Texts from your smart home

Home Assistant can call REST APIs with the built-in rest_command integration, so any automation can send an SMS through SimGate — no add-on required.

Define the command once in configuration.yaml, then call it from any automation as a service.

Define a rest_command

json
1
rest_command:
2
  simgate_sms:
3
    url: "https://api.simgate.app/v1/sms/send"
4
    method: POST
5
    headers:
6
      x-api-key: "YOUR_API_KEY"
7
      Content-Type: "application/json"
8
    payload: >-

      {"deviceId":"android-5q15b182f2704gbz",
10
       "phoneNumber":"+1234567890",
11
       "message":"{{ message }}"}

Add to configuration.yaml (shown as YAML).

Use it in an automation

1
Add the rest_command

Paste the config above and restart Home Assistant.

In an automation action, call rest_command.simgate_sms with a message.

3
Trigger on anything

Sensors, schedules, presence — any Home Assistant trigger can now text you.

Frequently asked questions

Do I need an add-on?

No — the core rest_command integration is enough to call SimGate.

Can I send to different numbers per automation?

Yes — parameterize phoneNumber in the payload the same way as message, and pass it when you call the service.
