The Microsoft Azure service called IoT Hub is now also available in West-Europe for a couple of weeks. To be precise, it’s available as a service in East Asia, East US, North Europe, Southeast Asia, West Europe and West US.
It is good to know that there are basically three flavours available: Free, S1 standard and S2 standard. The free edition only support one, uniquely registered, device which can send eight thousand messages a day. The other versions support 400.ooo messages to six million messages a day. If you want to support more devices/messages, please contact Microsoft 🙂
Note: You can have only one Free IoT Hub in your Azure subscription. And turning a S1 IoT Hub into the free one is not possible.
Keep in mind that messages have a certain size. If the actual size of a single message is bigger than 0.5KB (free version) or 4KB (S1 or S2) it will be counted as multiple messages.
