Should I choose the Power G sensor over the IQ one because of it’s range or will both likely work about the same? Or do I need to figure out a way to get the standard door sensor (not recessed) to work on a recessed door?
A metal door will affect any RF signals, both PowerG and IQ would be hit, so range isn’t necessarily a question. Generally speaking, if you can, use a surface contact for a metal door. If you cannot, try using the recessed sensor in the frame and the magnet in the door. Does the sensor close and report reliably?
I read this thread but wasn’t totally sure what the turning off in case of fire setting would fall under: ADC T40K-HD vs Others - #2 by tyler
Fire safety rules are rule based automation triggers which are compatible with Z-wave thermostats. They are not supported on ecobee or Nest.
The terminals in our current one are W, RH, RC, G, and Y so it appears the ADC-T40K-HD will work based on these guides however I can’t find anything for the ADC-T2000-RC thus far to confirm.
Those are standard terminals and would be compatible with either the T40K or T2000. The T40K is a newer model which requires the C wire for 24VAC power. If you do not have a C wire connected you would need to run one to use the T40K.
It is recommended to use one anyway, but the T2000 can operate without it.
