Radiator support (KE100) #422
Description
Hello,
Any plans to support the Kasa TRVs? https://www.tp-link.com/uk/home-networking/smart-thermostat/ke100/
I'd love to buy them ASAP but I need to know if they'll work with home assistant first

Hi,
I haven't heard about these and they are not currently supported by this lib nor by homeassistant.
Controlling these requires a separate hub (KH100), but as these are kasa-branded, adding support should be doable as soon as someone provides a traffic capture between the app and the hub, or goes and reverses the protocol.
iambenmitchell commented on Feb 6, 2023
I have 7 arriving today, could you point me in the right direction on how to do what you're saying and I'll do it.
I haven't done packet capture for devices before, but I have done it on browsers so I'm pretty rusty
rytilahti commented on Feb 6, 2023
As a first step you want to verify that the hub is actually using the kasa protocol. To do that, use kasa discover command to see if it can detect the device:
Alternatively, you can directly try to request the sysinfo from it:
If you get responses for those commands, that's good news and the device is using the protocol implemented by this library.
Next step is to find out the commands to control the hub itself. The simplest way to do that is to install the kasa app in an android emulator (I have heard that bluestacks works on mac and windows), and use wireshark or tcpdump to capture traffic while playing with the available functionality in the app.
You can use the devtools/parse_pcap.py script in this repository to parse the contents of a pcap file, see #388 (reply in thread)
It will show you the sent commands and the device responses.
Let me know if you get stuck somewhere in the progress and we'll try to find a solution :-)

Looks like it's not using the same communication protocol. Is the mobile app you are using called kasa or something else?
Did you already try to do a traffic capture? Few devices use a different protocol for comms which is not currently implemented: #115 #267
iambenmitchell commented on Feb 6, 2023
Yep it just uses Kasa. I've tried to packet capture using Charles proxy on iOS but they seem to use certificate pinning and thus i am unable to capture anything useful
iambenmitchell commented on Feb 6, 2023
Found these issues from other projects that reference the same product I'm using, might be worth watching them

Ouch, also for local communications? Or does it only communicate over some cloud endpoint, i.e., there's no direct communication between the app and the device?
AntonyKing7D commented on Feb 7, 2023
Hi, I'm interested in this too. I tried to capture traffic between my android phone and the smart hub that came with the radiator thermostats. It's not SSL, but it's definitely not plain text! Here is me turning off a radiator for example. 192.168.21.17 is the hub, .89 is the phone:

iambenmitchell commented on Feb 7, 2023
Oh thank god someone else has this product. I was starting to think I and 3 others were the only one who bought TP-Link TRVs because there's zero YouTube videos or meaningful google results / articles on the device. Unlike other TP-Link devices like routers and stuff.
Thank you for chipping in to the conversation, hopefully we can find some integration because TP-Link haven't updated their IFTT interfaces and Google home is useless for automation.
My google nest controls my boiler, I might replace it with a relay instead if that would work better, but even so, the IFTT api doesn't support the thermostats yet.
So I basically want to find a way to have my Nest turn off if all radiators are turned off OR aren't requesting heat (they're at the desired temperature)... otherwise, set the nest to the maximum 32° as we installed the nest in the lounge about 2 years ago which went well.. but during the last summer we installed a wood burning stove in the lounge and so when we're using that, we need the nest to be set to the maximum temp (or above 25°) otherwise it won't ever turn the boiler on and the lounge gets toasty while the rest of the house freezes
Currently I have it set up to turn onto 32° at 05:45 and set to 9° (off) at 22:00. Then in the Kasa app I have the specific schedule setup.
This seems pretty wasteful to me as the nest is running even once all the radiators have reached the desired temperature and turned off. (The bathroom radiators aren't controlled by the valves though so they take all the heat)
I wrote some logic code if that's easier to understand my objective:
if all_radiators.state == off || all_radiators.roomtemp == desired_temp {
set_nest.temp(0)
}
else {
set_nest.temp(30) }
rytilahti commented on Feb 7, 2023
@AntonyKing7D those paths (and the TPLINK_SESSIONID) look similar to the protocol implemented in #267 that was never finished. Maybe you could give it a try to see if that's really the case?
To check the discovery, I suppose something like this should work:
and even when there's no device support, maybe you can try to request the sysinfo data:
AntonyKing7D commented on Feb 7, 2023
I don't see --user or --password as parameters for kasa? Without those parameters I get a connection refused error:
sudo /home/ant/.local/bin/kasa -d --host 192.168.21.17 --type plug sysinfo
ConnectionRefusedError: [Errno 111] Connect call failed ('192.168.21.17', 9999)
tried with and without sudo .
[edit] I've just discovered the fork which implements this , https://github.com/TokonatsuFestival/python-kasa/tree/new-enc-protocol . That's going to take me a while to figure out, I suspect .

