# Janitza UMG, Siemens PAC 2200, neoom BEAAM

Part of the [compatibility overview](/integrations/compatibility), which lists every selectable Mains type.

* Janitza UMG: reads the float block from register 19000 (UMG 96RM, UMG 604
  and compatible). Total and per-phase power, currents and voltages.
* Siemens PAC 2200 (Modbus TCP variant, e.g. 7KM2200-2EA30-1JA1): from
  firmware 2.5.0 the station reads total and per-phase active power and
  currents via Modbus TCP (port 502, unit ID 1). Voltages are only used to
  check the register mapping and are not shown. Leave the meter's
  *Invert current* parameter at its default (no); the station converts the
  PAC's sign convention itself. Up to firmware 2.4.x the
  values are decoded incorrectly (readings around ±2 billion), so update
  the station before commissioning.
* Siemens PAC 2200, check after commissioning: when a charging session
  starts, the grid draw shown by the station must rise (or the feed-in
  fall) by roughly the charging power. If it moves the other way, the
  current transformers are mounted in reverse. On MID-certified units the
  direction cannot be inverted in the meter, so the wiring must be
  corrected.
* Siemens PAC 2200: the updated driver is still in its first field test.
  Contact eCharge support before planning a new installation with this
  type.
* neoom BEAAM: grid values from the gateway's Modbus TCP server.
* None of the three delivers battery values.
