*Expand to 12 CT channels: Add a further 6 CT channels to the emonPi2 (Pi Zero 2W option only) or emonTx5 to monitor up to 12 circuits with an optional expansion board.

emonTx5 (available soon): A 6 channel* electricity monitoring node. Transmits data via 433MHz radio to an emonPi or emonBase. Great for expanding an emonPi2 monitoring setup where more CT inputs are required either in the same location or in a different part of the building.

emonTH2: A battery powered, wireless, room based temperature & humidity monitoring node. Transmits data via 433MHz radio to an emonBase or emonPi.

Heat metering: Plug in a M-BUS reader and Modbus reader to the emonPi2 USB ports to read from heat meters and other electricity meters for heat pump monitoring. See also pre-provisioned level 3 heat pump monitor bundle and our heatpumpmonitor.org initiative.

emonBase: A Raspberry Pi base-station that receives data sent from emonTx and emonTH radio nodes. Can be used instead of an emonPi2 where the installation favours locating these in different parts of a building.
