Remote restart over the websocket (from Home Assistant)

[greenbus4]

When my POE (Serial over Internet) controller is power cycled (e.g. switch restart) Z-Wave js doesn't reconnect. To bring back the network I have to restart via the ZUI interface (or restart the ZUI container).

I see the server has driver.soft_reset. Would that accomplish the same thing? And if so, is there any way to send that command via the current HA integration?

Here's my versions and the error. Once that error happens Z-Wave js doesn't attempt to connect again.

zwave-js-ui: 11.17.0
zwave-js: 15.23.5

@AlCalzone could be related to #4451 ?

I missed that issue in my search, but I'm also curious in general about remote restart (from HA). Thanks.

That's a questrion for Home assistant BTW, dunno sincerly

I've started some work on exposing Z-Wave JS UI's websocket API to HA, but it is not done yet. This would allow things like the remote restart, or syncing node information (name, location).
