Is it safe to update TP-Link Kasa devices' firmware

Hi all,

My home automation is heavily based on TP-Link Kasa devices, I have 22 of those in total.

Since the 2021 firmware screw-up from TP-Link were they removed HA access to the devices, I haven’t updated any of my devices’ firmware. However, I am wondering if it is safe to do so.

I have HS220 switches, V1 and V2, HS210 switches and HS103 smart plugs. Is the latest firmware version HA safe?

I’ve never updated the firmware on any of mine. Began installing them in sept/Oct '21 fwiw.

Also never had the issue you describe. Not sure when that was…

I use the same switches and plugs and are all up to date and I have had zero issues. I never understood why people hate updating, almost all devices I have ever used, updates made them better or safer. Anyways sorry about the little rant, but good luck.

No idea what devices you’ve been using, but you should consider yourself EXTREMELY fortunate.

This is the thread talking about the problem: TP-Link HS110 Smart Plug disappears after latest firmware update - #76 by MrMandrake

It was only on HS100 and HS110, which are the UK versions of the smart plug, but it got me scared, so I never updated my firmware since 2020.

TP-Link offered a half-backed solution with beta firmware, but I never figured out if they ever fully reverted the changes to the main branch of the firmware.

I see that this is your first time posting. Welcome!!!

If you are not new to the home automation game, you are a super lucky person, as most home automation manufacturers are a bunch of a******* that don’t give a s****** about their users, so they break features willy-nilly.

Sorry for my bleak comment. But that is my experience so far. I have been trying to move most of my stuff to ESPHome to avoid being lockdown to a vendor or online webserver that can disappear in the blink o an eye, like Insteon Hey Insteon users! - Home Assistant

You might be more successful in finding a solution, by starting a new thread.

I have never experienced this error. Are you able to add the switch in the Kasa App?

Yes i am able to add the switches in kasa app
What is thr fitmware and hardware version of your switches and also thr version of HA

HS220 - 1.0.8 Build 210423 Rel. 075507
HS200.V2 - 1.1.5 Build 210422 Rel. 082129
HS200.V2 - 1.0.9 Build 221011 Rel. 195547
HS103 - 1.1.4 Build 210409 Rel. 113427
HS102 - 1.0.8 Build 221011 Rel. 195515
HS210 - 1.1.5 Build 210422 Rel. 113212

They are all working fine.

HS220 has new firmware 1.0.10
Wondering if anyone has updated the firmware.
I have 36 of these switches and would hate to cripple my HA setup. Sadly I don’t honk I can just update a pilot device to make sure it’ll work- looks like it’s all or nothing…

Any news on the 1.0.10 firmware?

adding a datapoint for others:

I just updated everything I have and local access seems to still be working fine:

Just updated my HS220.V2s to 1.0.11 Build 230908. Local access seems to still be working. My test was “Does it toggle instantly from the dashboard”, and I would say “yes it does”. Does anyone know an easy way to test local polling? A curl command to ping them or something?

Unplug your internet. That way you can validate that there’s still local control, and ALSO that nothing relies on phoning home.

I know this thread is old, but I am just getting started with Kasa on my HA. I tried the Kasa integration and it is not working. I updated the firmware on all of my devices during installation. I have a variety of brand new switches and dimmers. NONE can be discovered by the HA even if I enter a known IP. I have tried both the Kasa and the Tapo versions, neither will add a single device. All had their firmware upgraded. Has anyone had success with new devices? As in October 2024.

I have several TP-Link device switches and plugs that have been running for some time. A couple of weeks ago, I added 3 KL125 bulbs for outside use with no problems.
