Does the TAP Kiln Control Mobile app connect directly to the TAP Controller, or does it connect to a separate server first?
TAP Controllers connect directly to the TAP Kiln Control Mobile app through a secure SDS Industries server.
Your TAP Controllers connects to an SDS Industries server. The TAP Kiln Control Mobile app connects to the same SDS Industries server.
The database on the server is updated with data from your controller. The server then sends data to the TAP Kiln Control Mobile app, when requested.
The server also transmits commands to the TAP Controller, when directed through the TAP Kiln Control Mobile app. Your TAP controller is not accessible through a local network by navigating to the kiln’s IP address, meaning you don't have to worry about someone hijacking your kiln!
