If you have Home Assistant (or similar) for your automation and you are starting, I'd recommend Zigbee or Z-wave devices. A few wifi bulbs like the ones from this deal are OK, but you could get in trouble (signal drop) as you keep adding wifi devices to your network.
If you live in a small apartment and don't plan on adding too many bulbs, then these will work.
Zigbee and Z-wave create their own mesh network which makes it more reliable and they use a different protocol so all you wifi devices will be OK.
For Zigbee devices I think Philips Hue are the best/more reliable but of course way too expensive. Ikea TRÅDFRI are recommended and not too expensive. Seng led are cheap but I do not recommend them since they won't act as router/repeater for the Zigbee network, compared to TRÅDFRI or Hue (unless this was changed recently).
The downside of Zigbee or Z-wave is that you also need a hub/gateway to control your devices but since you are asking about automation, I think at some point you will have to deal with some sort or hub (RF, Z-Wave, Zigbee). I think some Amazon Echo devices can act as a Zigbee hub but I'd recommend using something like a Zigbee USB stick and running zigbee2mqtt and then you can do all your automations in Home Assistant and/or Node-RED.
Good luck!
These are great bulbs. I've been using a couple of these for several years in my Alexa based smart home. Just be aware that these bulbs are 800 lumens (equivalent to 60 watt incandescent bulbs). Kasa makes brighter bulbs of 1100 lumens, but they are more expensive. Kasa (TP-Link) makes very good products.

Currently I'm using Kasa, LIFX, and hue bulbs. With Kasa I have these standard ones and canned lights. Out of the 3 Kasa is ranked lowest for me. Here's why, they get reset more then my other bulbs- kids or grandparents accidentally turn on and off the light in repetition reset the device requiring them to be setup again. Out of all 3 they were the first to go defective 1 of the canned lights can no longer hit all color ranges and is limited in brightness. Also other canned and regular lights have been known to flicker and change color also go on and off . LIFX is the ranked 2nd because I feel they have better coloring and stay connected without having to re setup. They also have many more features such and strobe, animations, themes, and music sensing. I also feel the app reacts fast and there is no delay between switching them off in the app. Also the new ones have additional features such as infrared to help with cameras at night and clean mode that kills germs apparently. Hue is top because they never disconnect and have very similar features to LIFX. Having the hub creates a great advantage with connectivity, just hope they increase it from 50 bulbs to more. All 3 connect very easy to Google home or ihome.

Quote from MuddyBottoms :
Please keep this in mind. Smart bulbs SUCK if you live with others less technology minded as you. If the switch is shut off the bulb drops from the network. The general rule of thumb is bulbs in lamps or in fixtures where switches don't exist or really aren't touch. For places that have switches, replace the switch with a smart one.
True story. If you have multiple bulbs connected to a switch, just install a smart switch to control all of them. The downside is that you can't change bulb colors since you have regular bulbs installed.

If you install smart bulbs instead is, if you turn off the switch, they don't work because no power going to them. So you'll have to cover up the switch for non techy people in your household.

Also, this is the cheaper of the Kasa bulbs at only 800 lumens so it wont' be so bright.

Kinda specific question here: if I have a Kasa switch connected to my front porch light (currently programmed for sunset to sunrise), can I replace the bulbs in the porch light with these and program them to go to a certain color when the switch turns them on? .. or do they retain programmed setting once turned off/on?
Thanks in advance for any insight!

I can't post a screenshot but just replying to let you know: I was able to go into my Kasa smart bulbs and set a scheduled on time (or sunset) and select a Scene where you can have your bulb color presets. So yes you can.

They can't do local control so if you flick on the light switch 1x or 2x they turn on without having to use the app?

I bought these a year ago and they buzz/hum and take a few seconds to turn on (not an exaggeration). Pretty disappointed in these particular Kasa bulbs. I have a different Kasa bulb model and a few other brands that are silent and respond quickly. Please check the reviews before buying.

Philips glass par20 90cri warm glow leds still more pleasant looking to my eyes, more natural warm.

dimmed color is an interesting novelty, but I never use it because I swear I can detect a flicker, doesn't feel right.

These are mostly good for automated timing.

