AWS IoT SiteWise vs ThingSpeak

AWS IoT SiteWise is a managed service for collecting, storing, organizing, and monitoring industrial equipment data. Asset models structure information at enterprise, site, area, and machine levels. SiteWise Edge runs on local Linux or Microsoft Windows Server devices, gathering and processing data before sending it to AWS Cloud. It supports OPC-UA, MQTT, and partner protocols, and can transfer data to Amazon S3, AWS IoT SiteWise, AWS IoT Core, Amazon Timestream, and Amazon Kinesis. Storage includes hot and warm tiers plus a customer-managed cold tier using Amazon S3. The service offers real-time stream processing, custom dashboards, SQL querying, anomaly detection, and machine-learning tools. Internet communication uses TLS, with cloud transfer over MQTT or HTTPS; AWS KMS customer-managed keys can encrypt specified cloud values. The free Data Collection Pack transfers industrial data, while the Data Processing Pack costs $200 a month per active gateway. Broader SiteWise usage is paid with no listed price.

ThingSpeak is a cloud IoT analytics platform for collecting, visualizing and analyzing live data streams. Devices can send data through REST or MQTT APIs, and listed libraries support Arduino, ESP8266, ESP32, Particle and Raspberry Pi. Each channel stores up to eight fields, with data private by default and an option to make channels public. Users can run scheduled MATLAB code hosted by ThingSpeak without a separate MATLAB license. React and TimeControl apps support responses to channel conditions and scheduled computations. The platform supports near-real-time stream processing, custom dashboards and machine learning tools. MathWorks describes its uses as IoT prototyping, proof-of-concept systems and hosted production for small- to medium-sized systems. The Free plan is free for non-commercial use, with four channels, three million messages per year and a 15-second update interval. MATLAB code execution is limited to 20 seconds for free users; TimeControl cannot schedule MATLAB Analysis more often than every five minutes, and channel visualizations update after ten minutes. Platforms listed are API and web.
