SimplePack 3.0 and 4.0 Plus Introduction


The SimplePack 3.0/4.0 Plus is our universal IoT sensor that can cover over 50 use cases using different physical sensors and smart business logic of reporting data. The device comes in different versions that are tailored for different use cases.


You can find more technical information and also all available device versions in a datasheet we have prepared for device presentation.

Simple Hardware is not the IoT platform business and we are happy to support and list any platform supporting our devices. However, out of all the available platforms, we strongly recommend the IO Frog platform as SimplePack 3.0/4.0 Plus devices are fully integrated.

API 6 firmware

The SimplePack 3.0/4.0 Plus runs on the API 6 universal firmware (like all available Simple Hardware devices except the SimplePack 2.0). The firmware is rather complex and has a slight learning curve, so we suggest you start with this article:

HERE's the API 6 overview for beginners!

What's on the back of the device?

Every Simple HW device has a label on its back with important information. The information content can be customized:

What is Core?

When we produce some items for stock we produce hardware-wise the same hardware and we unlock the different functions/sensors via software - add-ons.

The SimplePack 4.0 Plus Core device contains a button, accelerometer, and magnetic switch functionality.

For manufacturing optimization, it is sometimes more efficient to produce a generic device that contains the above sensors/functions than to manufacture 3 separate batches. When we ship them, they are enabled with the functionality that the customer has requested/required.

If the order is larger (generally thousands) or we ship from the stock where we have the specific device in stock by chance, the devices with only the specific components are shipped.
