I took a different approach in the end. I created a custom Alexa skill and now I am saying things like:
Alexa, ask Homey (my skill name) to wake me up at 6:30
This triggers an AWS lambda that getâs the time from that, and sends it to the endpoint of my home-assistantâs api. Then, my home-assistant automations are taking over from there.
This is the interface I created in my dashboard. Itâs not all functional yet, and the code is a bit too messy to share for now
Maybe the screenshot below can serve as inspiration.
I donât really recall all the steps I took, but Iâll add my lambda code below, and together with an Alexa Skill tutorial somewhere on the net, I think you can manage to achieve the same ![:slight_smile: :slight_smile:](https://community.home-assistant.io/images/emoji/twitter/slight_smile.png?v=12)

Update:
Reading the code above again, I realise itâs importing the requests
module. The downside of importing third-party modules like this one, is that you cannot do this when editing the lambda in the online editor - you have to deploy it instead. This complicates things a bit, especially if youâre not familiair with AWS yet. Alternatively, you can send the requests with the good old urllib
module from python. The syntax isnât super straightforward, so I have put an example call below:
req = urllib.request.Request(your_api_endpoint, data=bytes(json.dumps(data), encoding='utf-8'))
req.add_header('Content-Type', 'application/json')
response = urllib.request.urlopen(req)
