EnOcean radio 868 MHz via TCM515, coupled to a freely programmable ESP32-C6 – serial interface on the host via USB, or WiFi and Bluetooth instead.
Now with the ESP32-C6: Wi-Fi 6 (802.11ax, 2.4 GHz), Bluetooth 5 LE and an IEEE 802.15.4 radio for Thread and Zigbee.
Free firmware, flashed in the browser at install.busware.de/EUL/: a transparent USB-serial emulation, or the cdc2net bridge that carries the EnOcean telegrams over TCP so the stick can sit where the radio coverage is, not where the host is.
Ethernet extension (option): the W5500 extension connects the stick by cable instead of Wi-Fi; with PoE it takes network and power over that one cable (IEEE 802.3af, Class 0; RT9400 PoE module with 36–57 V input, so passive 24 V PoE is not enough). Both variants are selected as an option above – they need the larger “plastic for Ethernet” enclosure.
Antenna: the antenna socket is RP-SMA (reverse polarity) – a plain SMA antenna does not fit; all antenna options above do. Without an antenna there is no EnOcean reception. For EU radio approval, the EnOcean TCM 515 user manual (v1.22, section 12.1) names at most 0 dBd antenna gain, i.e. about 2.15 dBi. Of the antennas offered, only the 2 dBi adhesive antenna stays within that; the +3 and +5 dBi antennas are above it.
Photos: some pictures show optional equipment – Ethernet/PoE extension, enclosure and antenna. These are selected and priced as options above; the base price covers the stick without them.
Note: We supply OEM hardware without firmware only – not a finished end product. Flashing the firmware and commissioning are the buyer's own responsibility.
