IOT Central is Microsoft’s low code, low effort, ease of use approach into the world of embedded projects. This is quite a demanding challenge, because real world problems tend to be complex and what can you do to make these simple in a tool?
Well, normally you start with defining an environment, to get rid at least of some of the parameters and thus reducing complexity. This is a valid approach, but for a tool/service vendor it carries the danger that the overlap of your defined environment to common real-world use cases of customers, is not large enough, or, as a worst case, even not existing.
Azure IOT Central, in the beginning, felt a bit like: great base features, but not enough to cover a complete project spectrum of demands.
Therefore, to me it was good for samples or a quick POC for a project. However, the IOT Central team kept improving steadily and so the product is getting more serious as we speak.
The newest update provides some very interesting features, like jobs that can be execute on devices (very important for device management), webhook improvements looking at identity management, device templates to support IOT Plug & Play as well as improvements on the dashboard.
At least for me enough new stuff to justify a closer and serious re-visiting look into IOT Central!
