I was able to add 2 iSS50 devices to HA with the 0.92.1 release with relative ease. Since there were two available to be configured, it was difficult to know which pairing code to use. It would be nice if the device ID was shown in the configurator dialog window.
Also, the default setting for the iSS50 is to show the temperature in Fahrenheit on the display. If you want it to be shown in Celsius, you need to connect to the device with the iHome Control app, change the setting, then remove the device from the app so that HA can pair with it.
The difficulty I have at the moment is the response lag when motion is detected. It can take upwards of 10+ seconds before HA response to motion being detected. It seems that motion is detected very quickly in the Home app on iOS. I’m not sure if it is a configuration issue in HA or the HomeKit Controller. Is there a polling frequency setting, if polling is being done?
