Homey Cloud - http requests

Questions & Help
#1

Hi All,
i am implementing my Homey Cloud setup and it goes well, now i want to explore its connectivity possibilities. At home i have the bridge talking to the Homey cloud (hosted on AWS Frankfurt inside a docker container i believe). With a logic card, you see the option ‘HTTP request’. I suspected already that this request is not sent from the bridge using a private ip, but its sending from a public Cloud ip.

So i did a little test, on my FW, i forwarded both http and https to a win10 pc with wireshark (and its win FW opened for 80 & 443). when sending from a test flow the http request to my public ip, then indeed i saw in wireshark the request attempt coming from a public AWS address. Sending https did not work, in the flow i got a exclamation mark, and nothing in wireshark. of course, that could be because of missing certificates and its ssl offloading.

The questions i have:
-is there a standard domain name or fixed ip used by Homey cloud to send the http requests ?
-Despite saying ‘HTTP request’, is HTTPS also working ? (i do not want to send plain http over the internet

This way, using the http request from Homey cloud, i could even send this back to my home network and get it processed there (but only with https, http is not secure enough)

Thanks

I doubt it.

It should work, but only if the HTTPS endpoint provides a properly (CA-)signed certificate.

From what I understood, OP is looking for the other way around: sending HTTP(S) requests from flows.

“At home i have the bridge talking to the Homey cloud”, so I assume there’s no Homey Pro in play.

To really add something I hope:

There are several sites online to return your info, fe http://httpbin.org/anything but maybe only for Advanced Flows as it returns the info in JSON.

But with a Homey (cloud)

Go to https://webhook.site/ and copy the generated URL there and switch to another Tab to create your Flow:

Then Execute the Flow from Cloud and see the result in your original WebHook.site TAB.

Here the links from two Athom Pods:

  • prod-eucentral1-001
  • prod-useast2-001

Ow, and for the ones with a Pro with Advance Flows:

(Latest also works with https :wink: )

BTW: A restart of Homey (cloud) did not direct change my source IP address, not yet… No guaranties for when Athom does maintenance!

thanks, useful info. The only reason for a fixed source ip might be when i route the request back to my home lan for further processing, so i can whitelist the source ip. But whois ip showed it comes from aws ip range. At least i can limit to aws ip.
