I am setting up a Vera controlled system in my warehouse with about 16 different Trane tstat, but I have no switches or lamp modules, or anything other than Trane tstats. Are there any issues I need to be concerned about?
The Trane Tstat will act as part of the z-wave mesh and thus “talk” to each other. You will still have the distance issue if they are too far apart or trying to go through metal or concrete walls. Most of us have solved distance issues using either plug in dimmer or appliance modules strategically placed to enable the z-wave mesh. As for getting the signal through walls in a warehouse … experimentation will be your friend.
Thanks. I thought so but wanted to confirm. I will definitely need some modules for the distance issue, but that shouldn’t be a problem.
How many sq ft is your warehouse? Are the thermostats located evenly through out building? What kind of construction are you talking about?
90,000. It’s big. It’s open (no fixed walls), but aisles of shelving and pallet racks filled with metal parts. Most of my tstats are in 2 lines about 60 feet apart, with spacing about 30-40 feet between tstats. The issue arises between the 2 lines. I think a few strategically placed lamp modules might do the trick.
Is Vera in the center of this topology?
No. It’s at the end of one of the “lines”. In order to put it in the center of the topology I would have to put it near the ceiling, which would make accessing it quite a problem if I have to include or exclude anything.

If I remember correctly, Z-Wave routing is limited to “4 hops”, and even that’s probably dodgy…
If true, then Vera cannot be more than 4-hops (and preferably less) than the farthest away T-Stat. Of course, obstructions being what they are, the 4-hops probably aren’t the ones you’d think they’d be 
I see. It may be hard to reach the t-stats farther away, as it would require the signal to ‘skip’ intermediate t-stats, so a 60-80 feet ‘hop’, as the number of hops is limited, as @guessed pointed out also.
It appears (judging by how manual routing is provisioned) that you can have a maximum of 4 intermediate nodes; which would make it 5 hops total. For example: Vera > t-stat #1 > t-stat #3 > t-stat #5> t-stat #6 > t-stat #8, to get from Vera to t-stat #8.
Interesting. I didn’t know there was a hop limitation. I may have to hardwire another Vera somewhere down the line. What would be the best way to do so? Run them independently, or somehow chain together?
