The Rachio sprinkler controller integration requires HA to be accessible from the Internet so that the cloud can push updates. Has anyone by chance found the IP’s used by the Rachio webhook endpoints so that one can open access specifically from them?
For now I’m just collecting them by monitoring the incoming IP’s on the router (have only seen one so far: 44.237.130.28). This guy asked the same on the Rachio forums and looks like he ended up whitelisting everything above the 44.23.0.0 range, which is still way too open.
