Physically replace failed device

[rumcustomer (leo)]

Does Home Assisntant support “easy way” to replace failed device?
My Aqara Bulb (lamp) fails (was broken).
This device used in many scripts and scenes.
I bought new bulb.
Now i need to rewrite all the scripts with new device address?

Only if you used device triggers, conditions, or actions.

What happens if I have to replace a device

It’s a big problem that you can avoid by not using device triggers, conditions or actions. There are always other triggers conditions and actions you can use instead. e.g. instead of a device turn on trigger use a state trigger. If you only ever use entity_ids in your triggers, conditions and actions then when you have to replace the device you can change the new entity id to match the old one in one place and all your automations keep working. If you use device ids you have to change all of …

And you don’t have to re-write everything. You just need to change the old device id for the new one. Everywhere you used it.

A text editor with a good “find and replace” action should help with doing this.

In future only use entity_ids, not device ids. You can change the new entity_id to match the old one in one place.

Cool! Yes, i can.
Can my mom or grandma or “an ordinary citizen” do it?
Does HomeAssistans team have any plans to make this function user-friendly?

I posted this 2 years ago:

Add a method of replacing devices

Automations associated with a device are marked as unavailable if you replace that device if it is faulty/stolen etc… For state automations you just name the new entity_id the same as the old and… you’re done. For device automations you have to search out all the occurrences of the old device_id and replace them with the new one. You cant just edit the new device id to be the same as the old one. For people only using the UI this is daunting task and they would probably end up re-writing all …

There is also a related WTF post.

WTH there is no easy and automated way to replace devices

So, let’s imagine you have a zigbee bulb which is linked to some automations, scripts and scenes and also is displayed is several dashboard cards. One day is blown and you have to phisically replace it by a new identical bulb (or even similar). You then have to pair it with the zigbee coordinator and there you have a new entity available in HA. Current situation is you have to remember where the entity is used and go automation by automation, scripts, scenes, dashboards… and manually change th…

Due to the lack of movement on this I suggest your mom or grandma not use device automations as instructed above. Hopefully they should be able to change one entity id.

Where is entity_id ?

[tom_l]

To change it, go to Settings → Devices & Services → Entities Tab.

Click on the entity. You can edit the entity id in the pop-up box.

This will not change other places that you have already used the entity id.

Hence it is only useful for making entity ids more understandable if you have not used them yet (do it soon after adding them), or for changing a new entity to match one that is no longer available.

What’s this?
I gave this name on the low-level (zigbee gateway).
And the gateway translate it to Home Assistant.
Can i use it in my scripts, triggers, … ?

[tom_l]

It is the friendly name.

No you cant use it in your triggers. It has to be the entity_id or device_id.

You can edit this name to be something more meaningful to you in the same place I listed above. It can contain capital letters and spaces (the entity_id can not) to make it look pretty in your dashboard cards.
