There are a few docker containers already setup for looking for stock for frequently out-of-stock items like PS5 and newer graphics cards (https://github.com/EricJMarti/inventory-hunter). I’ve tried converting to an add-on with no luck, but perhaps someone with more skill could do so.
Just getting it running would be the first step
Perhaps we can add events or sensors if stock is available (but that would require additional logic)
If they’ve updated the website since I did this, you’ll have to update the parameters of the grep command. It basically just checks for the presence of the queueing page. Here’s the automation:
alias: PS5 Notify
description: ''
trigger:
- platform: state
entity_id: sensor.command_sensor
condition: []
action:
- service: notify.mobile_app_myphone
data:
message: ALERT! PS5 in stock?!
mode: single
