Since Sense is not in Homekit you cannot use the motion or door sensors to trigger actions just yet which is why for the cameras I opted with GPS location based off my families phones. Also not sure about a guide but figure in this post I would try and best explain the process, I was just messing with different smart devices in my house and figured it out. Webhooks are really easy. If you open the Webhooks service on the IFTTT site there is a button for documentation where they give you the URL you will need to use to launch your applets from Homekit. Start in IFTTT and create a new applet starting with webhooks followed by your Wyze action (Example: Webhook Name: “Camera_Off” followed by Wyze action to turn off the camera.)
Then go to HomeKit > Automation followed by a new automation. Select when “Anyone Arrives” and go to the next screen.
On the next screen go all the way to the bottom and click “Convert to shortcut”.
On the last screen delete the pre-populated action and add a “URL” action followed by “Get contents of URL”. To call multiple IFTTT Webhook applets you can repeat this step for each applet you want to run on this single trigger. When we get home it turns off one of my cameras and disables the motion notification so it doesnt re-enable the camera when we are walking around.
If you have a smart button or switch you can convert their actions within Homekit as well to “Shortcuts” and then follow the same process of adding the URL followed by getting the contents of the URL. This will help your guests or family who would rather have a physical switch instead of yelling at Google/Alexa or carrying their phone with them.
