 8.3.0] Active User: admin Except for the discovery plugin, the Domoticz has no customizations
• Discovery Plugin Python Source: downloaded development branch on: 06/11/2023 13:42
• Tasmotta binary version11.1.0 (tasmota) 2022-04-13T06:40:42
• Browser Used on Windows:
  Chrome and Edge

Now this could be a problem in Domoticz, or my setup, but seemed like the plugin was the first place to look.
