after seeing few people interested in idea thought i'd put have made up.

made of relay board, 2 switches provide physical buttons boosting water , heating , 16x2 lcd display of heating status.

software in 2 parts java program turns relays on , off , web based frontend can control phone/tablet or pc , allows me set holiday times, schedules , groups.

features:
hardware
16x2 lcd display support
physical boost buttons

software
unlimited number of on/off times
independent water/heating controls
ability group schedules can activated/deactivated needed (great if work different shift patterns)

rough install instructions included @ above links, endeavour improve if interested in using this.
aware if messing heating controls use mains electricity - sure know doing , don't kill yourself.

have suggestions re: relay board controling combi boiler 'zerovolt' thermostat input. (basically when 2 inputs shorted boiler 'on', when disconnected boiler 'off'. don't think there current passing).

re: lcd board , boost buttons - not ifnd out off github website used/what connected to?

thanks

lcd hdd44780 , tutorial adafruit shows how wire them http://learn.adafruit.com/drive-a-16x2- ... i/overview. can buy them adafruit got mine off ebay few pounds.

switches simple momentary switches can maplins etc. first or second edition of magpi (free online) shows how can wire them up.

i'm not sure how 0 volt boilers work - i'm not sure believe 0 volts i'd have thought using 3v or 5v easier build circuit round. in theory if 0 volt hook single gpio pin perhaps zener , resistor boiler wires. still use relay or optoisolator make sure pi protected. again first few editions (i think 3) of magpi had how wire relay - dead easy - i'd use 240v 3a 1 in case not if cost large.
