Apartment Intercom vs KGateway

Product features: ◆ Support 200 sets of numbers, each number can be set in the time period to control the relay to open the door. ◆ A relay output is used to control to open the door, connected when there is the number of incoming users , And it will automatically disconnect at set time. ◆ After a user calls to control to open the door, it can send SMS to the user about its action. ◆ 000~999 seconds, we can control the relay closing time, 000 indicates: the relay is closed for 0.5 seconds then disconnected. 999 indicates: the relay can be closed until the same number incomes again then disconnected. ◆ SMS commands can be used to query the current state of the host (relay status and GSM signal value). ◆ SMS can be regularly uploaded for the current state of the host to the first user number. ◆ Use the clock on the module, each time the host sends SMS to itself to correct the time.

KGateway is a configuration app, through which you can configure the BLE/Wi-Fi gateway launched by KKM. This app supports configuration of the following parameters: 1. Wi-Fi connection information. 2. BLE scan parameters, filter parameters. 3. HTTP or MQTT server information connected by the gateway. After provision by the app, the gateway(BLE/Wi-Fi) can connect the BLE Beacon/Sensor devices, and can report the sensor data from Beacon/Sensor devices to the cloud. Why does this app need location permission? Because the app needs to scan the SSID information of the KGateway when configuring the KGateway for the first time, and the location permission is required for IOS to scan the Wi-Fi SSID information. Why does this app use the HTTP not HTTPs protocol? This app only uses HTTP protocol to connect to the KGatway(WiFI-BLE gateway) for provision. Because the KGateway's internal resources are limited, the device only supports the HTTP protocol. In addition, because the app will only perform provisioning when the KGateway is used for the first time, and the app and the KGateway device must be under the same Wi-Fi router during provisioning, the security risk of using the HTTP protocol for Provisioning is controllable.
