Controlling a relay with two way (thinger.io and hardware switch

i would like to control a relay from your site(thinger.io) and also manualy from a hardware switch, the problem is than the toggle switch on your site should be updated according to the relay status ,for example i i turned on the relay from your site and then turned off manualy from a hardware switch the switch on thinger should be showing “off” and vise versa
it should work like a regular two way switch

thanks
