Thinking about purchasing a hub to control zwave devices my question is if i have a dimmer being controlled by a pushbutton switch in a room does homey know the state of the dimmer. If i turn it off from the switch and i go to the app will it show it as being off and then can i turn it on with the app. ---

Yes the app knows the state of the zwave device (and depending on the zeave device - also the power usage) as well the current it also records how and when it state was changed. (Pushed, the app, alexa, flows). ---

Just remember a good mesh network is required to ensure fast and accurate sending and receiving of data from the zwave devices to a (any) controller. ---

I think i will use wifi or zigbee devices with Homey and stay clear of z wave. ---
