After buying the valves last week, we started looking for some of the other things needed for automating the house.
The next things are

  1. Flow sensors – to measure how much water the motorised valve are letting through.
  2. Servo motors – To control how much air is supplied/extracted from each room.
  3. Push button switches – Needed for control panels

I actually used Alibaba’s request for quote to get prices for the flow sensors and received 10 quotes from $5 to $1.79 each. After looking at a few and asking for shipping costs a settled on a supplier. Luckily they were also able to supply the Servo’s and Samples of  various switches at a good price. This time the order was just under $500 including $160 of shipping.

We now have to wait for the 2 order to arrive and then we will have to pay import duty and VAT.
