Best procedure to replace a failed device

[drahdiwaberl]

so, i replaced an esp by

• deleting in HA
• downloading firmware
• flashing new hardware
• readding to HA

which replaced everything as expected on the dashboards - but oddly not in the automations which use entities of this device giving the

but since this kind of hash is nowhere to be found hence not easily replaced - how can i get the new device to use this (or change to the new one in the automations)?

Why and how to avoid device_ids in automations and scripts

Background When you start writing automations, a device trigger seems the obvious choice. Everybody knows what a device is and it comes at the top of the UI dropdown list.

this made me think - as i actually never ever am using device_ids in automations, why i even don’t know what they look like.

but surprisingly i found that there was one ‘Device action’ in each of these (rather complex) automations which were shown ‘empty’ in the UI editor - and checking the automations.yaml there indeed were these kind of device_id/entity_ids.

no idea where they came from.

thanks.
