I use the Tapo environment(I like it), have 20 smart device from Tapo, but have to use 2x Wolley switch and 3x Shelly device as well, because Tapo does not have 3 essential devices. Ttwo from them is a real pain for me:

1) dry contact input switch. Actually the Tapo 200B button with 2 external contact, what if I close would react like the button would have been pushed physically. This would help to link already wired buttons to Tapo's wifi ecosystem... (similar to Shelly PLUS i4)

2) a Multifunctional relay with dry contacts (like Shelly 1 Mini Gen3) It would help to open a gate or any other unit..

If any similar "Matter" device could be enabled to add to Tapo App, it would help as well, but Tapo product is more preferred as it have more features than a third party device shares via "Matter"..

+   3) A dry contact relay without neutral... (to switch lightnings where neutrals were not wired, like Woolley SA-018 Smart Switch - WiFi)

If you have information about such Tapo product or information about similar Tapo pruducts planned for the future, share with me PLS..

Thanks
