Nestalarm

Monitor an EnvisaLink alarm module running Honeywell firmware, and set a Nest device to Home/Away depending on whether the alarm is Disarmed/Away.

Setup

• Install the requests library according to requirements.txt
• Setup a config.py file
• Generate the Nest API protobuf python bindings

Example Config

ALARM_IP = "168.178.46.43"
ALARM_PORT = 4025
ALARM_PASSWORD = "user"

NEST_ENDPOINT = "https://grpc-web.production.nest.com/nestlabs.gateway.v1.ResourceApi/SendCommand"
NEST_USER_ID = "2760334"
NEST_STRUCTURE_ID = "015FB2C46740F660"
NEST_ACCESS_TOKEN = "g.0.eyJraWQiOiIyMzhiNTU..."
NEST_USER_AGENT = "Mozilla/5.0..."

Your Nest userid and access_token can be obtained by logging into the Nest webapp and then visting https://home.nest.com/session. You will have to manually change the config when the token becomes invalidated.

Your Nest structure id can be obtained by running the program with an invalid structure id.