Is there any way I can help out with this? I see that code has now been added for unsupported devices in https://github.com/python-kasa/python-kasa/pull/488 , which I assume is the first step towards this working.
I have the KH100(UK) and a few KE100.
Though I can see that there's no comms over 9999 for the hub. The pcap I captured was all comms with AWS over https. Which the parse_pcap.py script, understandably, didn't know what to do with. The only open TCP port is 80 on the hub.
I've half an idea what I'm doing with python and tcpdump and willing to lend a hand.
iambenmitchell commented on Oct 18, 2023
Still no progress with this?
It’s winter again now in the UK and there’s still no solution for turning on an off the boiler based on if the KE100 thermostats are trying to heat or not. I just have to have it on all day
rytilahti commented on Oct 18, 2023
The status is the same as written in #422 (comment) – This will require someone with a device (or enough time to try to obtain the information otherwise) to reverse engineer the necessary bits and create an implementation. So PRs are still welcome and I can help with code reviews to get it merged. If the AES one is similar to KLAP, #509 might be a helpful starting point to start implementing it. If it's a completely different, that PR still introduces an abstract interface to be implemented.
@laxdog the discovery part helps only to discover devices using the new discovery protocol (which is being used by some kasa devices as well as by tapo line), so it doesn't really help that much wrt. the issue at hand. Anyway, was there any direct communications that did not go via the cloud?
DaveGut commented on Oct 18, 2023
My Hubitat experience with the protocol for the Kasa Matter devices is that is is the EXACT API and Protocol (AES) as the TAPO devices. I think this extends to the Hub. So, look toward the TAPO hub integrations as a starting point with only a few mods to get the Hub working (look for KASA.SMARTHUB vice TAPO.SMARTHUB on the port 20002 discovery message).
rytilahti commented on Oct 18, 2023
Okay, great! Then it might be useful to take a look at https://github.com/petretiandrea/plugp100 which implements support for tapo hubs to my understanding.
DaveGut commented on Oct 18, 2023
Yes. Even has the KLAP protocol (which is not used yet on the Kasa devices but i a good risk mitigation).
laxdog commented on Nov 13, 2023
Yes, I captured a pcap. There's quite a lot of chatter between my phone and the Smart Hub. I'll have a look at that other repo and see if I can work anything out.
rytilahti commented on Nov 13, 2023
petretiandrea/plugp100#153 this might be interesting for you.
laxdog commented on Nov 13, 2023
Just got the main line working from plugp100 and recognising the hub and the TRVs, I just can't control them. I'll give that PR a go soon, then maybe look at doing something in here.
DaveGut commented on Nov 14, 2023
Try sending the following command to the Hub: [method: "get_child_device_list"] and get me the data (private message). That will have clues as to the basic device commands.
You could also try the following command:
[
device_id: DEVICEID FROM ABOVE,
method: "get_child_device_component_list"
]

Just letting you all know that I have been able to control these via IFTTT per-say but limited use.
use case example:
Create a Kasa "scenes" that includes the Thermostat functions you want on the Kasa App.
Then you can trigger these "scenes" via IFTTT.
While you may not be able to see the Thermostats directly or modify them through IFTTT you can manually assign these thermostats to "scenes" which can be triggered via IFTTT
