Support for P100 Smart Plug #83

I am interested integrating my TP Link Tapo P100 plugs into homeassistant. Currently homeassistant/core uses pyHS100, but hopefully can be updated to use this module instead / as well.

Has any effort been made to integrate the P100?

In homeassistant the discovery fails, so my starting point will be to try manually discovering the devices with this module and see what happens and if the errors are useful. I am hoping it is just the discovery that needs updating, maybe.

We're all excitedly awaiting this PR to be finalized and merged in to use this module as the homeassistant integration.

I have tried an nmap scan on my P100 and it shows all closed except for 80. I have managed to capture some pcap files of traffic to and from the static IP, but I can't make sense of it. Presumably it is encrypted in a similar way as described here https://github.com/softScheck/tplink-smartplug. I tried loading to dissector, but it doesn't seem to do anything. I don't know if I should be seeing something about TP-link protocol, or if that is only after the dissector is working.

I have understood from somewhere that this series of devices is using a different app than the kasa app on mobile, and that it is also likely using a different communication protocol.

A few questions:

  • I'm assuming the library in its current state is not working for you? Does any of the commands work?
  • Can the bulb be controlled with the app even when they are not connected to the cloud? I.e., is there a local communication protocol?
  • If the above is true, is it's probably worth investigating how it communicates. Maybe it's using the same protocol but a different port? Or maybe it's something completely different, in which case it's hard to say without further investigation what's the best way to proceed adding support for them (and/or if that should be a project of its own instead of adding support for a new protocol to this project).

We discussed about this on discord, the conclusion was that it's using a different protocol and is thus out of the scope of this project. If the state changes, feel free to re-open this.

Agreed. Thanks for your help anyway!

Looks like other product families are also starting to use a new, 80/tcp using protocol to plug a security issue, so I think it's worth to reopen this issue just in case the new protocol is the same as used by the P/tapo series.

@GDYendell could you check out if this PR allows communication with your devices: #117 ?

@rytilahti I would be happy to try it out. How do I run that branch of the integration on my home assistant instance?

To anyone who is interested about the Tapo P100's protocol, you can find a working solution here:

There is a working HA integration as well:
