REST API Example

[Davide Nastri]

Hi everyone.

I would like to turn on and off switches in Home Assistant with REST API, mainly to let it interact with my Tasker.

I read official documentation but I do not understand how I should structure my call to change a switch status.

I think I need to use POST but what would be the request structure?

All working for me, for now, is the simplest GET:

http://myip:8123/api/?api_password=mypassword

Thanks for your time and patience.

Have a look here:

https://home-assistant.io/developers/rest_api/#post-apiservicesltdomainltservice

For domain and service put in homeassistant and turn_on.

See in the UI -> developer tools -> services + states

It's nice to be important but it's more important to be nice.

I added a couple examples [1] to the REST API docs. This should get you started.

I'm looking for more or less the same exact thing only to create a simple scene controller interface that can run on my phone and Pebble Watch via PebbleTasker plugin.  I stumbled on this repo which may or may not be deprecated by now- https://github.com/balloob/home-assistant-android-tasker and by loading up the XML file I was even able to find various API Call Service tasks already set up. For example there's a task called "API Call Service" with light/turn_on under Parameter 1 (%par1). Would I be able to use this template to make service calls to trigger individual scenes?  I can see scene/turn_on is available as a service but I don't see anything about how to trigger individual scenes in the service data fields.  Could I simply just add each scenes' entity_id into Parameter 2(%par2)?

A user in an earlier thread also mentioned using the RestTask plugin which I havent tried...
