The inability of the electricity company to read the meter persists - every reading so far has been accompanied by a phone call asking me to re-read it! The 'smartness' is not enough to enable automatic reading but enough to confuse the people.
The leak on the ground circuit persists - at about 0.25l per week. No-one seems to have any suggestions here and the leak is probably too small to be traced, even if it is visible.
The house monitoring system (at http://www.welserver.com/WEL0412/ ) continues to be extended, now with a rainfall monitor. This is an adapted version of the Oregon unit, with an extra magnetic reed relay (from Maplin) added so that a signal is generated from the WEL's pulse inputs as well as the Oregon readout (which is not compatible). The WEL detects the switch closure and only connection is required. The sensor is a tipping unit with alternate emptying reservoirs, rather like a Japanese fountain, and only detects whole mm.
