Question: Can you recommend a cloud-based IoT analytics service that supports multiple hardware platforms?

ThingSpeak is a powerful IoT analytics service that supports a range of hardware, including Arduino, Raspberry Pi and ESP8266/ESP32 Wi-Fi modules. You can capture and analyze real-time data streams, and it's got features like private and public channels, RESTful and MQTT programming interfaces and the ability to trigger actions based on patterns in your data. It's good for IoT projects, research and real-world applications.

Another big contender is Cloud IoT Core from Google. The service securely connects, manages and ingests data from devices around the world on Google Cloud infrastructure. It's got enterprise-scale AI for IoT data processing and integration with other Google Cloud services like AI and ML for more advanced analysis and automation. It's good for many industries and use cases, including supply chain optimization and manufacturing process control.

Viam is a cloud-based service that makes it easier to build, monitor and manage smart machines. It can collect real-time and historical telemetry data, use AI and perform predictive fleet maintenance. Viam's open-source design means it can run on any hardware, so it's good for many industries and use cases, including predictive maintenance and environmental monitoring.
