I took some time to work on the house 1-wire network today.. and blew up
the serial to 1-wire interface in the process. I think there is a voltage
difference between house ground (water pipes) and 1-wire ground and I touched
a metal part of the 1-wire counter I was going to use for the electricity
counting to a water pipe hiding behind another pipe when I was trying to
test whether it responded to the led in the electricity meter. So, still
no success on measuring electricity and no new
house temperature readings either.
I did put in an extension of the 1-wire network from the attic to the
cupboard beneath the stairs where the electricity meter lives. I used the
'isdn' sockets on the end of the long 1-wire connection so as a side-effect
I moved one temperature sensor from the top of the server to the 'wine rack'
area and updated the sensors page. It is a different location temperature-wise
so I started new statistics for this sensor. I also looked at options for
placing a temperature sensor in the living room. The cable to the thermostat
is thoroughly cemented in so I can't place a wire alongside that cable. I'll
probably use the hole for an extra television-coax cable to get a wire for
a temperature sensor from the crawlspace to the living room.
I already ordered a replacement serial 1-wire interface. I hope that is the
only component that was damaged.
