Hi, Thanks for your comments. I was wondering if anyone was actually reading this. I know it is Christmas in Europe, so everyone is visiting or away on vacation. I am on vacation, but I am playing with wires and sensors! I will know in a couple of days if I am still getting contact bounce. I may be ...

I still have problems with contact bounce. My counter was increasing faster than the meter itself. I have moved the waterproof box containing the DS2423 circuit closer to the meter and shortened the meter switch cable by about 3m. I am suspecting that the long switch cable was also a contributing fa...

So, it's pretty much done. I have written a quick Python script that calls digitemp to sample all sensors. I use cron to execute this script every minute. In the Python script, if the time is a multiple of 5 minutes I log the temperature data to a file (otherwise I discard it). I then convert the co...

Hi, Just a quick update. I pulled the wire under the house (yuk!) and reconnected my internal and external temperature sensors. I was able to attach the external temperature sensor to the box with the DS2423 counter in it, so the wiring is tidier now (the external sensor used to go into the house th...

Hello, Just to inspire people with my infectious enthusiasm I wanted to say I am nearly done with a water meter logger. I happened to be talking to a chap in the Water department of the local Council. I had recently had my water meter replaced and I asked if it had any instrument capability (since i...

Who pays for the meter to be changed? Here in New Zealand I think it's me. [:(]

Yes, but I already have a meter, provided by the electric company. I don't want to pay them to replace it, and they won't do it for free. At the moment my detector has cost approximately 2 Euro. I have used these components to verify that the idea works, so my next step is to build two 'final' desig...

Hi, I have the same problem. Here in New Zealand I have two meters. One is for the general supply to the house: lights, sockets, oven, etc. The other is for hot water and an electric storage heater, and is switched on at night by ripple control. I leave the hot water turned on all year, and the stor...
