First, what Zwave thermostats are compatible with the ISY 994i that I buy the zwave board for someday?

 

The reliability and the reviews of the smarthome and venstar units seem pretty bad. Reading review on a Honeywell zwave thermostat was all 5 star compared to as many 1 star as 5 star with the insteon capable thermostats.

 

I don't have a traditional furnace in this application at all. It's a from scratch set up and I'd like not to have to have 5 or 6 different things all connected to get control of this heat system through my ISY and therefore from my cell with Mobiconnect.

 

Hi arw01,

 

ISY994 with ZWave option has been tested with ZWave Honeywell as well as RCS thermostats.

 

With kind regards,

Michel

How far does the zwave typically go? Will we make it through 2 aluminum sided walls, or should I plan on some sort of relay set up or something to take zwave onto the powerline to get to the isy?

Hi Alan,

 

Max range for ZWave is about 200ft. Best practices for ZWave suggests 6 to 8 devices to make a complete mesh. There are very many cheap GE ZWave dimmers/appliances that you can use as your repeater/mesh.

 

With kind regards,
