Yes, good point - I have a couple of HS serial device plugins :(

And not necessarily that easy, - or sometimes even possible for certain
devices... especially when a specific Homeseer plugin has been purchased
and configured just right for a serial device for which a simple conversion
to TCPIP just isn't available...

RS232 isn't going to go away completely for HA any time soon.... :-(

Serial ports dying isn't good :(

Yes, I had been thinking about moving to RS232 over Ethernet - seems a much
more attractive solution - shame it all adds up to a lot of cash though for
a number of devices.

I'll have a look tonight when I get home... - I can't remember any of the
details about it just now... I do remember I got it from eBay though....

The other thing I've noticed is that on my HA server (now a VM), the
virtual serial port drivers do occasionally "die" and the machine
completely loses contact with all its virtual serial ports... I don't
recall that being the case immediately after installation on a
"clean" XP build, - I definitely think it started happening some
time after I'd been using it without problems for a while, so the
likelihood is that some Windows update or other introduced an
instability... I've got round it by scheduling an automated reboot of the
VM every night at 04:00 which seems to keep it running pretty sweet. Very
occasionally, (and it really is quite rare nowadays), the drivers will
still die during the day, and only a reboot will fix it, but that only
seems to happen once in a blue moon....

As a matter of policy I'm therefore trying to get as much as possible of
the
RS232 kit attached to the HA Server transferred over to a TCPIP connection
wherever possible, so I've bought Comfort UCM_ETH daughterboards for the 2
UCMs currently connected via RS232, and as mentioned, I'll be seeking a
replacement for the Quasar temperature boards as well...

Paul,

Interested in your Ethernet-RS232 server box - what did you get?

I'm running all my servers on VMWare vCenter and thinking of moving my HA
Server over too - but the 12 serial ports are currently a sticking point.

Thanks,

Paul.

Can you tell me a little more about this item? - it's just reminded me that
I do need to do something about my temperature sensing solution... - I
previously used a couple of Quasar boards to support up to 8 DS1820s, but
they rely on RS232 port power... - when I virtualised my HA server I
implemented an Ethernet-RS232 server box to provide up to 8 serial ports
via the LAN... but the serial ports presented by that box don't have (or
don't have enough) power to run the Quasar boards, so I haven't had any
temperature sensing going on since I virtualised... I've been meaning to do
something about that for a fair while...

So, I already have a bunch of the 1-wire temp sensors kicking around... I'd
like to get them back into use... I need a solution that I can implement
pretty much out of the box... - if I haven't had time to even think about
this for nigh on a year, you can be sure I don't have time to be soldering
up my own boards and/or rolling my own code!

I want the solution to integrate with Homeseer...

I *need* the solution to NOT be dependent on serial ports to provide power!

I suppose one thing I could try to think about would be to modify the
Quasar boards to run on power from a separate wall-wart, - but see my
earlier comment about soldering!

Anyone got any thoughts / suggestions?

TIA

Paul G.

Hi Folks,

I've contacted a couple of people who expressed an interest in PCB's  &
connectors for 1-wire temp sensors.

Pictures from Kevin here: http://bit.ly/c5Rkxj

If anyone else is interested, please get in touch off list, I'd like to get
a parts order sent off in the next few days to get parts shipped out in
time for tinkering over the xmas holidays.

Cheers

Stuart
