We think an AWS Greengrass core on an RPI4 could communicate to the client with MQTT or a local webserver with a client web interface.Īny thoughts would be much appreciated. We are primarily Python programmers, so PyQt or Kivy are options for us, but we have heard good things about React Native, Flutter, Xamarin, and others. Question: We want to develop a cross-platform client to run on Windows, Mac, Android, IOS, and possibly Linux. We may use the AWS GreenGrasss edge computing solution and either MQTT or HTML for that function. The crew might have an Android or IoS phone or a Windows or macOS PC to receive alerts and interact with sensors. When the boat is offshore, the captain and crew still need normal and emergency alerts and real-time sensor information. When the boat has internet, we interact with AWS cloud using lambda and Amazon DynamoDB. The IoT devices have sensors all over the boat for engine oil pressure, position, water depth, fuel level, crew location, etc. We are developing an AWS IoT app for large boats.
