Mobile data collectors
Innotas Elektronik GmbH offers mobile data collectors for reading data during "walk-in" or "walk-by" operation of end devices.

The end devices, such as EHKV (electrical heat cost allocators) or water meter attachments with wM-Bus radio option, transmit consumption data within the set time range at short intervals. Within this transmission window, the devices can then receive the data. Depending on the quality of the radio connection, reading is also possible without entering the building, e.g., from a vehicle. The receivers are designed to receive transmission protocols according to
Designed according to the wM-Bus standard, it is therefore also suitable for receiving data from end devices of other manufacturers using this radio standard.

wM-BUS Gateway
The wM-Bus Gateway receives wireless M-Bus protocols in T/C/S mode, filters them as needed, stores them temporarily, and sends them to a server via an IP connection.

The gateway does not have a mobile data connection. It only uses existing networks. The gateway is particularly suitable for stationary reception of wM-BUS protocols using an existing internet connection. Internet routers are usually already in place. In most cases, no changes need to be made to the router settings.
Simply plug the gateway into the router's USB port (optionally with a USB power supply) and connect it to the router with a network cable.

The gateway can optionally be parameterized via a website, USB interface or via the wM-BUS gateway server.
The received wM-BUS protocols can be pre-filtered in the device by manufacturer, medium code and/or by individual IDs.
The gateway sends the received and filtered data to the server either immediately, hourly, daily, or monthly.
The free "wM-BUS to TCP Gateway Server" can be used as the server, or an application developed by the user.
