It might be a better idea to come up with ligament reasons to check the property such as scheduled repairs. ie: yearly furnace cleans on one date. replace the batteries in the smoke alarms on another trip, and one yearly apartment inspection for damages.

I only use my digital camera now as a backup due to it having a longer battery than my phone.

Your fire alarm should have battery backup though so temporary outages may not be an issue. 

For less than $50, I bought a battery operated 24 hour "logger" from an electronics supplier, put it in their unit for a day, then plugged it into my computer to print a detailed graph showing the true temperature swings.

There are meters that send a signal using cell phone towers (note that now you will need either battery or power at the meter) and others that use other wireless spectrum for reading.

.- Unplugging a toilet which requires plunging- Light bulb replacement- 9 V battery replacement- (I will update the list as we come up with more ideas)Anyway, the list clearly will get discussed with my attorney before it's implemented, but I wanted to see if anyone has a section that helps explain to tenants what WE ARE NOT DOING FOR YOU, because it feels like we are being too nice on my side and need to implement a better policy. 

And that one didn't work anymore, even after changing batteries.

@Shannon Tidwell-Porth - This goes at DST change with the subject "Reminder: Cold Season Preventative Maintenance":Folks,As [Daylight Saving Time ends this Sunday], here is a checklist that every homeowner/renter should go through: 1.Replace smoke/carbon monoxide alarm batteries.The National Fire Protection Association suggests replacing your smoke and CO alarm batteries twice a year, which is why they also suggest the task coincide with the twice-annual time change.

Especially to do it right and get Leeds Certification. 2) A lot of the building techniques, products and practices are not practical, they are just there to be cool and groovy. 3) To run a house with solar requires a huge system, plus battery back-up, once again terribly expensive with a long payback that limits it to the wealthy.Not saying that there are not positives to the whole concept, of course there are, but it is just not viable, may never be, because unfortunately, money is the driver as always.

I had my realtor check it out and he told me someone turned off the Wi-Fi on the lock and took out the batteries.
