Video, how Sense detects TV’s (not true detection)

I found this interesting. If it wasn’t for WiFi integration, I wonder how many TV’s would actually be detected. None of the six in my home have been and four have wireless capabilities but are about five years old.
The living room WiFi TV is a little newer and a 3D Tv, I figured at least this one would be detected but not yet.
This guy (Jeremy) has done four videos of his progress with sense so far. This one is at day 477 so he’s not completely new.
I’m disappointed knowing these aren’t native sense detections.

Very hard to detect / identify On/Off signatures for most electronics for numerous reasons:

  1. Standby - most don’t have a clean on/off. They come out of a low wattage standby and go back into low wattage standby.
  2. Power supply - the characteristic power utilization of the actual electronics turning on/off is hidden to by standby power and the power supply which stores energy.
  3. Content dependent power usage - the power usage of TVs, stereos, etc depends heavily on the video and audio content. So unless you play the same exact song, the waveforms will never be the close to the same. With ancient TVs with CRTs, instead of processors and LCDs/LEDs, Sense could have probably identified things like the flyback transformer, but new stuff is nigh impossible.

So using the network detection interface is really quite appropriate.

Sense found my LG OLED TV shortly after installation. The problem is the usage it reported is not accurate at all. I’ve since plugged it into a HS110 for accurate usage numbers. But doing that raises another issue/bug.

Agree with @kevin1, unless you have an old monster power sucker I don’t see how Sense could ever detect a modern TV. Maybe it’d detect an old DLP?

The only way they stand a chance is to use the network like it or not. It’s clever and many would never know the difference, better something than nothing.


I would rather sense detect but the only thing I can say I really dislike about network detection is it looks like it’s time for me to upgrade TV’s
That works out to a personal problem

Good luck, I bought a new Sony TV about 4 months ago and no dice. Maybe I should hard wire to help detection.

I’m an idiot. Here I was thinking my TV’s were WiFi. That’s not the case, they are connected to Dish Network Hoppers and Joeys and that where Internet access is coming from.
It appears that I’m just behind technologically here and if I want them detected then I’ll have to upgrade or see if Sense will detect through the Dish equipment (don’t see that happening).
I’ll probably just get an HS110 when I can afford it. I’d like to ha wine at each television location where there are several devices plugged in.

kevin1 what do you mean by (using network detection interface)

Sense uses WiFi messages (broadcasts) sent by smartTVs and other smart devices to figure out when that smart device turns on and turns off.

Don’t forget that Sense is on your 2.5Ghz WiFi and most people put TV’s and other devices like streaming devices, computers, laptops and gaming systems on their 5Ghz band for better bandwidth so that means that Sense won’t know when they turn on and off. Everything in my house that has the capability to run on 5Ghz is on 5Ghz and everything else is on 2.5Ghz like Sense and all my smart plugs.

The wifi spectrum that you’re on has no impact on what Sense detects. If you’re using different subnets within your network that will cause problems

In my Netgear wireless router, regardless of which frequency channels are used, they all talk to each other. I didn’t want to deal with the complexity of breaking my various systems down onto different subnets, so everything is still on the default.

Sense still hasn’t picked up any of my wireless networked devices, despite enabling that immediately after they offered it. All of our three TV’s are too old to have wireless, so I actually didn’t expect Sense’s wireless to help with that.

I wasn’t sure about this so I asked one of the engineers and in many cases, band does not matter. But apparently they’ve seen some routers where band can prevent the packets from getting to Sense. So band can matter, but not always.

@andysounds like you have automatic band steering. I also have the same but before the latest firmware update, steering was manually done by MAC address. They are both still on the same LAN

Learn something every day. ((-:wink: I’ve never seen that, perhaps I’ve been lucky with router choices.

Thanks for the update. Can they share which routers to be on the alert for?

I have seen some modem/router combos with separate SSIDs for 2.5 vs 5.0. I’m guessing those might cause trouble.

Being on different WIFI networks should not cause a problem, provided that they are on the same broadcast domain AND don’t block packets.
My WLC system blocked some of the packets between WLANs (and/or between the WLAN and LAN).
This caused an issue with the HS110s and HS300s. I ended up putting then all on a crappy 2.4Ghz WAP and now they work fine. I hate using 2.4Ghz because my system can see 120+ 2.4 Ghz SSIDs. It sees less than 10 5Ghz SSIDs. Sense, Nest, Ring and KASA are the only devices that I have using this band.
