Hi all,
First post as I’m just getting started with Home-Assistant.
I’m trying to send some data to a separate system via JSON-RPC.
This is an extract of my config file:
shell_command:
domotiganesthumidity: curl -sS -X POST -H "Content-Type:application/json" -H "Accept:application/json" -d '{"jsonrpc":"2.0", "method":"device.set", "params":{"device_id":122, "valuenum":"2", "value":"{{sensor.hallway_thermostat_humidity}}"}, "id":122}' SERVERIPADDRESS:9090
automation:
alias: Update Nest Temp
trigger:
platform: time
seconds: '/30'
action:
service: shell_command.domotiganesthumidity
And this is what I get when it runs: (preformatted text doesn’t seem to work for this)

if I replace {{sensor.hallway_thermostat_humidity}} with a numeric value (like 45) it all works fine.
Q: How do I parse the humidity value as a parameter to the command?
