I cant see anywhere on the packaging, amazon or argos about them being Tuya. And i did see the Paul Hubbard video the other day with the workaround. Its not too much of a big deal because im connecting the TCP app and Smartthings to google Home anyway. So i can still create routines. Ie, Iv done it on google home so if i say “turn TV on”, it will turn the Samsung Tv on(smart things) and also the Livingroom Bulb on(TCP).
