Status error from device

[Nazarbayevv]

Hello,

How can I receive status error from my devices? For example, when device is not connected. I can see this info near dconz input node, but I want to send me notification via messenger

Did you try with a catch node ?

[Nazarbayevv]

Do you mean event node?
This one:

[Zehir]

No the node red one
See : https://nodered.org/docs/user-guide/handling-errors

[Nazarbayevv]

Oh, this one. Thanks. I will try.

You can also check for the state.reachable boolean.
Note that in both case, it's take time for a device to be marked as unreachable

Hello, I tried to use catch node. It didn’t show connecting error. But I use deconz in node together with Apple Homekit nod and I can see not reachable status:

I can take no_response status this way for every nod. Can I do it from single point(single nod)?
