How to detect if a device is online

[Wolly76]

Hi all,

I would like to test if a device is online. More specifically a WiFi light bulb. I could retrieve the last-updated-time as well as the state, but both parameter give normal values when the device is on or offline (power is off).
A method might be to ping on the IP address but I couldn't find a way to retrieve the IP address of a certain device as it is handled using MQTT.

Domoticz itself adds a red bar on the device when it is offline, but how to get this information in dzVentz?

Does anybody know how to achieve this?

Thanks in advance.
Regards, Wolly

It should be the .timedOut device attribute that indicates that.