Quote from pechango :
100 devices per point
https://store.google.com/us/produ...s?hl=en-US

My AP can handle up to 200 devices and I have around 60 connected to it right now.
Just so you're aware, you're falling for marketing wank.

The 200 devices number comes from the default DHCP range (192.168.86.20-250=230 IPs available with some room for devices coming in/out).

The 100 per point is because they're assuming any given devices is never taking more than 1Mbit/s (1.2Gbit/s max speed, they're reserving 200Mbit/s for overhead in their marketing, 1Gbit/s / 100 devices = 1Mbit/s per device). If one device is streaming video at 50Mbit/s you've "lost" 49 possible devices on that point until it is done streaming.

Quote from Illnasty :
I only owned one of these bulbs and 16 of the Sengald (or how ever you spell) zigbee garbage bulbs. The Kasa is way better and doesn't need the stupid SmartThings hub. Kasa makes the best switches and maybe bulbs in the smart home atmosphere but DO NOT USE their cameras. They do not provide MFA and anyone could log into your account and watch your cameras.
Kasa used to be good, then they decided to drop local control:

"Thank you for your continuous support of the Kasa brand." lol
Downside to IoT devices... manufacturer stops supporting them, you're screwed and end up with a paperweight. Or worse, they want to start charging a subscription.

I think you have no clue how networking hardware works. There is zero chance they are limiting each device to a specific speed based on a max theoretical throughput. Not even the crappy target routers do this. Also, just because a client is connected doesn't mean it is transmitting or receiving all the time, just ensuring the connection is open.

I also see you can update the IP range in settings too (I've never used google wifi by the way) to whatever range you'd like as long as it is a class c network. Just because the default is 20-254 doesn't mean you can't change that to be 6-254 or whatever your needs are. That "overhead" you speak of is so you can have hardwired DHCP assignments that don't affect connected/disconnected devices.

The number of clients allowed by a device is dictated by the radios/hardware and then software. This isn't "marketing" hype and it's not unheard of to hear of devices allowing 100 clients to connect to them. My old Linksys for 15 years ago allowed up to 50 and that was questionable. My current AP can support up to 200 alone.

That is true is you live in the UK and use the 220v version of these devices (you have to read a bit deeper in the alert you referenced to see that). The local control API of US-based devices has never been affected by this issue. When using Kasa products with Home Assistant, it uses that API for local control and has always worked great.

I'm sorry to hear you lost faith in the Kasa product line because of that misunderstanding, but no sense steering others away based on incorrect information.

I never said they were limiting devices to a specific speed. I was providing the disclaimers that their marketing materials quite literally make: Go to https://store.google.com/us/produ...i?hl=en-US scroll to the bottom of the page. What do we find?

Quote :
This is based on only using connected devices at a maximum data rate of 1Mbps
I provided the math on how they arrived at 1Mbit/s per device as well.

The overhead I am speaking of is not for "hardwired assignments", they use DHCP just the same as WiFi clients. It's because when you are using DHCP to run a network there will be devices who have gotten a DHCP lease but are not currently powered on. e.g. If you have a desktop PC, turn it on, let it get a DHCP lease, and then turn it off you have "used" 1 of your DHCP assignments until that lease expires. If you have a guest over their phone will get a lease. When they leave, that lease still exists until it expires.

BUT... actually digging into this more. When they say "200 devices" they are actually talking about 100 devices per device, but the pack comes with two devices!

Quote :
Router and point can each handle up to 100 connected devices
So it isn't even the DHCP range, it's literally just each device can support up to 100 devices if connected devices limit themselves to a maximum of 1Mbit/s of traffic. So don't get mad at me. Get mad at Google if you disagree. That's what they are telling their customers when you drill in to the materials. ( https://store.google.com/us/produ...s?hl=en-US ) (Along with our handy disclaimer at the bottom: This is based on only using connected devices at a data rate of 1 Mbps each. )

Are these big problems? No. I never said they were.

But when Google says "Up to 200 devices!" what they are doing is giving a marketing spin to things to try and spin something to make people think one thing when it means another. A couple of kids streaming, playing games, etc can really knock into that 100 devices number.

What you are doing right now is akin throwing a fit when someone explains that a 1GBit/s cable internet connection will not actually be 1Gbit because of node congestion and line quality.
