Ports required
Port 80 → Used for HTTP requests
Port 123→Used for getting the time (for example, my Pro 2019 uses 0.debian.pool.ntp.org)
Port 443→Used for HTTPS requests
So nothing special here, as far as I can find. If you have a Pro 2023 or a Bridge, and it uses more ports, please let me know.
Note: this is all based on a combination of network request interception, the explanations on status.homey.app, subdomain searches and assumptions. This information might not be accurate, if you see anything incorrect or missing here, please let me know!
