Thanks for the response - much appreciated.
New to Home Assistant …
Is this yaml? and do I just create an automation, edit in yaml and paste it in there?
Do you have it set to start on boot?
It’s still interesting though since the add-on shouldn’t be affected by a restart of Home Assistant. It would be affected by a reboot of the host though.
it is an automation, so this should work:

yeh
It is a consistent issue, took me while to understand why my graphs on Dashboards were failing, I am using Node Red from my standalone zigbee2MQTT days so the Home Assistant automations, I have very few of them, were not having an impact.
I don’t always remember to restart zigbee2MQTT so a bit of a pain
Is this useful
from the zigbee2MQTT log
[16:39:08] INFO: Preparing to start…
[16:39:09] INFO: Socat not enabled
[16:39:09] INFO: Starting Zigbee2MQTT…
Sorry to be a pain - where do I find the add-on name for my installation?
Could be a misconfiguration
MQTT config :
and Zigbee2MQTT status
So Zigbee2MQTT knows HA has restarted.

Settings → Add-ons → Zigbee2MQTT. Look in the URL
I found it in the url - I use the Mac App - would never in a million years found that! Thanks.
It doesn’t like something - sorry for being a noob.
zigbee2MQTT config looks good without any changes - default install
Where MQTT config options above? I cannot find that config page
You could simple paste it in automations.yaml. Sorry, I don’t use the automation editor.
Ok… that will be a first for me 
Setting → Devices & Services → MQTT → Configure → Reconfigure MQTT , second page.
Thanks you ar taking me to dark corners of config I had not previously seen
Looks Ok
I took everything default install
But it can…
And in case you want to import yanl:
description: “”
mode: single
trigger:
- platform: homeassistant
event: start
condition: []
action:
- service:hassio.addon_restart

You are barking up the wrong tree as z2m does not need to be restarted on HA restart.

Ok
How do you get Home Assistant to not lose all the zigbee2MQTT devices after Home Assistant restarts?
At the moment every time Home Assistant restarts, short of a complete shutdown, restart, Home Assistant loses all zigbee2MQTT devices.
Everything is setup as default, so if any ideas on how to get Home Assistant to behave as you stated I would be greatly appreciated.
Perfect!,
Done and dusted, will keep on trying to work out how get Home Assistant to not lose zigbee2MQTT devices after a restart, but this will keep it going in the meantime.
Many thanks all!

Here you have homeassistant/status, in Zigbee2MQTT you have hass/status. These have to be the same.
If they are the same, Zigbee2MQTT resends the MQTT discovery messages on HA restart, and it does not need to be restarted.

I suspect you have hit the nail on the head.
Although mine has different (same as @Busta999x hass/status in z2m and homeassistant/status in the mqtt config. And yet mine works.
