When ordering the needed hardware new possibilities came to mind, as they so often do when you are browsing catalogs of companies selling cool gadgets…
The first version of the 1-wire network will look something like this, possibly with some of the sensors furthest away from the server installed at a later time. Some of these sensors are after all pretty expensive (just the humidity sensor, HIH-4000-001, got it from Digikey, that is attached to the DS2438 AD converter cost around €20). Getting the all the cables in place have also turned out to be a bit tricky, the tubing in the walls back in –65 just weren’t made with cat-6 networks, phone lines and 1-wire networks in mind…
The Linux server will run either temploggerd and owfs (if I can get it to work on the small Bubba Linux server that I am using, so far it compiles ok but doesn’t seem to respond properly to the sensors), or thermd.
I verified thermd runs (it does work as expected but it takes 15-20 seconds or so to update the graphs) on the Bubba server as long as you install the perl runtimes and quite a few Perl packages, but as owfs offers a better client-server approach it would be the preferred solution.
Hello from Canada. I have been looking for a way to monitor my own heating and control requirements for an older home as well. I have been thinking about using the HA7Net, but wasn’t sure if there are other options, economically and/or easily adaptable.
Thank you
Gerry
Hi Gerry,
The HA7Net is a bit pricey but considering it saved me both quite a few hours of software configuration, as well as buying a separate 1-wire hub (which aren’t cheap) I’d say it is worth it.
