Seems to work well, they can use the area for decoration; battery operated candles and such if the cover is unscrewed but otherwise it's made to look clean, fresh and nice but not to be used. 

This timer does not need a neutral, but it does use a battery; on the one I had 10+ years ago, it took one AAA, which would last about a year.I am not affiliated with any companies mentioned.

Only once in the past 3-4 years was it an actual problem with the HVAC system (a battery had died in a remote sensor).If you are handy with numbers, you can calculate the incremental costs associated with keeping a space of X sq ft one degree at a certain temperature.  

Since the beginning of 2016, I've completed BP's beginner guide book and video modules along with side reading from other books and podcasts.

People don't change them regularly in the homes they own - they certainly aren't going to take care of it in a rental.Change the batteries in the smoke detectors twice a year when the clocks change - another thing that renters typically won't remember to do. 

I've got a solar provider that is self install that per panel it's is around $350/installed, plus costs of electrician and battery units.

Wired are best and the ones with 10 year batteries are second best.

They will be happy to arrange a demo on a variety of their modules available.Hope this helps.

Being extroverted means that you get energy from being around others.You can be very successful as an introvert, but you will need to make sure you get enough alone time to recharge your batteries.

I’m changing batteries in the smoke detectors and CO detectors, changing the air filter, looking at the backyard landscaping (which is on a watering system).
