The parts list is intended for one beehive. However, further sensors can be connected flexibly. The connected sensors can then be configured in maintenance mode.
Plug n’ Play and optional upgradeability
Not all sensors need to be purchased and connected! These can be added at any time. The system also runs if, for example, only one temperature sensor is connected. Therefore, the BME680 or other sensors can only be ordered later if the system is already working.
WLAN at the apiary?
If you have a WLAN network with internet access within reach of your apiary, you don’t need to buy a surf stick. The HoneyPi can log into an existing WLAN.
Electricity at the apiary?
If you have a permanent power supply at your apiary you can also buy the latest Raspberry Pi 3B+, because it has the best performance and can be used as a craft computer for something else.

Parts list for the secondary unit (ESP8266 or ESP32)
Update: We won’t have the secondary units so soon, because we are still developing the main unit further. But since we are Open-Source and someone else could do that, I don’t want to exclude it of course 😉
Info on the secondary unit : In addition to the main unit, there should be several secondary units. These can send their measurement data to the main unit via a common WLAN signal. The measurement data is then sent from the main unit and the surf stick connected to it to the Internet. This structure was chosen because the boards required for the auxiliary units are much cheaper and thus the price for each additional connected apiary is kept very reasonable. In the first version of HoneyPi the secondary units are not yet integrated. They will be supported in a future version. The whole should be optional retrofittable .
