will it notice if the temperature drops significantly so you can find out? will it notice if the power goes out?

Nope, no temperature alarm and no power monitoring. It's best to use a UPS for the base if you can.

Yes, it does. And, I think it also signals when it shuts off some time later.

If it is plugged in to AC. Mine is not using battery backup and if the power goes off, the unit goes off.

if it was a power outage yes.... one of my units is in a mountain area that frequently losses power. I get an alert that the wifi is out and the later it tells me that it has reconnected.

It must. I have had my power go out several times, and had no ill effects. These were short time periods.

Yep. It indicates that the unit is powered up. When the temp drops, the heat and fan start up.

Directly, no; indirectly yes. You'll need to contact the mfg tech support. They mentioned something about an alert service for a fee. The RadStat app allows control such as off/on, temp setting, home/away--normal thermostat actions. I think for the alarm (such as to note whether your heat has failed in the winter) you need to have the stat monitored, and I think some alarm companies do that too. There is chatter on their website forums about alarm.com.

No. The only light on it is a light to warn you when battery power is getting low.

As long as there is electricity running to it, it will register volt readings. It does not make any sounds if voltage drops below.

Depends on how close it is to the heat source and what the air temperature is at that location. Try it and check the wires closely for a few days, especially after some serious driving.

You were thinking maybe the light is psychic and would know when the power has gone off without a wired connection?

Yes, if you hit the sensor button on the remote, the AC will use that sensor's temp to determine when to cut on and off.

It will decrease the temperature in the attic. So if your attic is not well insulated you might see a slight difference in your heating bill.

This only detects a failure in the electricity supply to the device it is protecting, not a failure of the device itself, so no it will not detect a heat lamp bulb failure. If the electricity goes out or the fuse or circuit breaker blows the alarm will sound.

It doesn't If the temp is below 35 you have to bring in the house and warm it up. Once it starts you can return to the outside. All it does is hum and then trips the breaker. Not recommended

No. Please make sure you have appropriate power pluged in. Heat is usually a sign of over amped supply

The thermostat retains the last settings if that is your question. If power is out, your HVAC is out of commission anyway :-)
