(firmware-overview)=
There are different firmwares for different flavours of appliances, both in terms of sensor coverage, and telemetry capabilities. We are enumerating both firmwares from our own pen, and from other open source projects.
This section enumerates and groups firmwares by origin, chronologically sorted in the order of appearance.
Collecting beehive sensor data since 2011. With the first »Hello, world« post in November 2011, and the most recent one in May 2023, you can see that Markus is surely one of the most avid and proficient data collectors, and inspired many others to start similar projects.
:::{seealso} He published many articles about his journey, and it is a pleasure to read all about the development progress in the bienenwaage and bienenwaage2 sections on his personal blog. :::

All systems conceived by Open Hive. Clemens Gruber reports about the development progress on his personal site at http://open-hive.org/. He pioneered low-cost scale platform designs based on aluminium bars.
:::{seealso} Clemens shared many resources about the development of a low-cost, aluminium scale platform, see Bee Scale Prototype 2, Open Hive Single Scale Bar, and Two-bars aluminium scale platform. :::

The sensor device will acquire measurement readings, and emit messages encoded with protocol for [ISM radio] telemetry. The gateway device receives it, and forwards it to the UART interface of the gateway machine.
:::{note} beradio-python will read this data, decodes the protocol, and publishes the decoded data to an [MQTT] bus topic. is running this firmware since February 2016. :::
