Thanks for pointing out my timing logic flaw.  I adjusted the timing there and added two flags to (presumably) limit the duplicate UPB commands being sent.  Testing the code now with the furnace.  Ordered a UPB fan speed control to add to the mix.   54. EVERY 2 MINUTES AND IF Living Room SYSTEM...

Given the particularly cold weather in recent days I decided I should automate the fresh Outside Air fan that warms outside air through a heat recovery ventilator unit, then into the return plenum of the furnace.  I found that temperatures below 0 are low enough that the HRV is unable to preheat...

DELInstallations-   What are your thoughts on the Honeywell iGSMV4G as a solution for Brett?  Presumably that option does not violate the UL approval.  Does  the Honeywell Vista 21iP incorporate all of the functionality of the iGSMV4G plus a Vista 20p panel?  Given the age of my Vista 20P I was...

I was quite annoyed to find that my FiOS phone line kept specifically to support our Vista 20P panel's dialer was down without a "Comm Failure" indication last spring due to this "voltage there but no dial tone" issue. With only a weekly residential self test it was pure luck that I discovered...

Try connecting the toner between different conductors or to just one conductor-  if the far end is shorted toning doesn't work as well...  I have been known to coil wires at "known" locations in ceilings and walls for future use.  Remembering those locations can be a challenge though without a...

I continue to see occasional large spikes in the data.  I did replace one of the problematic HAI sensors which decreased the problem, but it does still show drops to zero or spikes to high values.     Is anyone else seeing this sort of problem?  Perhaps I just have a batch of faulty sensors.    ...

Is there any update on when we can expect to see more granular control of Russound zone volume controlled through Haiku Helper?  I recall mention a year or so ago that the current 0/25/50/100% options would be expanded.

Thanks Maksim-  thanks for your assistance.  For anyone who may be interested this is my code:     //Last updated May 15, 2014 // var ZoneTimerPorchPIR = null; var ZoneTimerDoorbell = null;   function onAreaArm(area) { //Pause iTunes when alarm system is armed    ...

I have set up Haiku Helper to push notifications to my iPhone whenever there is motion detected from the perimeter detectors on my Omni Pro II.  Now that the weather is warm I would like to add code to limit these notifications to be sent only when the OPII is armed-  otherwise yard work leads...

My solution to this problem has been to run dedicated lines to critical locations over the years and have one big (2kw) UPS handling all of those loads.  12/2 with a nice red receptacle at each location.  That one Smart UPS has a Web/SNMP board installed.  Those boards are readily available on...

My control solution for hot water boosters has been much simpler-  time of day.  Turn on the circulator pump before the typical morning/evening shower and bathroom activities so the water is already hot when needed.  Turn it off over night and when the house status is unoccupied.  Add override...

If you can connect to the expansion panel with standard RS-485 you could run MM fiber through the conduit without any induced current issues. http://www.ebay.com/itm/380764743643 http://www.ebay.com/itm/190977587612

Is the LV/HV restriction based on the voltage running through the wire or the voltage RATING of the insulation?  I know it is a special case, but the cable bundles run to elevator cars have a range of voltages from 120v for lights and door motors to low voltage for call buttons and displays...

I would expect the problem to be noise from the control side, not the high current heaters and motors.  That was my experience with a furnace:  the variable speed blower control put all sorts of noise onto the AC wiring.  Look at the circuit and see if there is a way to isolate and filter the...
