Check out the SunStat Pro 500670 - it has a low voltage home automation input.  Note that this unit's (or any other manufacturer's) thermistor/temp sensor will very likely be incompatible with your existing thermostat.  So you'll need to replace the temp sensor which can be very problematic with...

Here is some Ruby code from an M1 Siri project:   # Append checksum to M1 message def m1_add_checksum(message)   # calc the checksum   chk = 0   message.each_byte do |b|     chk = (chk + b ) & 0xff   end   # two's compliment   chk = 0x100 - chk   # add leading zero   #  if chk < 16   #   ...

  At first glance you might think so, but actually the air returned to your interior would be cooled to 74 degrees (given your scenario).  This is because the air flows in opposite directions across the heat exchanger surface.  If it flowed in the same direction (a very poor design) then, yes...

  Done!  It's available on github.com at https://github.com/mghan/siriproxy-m1   Mike

I've expanded on the excellent SiriProxy work of elvisimprsntr (and others) and wrote a direct-to-Elk M1 plug-in for the Raspberry Pi. It supports lighting, tasks, thermostats, temp sensors etc. I'm happy to share, just don't know how to push it up to github. Mike

Yes, it seems likely the XSLZW it the culprit. Replacing it may be the path of least resistance. Thanks for the feedback, Mike

Hello all, I have an all Leviton Vizia RF+ system with 50+ dimmers, switches, scene controllers, Trane Tstat, eKeypad etc. My M1 (5.2.10 firmware) is equipped with the M1XSLZW (81.0.4) and VRCOP 3+ (updated to the Nov2012 firmware). Every week or two, I lose control of my ZWave network. I can...

No luck displaying counter (using Jimmy's method) on eKeypad. My counter does display fine on the physical keypad. Any ideas for eKeypad? TIA

Great summary. I have a similar setup (minus the locks). I'd also add that it's important to associate (using RF Installer) the VRCOP with any Thermostats (it's not selected by default). Have you made sense out of the 24 "buttons" in the VRCOP? The M1 seems to be able to control the...
