This is a weird question, given the capabilities of today’s WiFi devices, etc., but… I accessed the WiFi console site for my home’s WiFI device and I noticed that the switch control devices are constantly using the WiFi at the HUGE rate of about 35 - 300 bits per second.
What the heck is going on and should I be concerned?
VERY small that.
On a related note…
Yesterday when I went outside, I noticed the neighbors dog was barking. Do you know why?
Sorry, you don’t get any more details than that.
Simple answer - if I have to guess, probably what you’re seeing is the bandwidth rate at which data can transfer between those devices and the WiFi access point. Typical for modern routers with MIMU.
Complicated answer - refer to @Sir_Goodenough post. You didn’t provide enough background and information to give you a better answer.
If this is your surveillance Camera, you should be concerned, because it’s only about 38 Bytes per second @ MAX
Bit rates is what it “assume” it’s capable of, Hardware vice, and taken the signal-strength etc etc in consideration. As it are/seems a Switch, most traffic is “negotiations” ( Keep alive, Responding to Requests/Commands )
Does this in “Other” terms mean You see this in Your Browser Console Of Your Router ?
The only time you need to concern yourself with this data is if your Wifi network is slowing down and getting congested with all the devices that you want to use AND its affecting the rest of the network.
You can bare run a ping witout exce ding those values.
What is the make & model of this device? Maybe a link? I’m curious.
Basically, what I was asking is this: Is it normal for devices to ‘constantly’ communicate with the computer? Yes, I understand that communication needs to happen, but must the communication be continuous?
Basically you can’t control that, all wifi devices “Broadcast” , All Devices are “Listening” , they also has “mDNS Caches” , in various small amounts
Basically ALL WIFI Devices are like small ANT’s …pip pip piiiip piipip pip 
In Short they are like small kids, which don’t want to stay alone in the dark,
Anyone there ?, im here !, beside whatever they are capable off, what they can “offer”, You name it !, they even store i.e addresses to services from other Devices etc , thou again for a small amount of time TTL, ( Often few minutes mDNS cached )
If Your Switch don’t have or loose it’s cache, It’s IN the dark, and have to retrieve it so it Calls out, “Where are You ?”, hopefully someone answers “Im Here !”, … ahhh so you little switch can feel “alive” Again …for a few minutes
They live a terrible stressed life, if the TX RX are “gone”, then your Switch are Gone, or deep-sleeping, and might not find the way when it comes online, if none want to talk with it
You are looking at their TX RX, be happy they are alive
Devices wake up send out a broadcast of sensor data and anything else requested by the client then go to sleep if they are coded to do so if they are also battery based devices.
Thanks - hadn’t thought about it deeply, but what you are saying makes sense.
Don’t … imagine wifi, zigbee , and phone signals etc had different colors,and you could see them 
… How many of the signals do you think your body are absorbing in your Home ?
The correct answer is ‘it depends’.
It comes down to design. Sometimes it is necessary, often it is not. It becomes embarrassing when you examine code and realise that somebody has implemented a vast continuous polling loop when reactive interrupts would have been far more efficient.
This often indicates a little more time should have been spent on the design phase, looking at requirements and consequences of design issues. Many a large project, getting bogged down with poor response times as it grows and eventually overloads, has been able to be slicked up with a simple redesign of how tasks are managed. Systems analysis should be done up front, not as an afterthought when things go pear shaped.
