Smile Asuswrt-Merlin questions and possible feature

I've been using my new AC66U with Asuswrt-Merlin and have been very happy with it's performance over my old and tired Linksys G router.

I wanted to double check that when one of the radios is disabled does that keep that radio's chip in a sleep state or low power state? I don't have any 5GHz devices so to keep the AC66U cool i disabled the 5GHz radio. The tools page doesn't show the 5GHz radio temperature so I figured it is in a sleep or low power state. My AC66U is sitting on a 15" laptop cooler that has dropped the 2.4GHz radio temperature to 43C where as without it it would run ~54C. And the ambient in the house is 20C. I'm hoping this setup keeps the router cool and helps it last longer than the dlinks and linksys routers i've used in the past.

And would it be possible for the router firmware to pickup USB HDD temperatures ie through SMART to display the drive temperature on the tools page or USB application page?

SMART isn't generally available for USB devices, except for a few that hack it in their controler.

Thanks RMerlin,

I figured I'd ask just in case. At least I know the router is running cool.

Well, I have a few external drives that I can view smart values from. Do you think it would be possible to add "smartctl" command in the future?
Thanks RMerlin.

I think it is already available through entware.

Yes, you're right!
In case anyone wants more insight about how to do it, open telnet and type:
Code:
opkg update
opkg install smartmontools
Now you have installed smartctl. To use it type:
Code:
smartctl -a /dev/sda
If it tells you something about smart not being available, try:
Code:
smartctl -d ata /dev/sda
and then "smartctl -a /dev/sda" should work.
