I use my Google Home devices to control my smart-home via Home Assistant. This uses the Google Assistant integration in Home Assistant.
For this to work i need to allow the following IP-ranges through my firewall to my Home Assistant instance.
This are the IP-ranges:
- 66.102.0.0/20
- 66.249.80.0/20
- 74.125.0.0/16
- 108.177.0.0/17
- 192.178.0.0/15
I also had to add an IP-address from my ISP (Tmobile/Odido), but this might be from a mobile phone:
- 89.205.130.202
This are some of the IP-adresses i actually saw incomming traffic from:
- 66.102.9.73
- 66.102.9.74
- 66.249.81.133
- 66.249.93.14
- 66.249.93.2
- 74.125.208.72
- 74.125.208.73
- 74.125.208.74
- 74.125.211.7
- 108.177.64.4
- 108.177.64.5
- 108.177.64.6
- 108.177.76.2
- 192.178.13.200
