Zigbee – This is the modern standard for wireless networking of various devices for your smart home. So that data protection is not neglected, we free the popular CC2531 stick from its proprietary firmware linked to an Asian cloud. You will receive the CC2531 stick from us ready-flashed with the well-known open-source firmware and, if desired, in a stylish housing as well as an external antenna.
- Slim and sophisticated 3D printing case
- LEDs remain visible, buttons remain operable
- Flash pins are protected
- Easy opening of the lid to reach the flash pins
- External antenna connection on request
- Through a professional execution of the connection, the range / LinkQuality is significantly increased
- USB extension cable on request, as direct connection to the base can limit the range
Please take a critical look at various other offers, e.g. on eBay, with external antenna connection. All offers that connect the inner conductor by means of a cable lack any shielding and result in a mismatch. The same applies to offers where the housing of the SMA connector is not soldered to the ground plane of the board!
If you buy cheap, you buy twice.
The following measured values of the signal strength (Linq Quality) should provide a rough orientation for the choice of the antenna. They were recorded under the same conditions and with USB extension cable.
|Folding antenna, small||44-55||52-63|
|Folding antenna, large||55-65||42-49|
When buying a Zigbee stick, make sure you have the right firmware. The firmware can only be flashed by additional hardware – therefore also note our free re-flash service. Our sticks are immediately usable with the current firmware – the following variants are available:
|Default||Coordinator||2021 11 15||Koenkk||Recommended for networks with 1-30 devices|
|Source_Routing||Coordinator||2021 11 16||Koenkk||Recommended for networks with more than 30 devices (Requires router in direct range)|
|3.0||Coordinator||2019 05 23||Koenkk||Beta version (not recommended for productive use!) for Zigbee 3.0, maximum 40 devices|
|Router-std||Router||2020 09 29||ptvo||If an existing network is to be expanded (more devices or range)|
You will find the necessary configuration steps for setting up in our 21-page manual PDF, which will be sent to you by mail shortly after receipt of payment. It covers the integration into the following systems based on a Raspberry Pi:
- openHAB 2
You will also get an overview of the Zigbee technology and the interaction of the software components used – so that you can understand what the individual Linux commands mean.
Fair: We are happy to update the firmware of Zigbee sticks purchased from us against payment of the postage costs – without additional fee!
