1.3 Wireless Interfaces
Engelmann offers the following radio interfaces:
-
wireless M-Bus interface EN 13757-3, -4 (see chapter 1.3.1)
-
LoRaWAN communication interface (see chapter 1.3.2)
General information about the radio interface:
Installation of radio components between or behind heating pipes, or the presence
of other bulky metallic obstacles directly over or in front of the housing must be
avoided.
The transmission quality (range, telegram processing) of radio components can be
negatively influenced by instruments or equipment with electromagnetic emissions, such as telephones
(particularly LTE mobile radio standard), wi-fi routers, baby monitors, remote control units, electric motors, etc.
In addition, the construction of the building has a strong influence on the transmission range and coverage.
Furthermore, when using installation boxes (substations) they must be equipped with non-metallic covers or doors.
The factory-setting of the clock in the meter is standard (winter) Central European Time (GMT +1). There is no
automatic changeover to daylight savings (summer) time.
The radio function is deactivated upon delivery (factory-setting). See chapter 1.3.1.3 & 1.3.2.3 regarding the
activation of the radio interface.
1.3.1 Radio interface wireless M-Bus EN 13757-3, -4 (optional)
The radio interface transmits meter data (absolute values).
