Cannot pair TP-Link HS100 plug

Mozilla IoT
#1

I have been trying unsuccessfully to add a TP-Link HS100 plug to the gateway. I am using the standard Raspberry Pi 0.10 download on a Pi3. I have added the TP-Link add-on. The HS100 is plugged in and the wifi light is blinking green and amber.

The HS100 has never been linked to a Kasa account. My understanding from the thread below was that this is not necessary fror TP-Link devices [1].

When I scan for devices, the HS100 is not found. However, it does appear that it is found, as in the run-app.log I see the following:

I’ve tried a hard reset of the plug, with the same result.

Just started with the Gateway, so sorry if this is a newb error.

You’ll still need to use the Kasa app to set up the plug initially and get it on your Wi-Fi network. I believe you can do so without attaching it to an account, though.

That log doesn’t show any devices being found, so my guess is that it’s not on your network (confirmed by the flashing lights).

HI, thanks for the reply. I should have realised that I guess.

I have set the plug up with the Kasa app, and can control the plug with the app. I can see the plug attached to my router.

However, I still cannot get the gateway to see the plug. The log shows the same entries as in the original post.

The Kasa app says the firmware is up-to-date. I have scanned numerous times, with a number of restarts of both the gateway and the plug.

It’s possible that mDNS doesn’t work on your network, which would prevent device discovery from working. You can try adding the plug manually:

  1. Navigate to Settings -> Add-ons in the UI
  2. Click Configure on the TP-Link entry.
  3. Add the IP address of your plug, then click Save.
  4. Your plug should now (after a few seconds) be available when you try to add new things.

Adding the IP address manually didn’t work either; the log showed “no route to host”. That and your comment about mDNS helped: I moved the plug so that it was connecting to a different wifi access point and it was immediately found. So I have a network problem to sort out but the gateway problem is solved.

Thanks for your help with this.
