This may be an academic question for the moment, however a customer is keen to have an energy meter approx 100m (and several walls) away from the CCGX and installation. The standard zigbee may not be enough; are there any known supported zigbee repeaters that might work for this purpose or a longer range, higher power unit? Alternatively would the ET112 RS485 signal support an RS485 wireless bridge? Thanks
Yes, their are many options, depending on the Country in which it will be used. As you stated these are "Repeaters", so they don't do anything to the signal. They just take a standard RS485 differential signal and transmit it, by radio, to another place.
You will need two units, one for each end. An example is a Digi International product, using the 900Mhz band. XM-M92-4P-UA-ND Digi RS485 Transceiver. They are about $160.00 USD each. Their indoor range is 10 Kbps: up to 2000 ft (610 m); 200 Kbps: up to 1000 ft (305 m). The outdoor range is much greater.

Thanks for your response Pat. We are trying the regular Zigbee pair from Victron first of all, making use of a hard wired cable to bring the transmitter closer.
However the lack of instructions for the Zigbees is causing issues. Does anyone know the setup instructions, specifically what the buttons actually do and when to use them? Even with both units side by side struggling to get them to pair.
Hi,
Have anyone tried other RS485 transceivers? I have tried DoRji RS485 transceivers, they are priced a lot better. Although I can read the modbus register remotely the VenusGX doesn't seem to pick up the meter.
