Most of the smart switches I've seen are designed to accept commands, where they are the action of a rule triggered by some sensor. What I would like are some smart switches which are capable of sending an event to my Hubitat when the switch is toggled. I have successfully used TP-Link WiFi switches with an app on the Hubitat, but it is less than ideal. It works by polling the switches for their state at an interval, however there is a very noticeable delay due to the polling interval.
A more reasonable design would be a smart switch that can be configured to inform an arbitrary web server, and an app on the Hubitat which can accept that message just like it must from other event-providing sensors etc. This would let the Hubitat react immediately, and avoid the overhead and delay of the polling model.
Can anyone suggest such a device?
I would prefer one that can be wired into a wall and look like a "normal" switch.
