A low cost WiFi adapter for the EmonTx V3, it can be used to post data to emoncms.org or other emoncms server directly from an EmonTx without a separate base-station.
Important: due to the increased power consumption from the WiFi module the emonTx must be powered by a DC 5V power supply (mini USB) in conjunction with a AC-AC voltage sensor adaptor.
