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 SimpleIndustry devices are fully integrated.

API 6 firmware

The SimpleMeter 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!

API 6 probe A and B

If you have a SimpleIndustry with dual external temperature probes, the firmware distinguishes between probe A and probe B. If you have the device on its back in front of you and the cabels are coming from the bottom, the cable on the left is probe A.
