The description says 2-year battery life... is that what you have found? (plan on using it exclusively via z-wave). I don't have a spare 24V line without running another wire to the furnace (a pain).

My unit has AA batteries in it, so battery life depends on what quality of battery you buy. I got about a year and a bit because I put in Duracell Coppertop. Maybe the new Lithium will be better for longevity.

I didn't have a C wire when I installed my thermostat. From what I can figure, the C wire is used for power, and the batteries will kick in when the power goes out. My previous thermostat was programmable with batteries. The batteries lasted a long time in that thermostat.You can set the temperature range where you want and leave it. For some reason, my Vera 3 set up 3 thermostats. 2 are like ghost thermostats, and 1 is the real one. But, I can access and control that thermostat from anywhere. I also set the poling time lower so that it checks the temperature on the thermostat more often. I think I set it at 1/2 hour. I didn't have a C wire when I installed my thermostat.

Hi Magnvs, Your assumption is correct. This is one of my favorite products within my zwave network. The energy monitoring feature is excellent and when you pick up the unit you can tell you have a solid, well built product in your hands. If I can be of further help let me know. Take care.

No problems. I have two of these paired with a Vera 3 and the batteries last 6-8 months on each one. My friend got one and had problems with the batteries, he called Schlage and it turned out it wasn't paired correctly with the Vera, they excluded and re-included it to the z-wave network and the problem went away.

You can run this without a 24VDC source. I only have heat, you do not need air conditioning in the U.P., so I only needed three wires. I do all of the control in my VeraLite so I do not use the features of the thermostat. I find that the temperature signal from the thermostat is not reliable in the VeraLite but the system controls perfectly so I do not care. Batteries last six months or so.

I own one of these, and can't answer this question with technical accuracy. I can however answer it with experience. In sub zero temps outside, the inducer motor on my furnace failed the other day. I had to kill power to the furnace for 4 or 5 hours while I found a replacement part and installed it. The unit is completely powered by the furnace so it was without power the entire time. The thermostat was not an issue. It had been without power for at least 4 hours and once power was restored it still retained the router settings and I did not have to reprogram it. I believe all the settings are stored on the Website and all the thermostat needs to retain is the Router setup. It appears to store the router info in the BIOS. Hope this helps. I have only used this for a couple months, but so far it is perfect.

Hi John, sorry for the delay in my response. To be honest I don't know. I can say it is a well made unit and has worked perfectly with my Smartthings hub. If I were you I would get one and monitor the voltage drop for a couple of months. You should be able to make a good guess of how long it will last you. My device is located on my front door. I enter and exit my house usually once per day so I'm sure I'll have much longer battery life than say someone who mounts this sensor on their bedroom or office door.

Well, mine has lasted since I bought the collar, about six months ago, but it's trivial in any case to put a new one it. The battery is just a standard 9-volt (such as you use in your smoke alarm).

I've been testing mine out recently - I run for about 2hours, 2hours 15 mins. It usually lasts 2 such days - so 4- 4 1/2 hours- which is quite disappointing. I have a feeling indoor battery life maybe slightly better. I was looking for the "rated" battery like myself. Would be nicer if it went a week without charge.

I just hooked mine up yesterday, and so far so good as far as tuning, static, signal strength etc... I'm interested in battery life because I have mine set up about 50 feet from the transmitter, on the back side of my pool where I have my grills and hammock. It used to be that I had to crank up the speakers on the patio in order to hear anything out past the pool. This naturally caused issues with my wife, especially when Saxon, Rush, Judas Priest etc. "shuffled" into play.I just hope that I don't have to replace batteries every week!

Phillyphil, the description of "3 to 5 years" doesn't mean that it has that amount of electricity supplied. This battery is very much like a car battery. You can use some, or all, of it's electricity when your power goes out and when the power comes back on it recharges back up. It will live this way for 3 to 5 years. When it finally dies, it will need to be replaced. Engineer David

Yes, Thats how I always used it. This battery will die after a couple of years. Might that be your problem?

Depends on your usage. .. if you use 2 hours daily maybe can lasts for year or 2 ... but issue with battery more rechargeable batteries can use 2 hour continues but as you cant store for 2 days even every time you need use you need recharge batteries its painful for me... and normal batteries will cost you each time and not usage long on heating time. .. soo i use my normal solder more rather then this. .. but works ok all... but not worth to buy coz something you feel irritate to use its worthless... hope my answer will help you some.. thanks

Mine has gone through an outage of about 12 hours and the unit and returned to the schedule I had programmed. I am not sure how long you mean by 'prolonged'. I also have a wifi programmable Lennox wifi thermostate. I am replacing it with the Honeywell wheich is far superior. The clock is internet set so quite accurate.

I am using this for alarm system backup (line power failure) so it sees infrequent use. Still near 12v after a year.It will probably go 3 years but I'll swap it @ 11 volts-open.

I have two multi-sensors in service since Feb 20, 2014. Both currently report battery level at 75%. Note they have been at this level for a while. At this rate, I am expecting a 9-12 month life span.

I'm guessing battery life would be dependent on adverse weather it's subjected to. If using within a garage where cold temperatures could creep in, I'd guess much lower than 3 years, maybe less than a year. But who knows. I'd imagine, though, that it shouldn't be so short that it's a hindrance.
