@StephanS 

There are several (now hidden) threads about this issue. To find them, you have to select "within a week", not "all time".

So far NO response from TP-LINK/Kasa/Tapo! They are active here, answering mundane issues but ignoring critical issues like disappearing devices.

What is going on???

Is this still a topic no one is allowed to talk about?

  @StephanS I have exactly same issue, on my dads valves! Since an update to the app. I have tried the recent firmware update and today a tapo app update. Still nothing but the Hubs! Cannot even see them in add new device as an option!

If i login with the kasa app i can see the valves but not the hubs! annoying as all the plugs are tapo. I put all my dads stuff on tapo and mine are on kasa so i don't have to sign in and out of the app if i want to control his devices.

I don't want to repair 25 radiator vales and the explain to my dad , its kasa for heating and tapo for lights and camera.

Please sort TPlink!

I contacted TP link through the chat and they sent me a trial version of the Tapo app, and now everything works again. So clearly it's an issue with recent app updates

  @Johnpigg 

Version?

They sent me Tapo_Trial 3.3.513 and still no thermostats.

  @StephanS & others,

It is 28-10-2024 now, is this topic / issue still active @ you place(s)?? Today i'm struggeling with the same .... :-( No Thermostate is visible in the TAPO app (i got the latest update..)

The interaction between the TAPO/KASA apps and the interaction between the Thermostates with the TAPO temperature sensors was the main reason to buy 15 pieces!! Now it's useless !!! 

@TP-Link: fix this s... problem please!

  @fwg 

I have the same problem. Having just installed the Tapo app  it can find my Kasa HE 100 hub but not my KE 100 Smart thermostat. The Kasa app is working fine with the zhub and thermostat.
