Silent at Office but Continue Checking

[steelersmb]

I have been using Llama then Tasker but wanted to try Automagic out. I need a profile that when I am at the office between the hours of 8:30 AM and 5:30 PM, switch the phone on silent. However, I also want it to switch to normal when I leave for lunch but when I come back, switch it back to silent. Here is what I did but I wanted to make sure this is the best way to accomplish this:

Periodic Location update every 5 minutes > check to see if I am connected to the cell towers in the area > check the time range > true, change to vibrate, false, change to normal.

Does the Periodic Location Update running every 5 minutes use up a lot of battery?

Thanks for any feedback.

The more often you set it to trigger, more it will eat the battery. In your situation it might be the best option. However, you can add a second flow to disable the first one, when it is outside of desired time range. That will definitely help with the battery.
