yessssms platform is using the Austrian mobile operator Yesss.at and others to send SMS via their web-site.
Currently some MVNOs (mobile virtual network operators), in the A1 network, that use the kontomanager.at interface work. These are currently (as of version 0.4.0 of YesssSMS):
You can send to any number, but your phone number will appear as sender.
To enable SMS notifications in your installation, add the following to your
# Example configuration.yaml entry notify: - name: NOTIFIER_NAME platform: yessssms username: YOUR_PHONE_NUMBER password: YOUR_PASSWORD recipient: PHONE_NUMBER_TO_NOTIFY
The optional parameter name allows multiple notifiers to be created. The notifier will bind to the service notify.NOTIFIER_NAME.
This is your login name (usually your phone number, but in some cases it could be your e-mail). Veryfy that you can use your credentials on the Yesss.at website.
For an alternative provider you would set the
provider option. An example configuration for the
educom provider with SMS to yourself would be:
# Example configuration.yaml entry notify: - name: sms_to_self platform: yessssms username: "+436641234567" password: tops3cr3tpass0rd recipient: "+436641234567" provider: educom
Home Assistant will check your credentials on startup. Check the logs for errors. If the login credentials are not valid, re-check the credentials and restart Home Assistant.
