The device can be used in 3 different modes depending on the settings:
– Call and SMS notification when a contact input event occurs
– Relay control with free phone call
– Temperature range supervision in remote locations
The device makes an alarm call and/or sends a text message to up to 4 phone numbers. The relay output can be controlled from up to 8 phone numbers with caller ID authorisation.
It is possible to grant temporary control rights up to a validity date for up to 4 phone numbers. This date can also be easily changed by SMS, so that e.g. the AIRBNB electronic door key can be easily entered and deleted. In a configuration without caller ID, an unlimited number of users can control the output relay.
