This is a tool capable of pushing arbitrary update images to wyze devices. It works by simulating itself as Wyze app.
To use this tool, you will need to specify at least the target device's MAC address, and the firmware file. While running, it will create a http(s) server to serve the firmware binary. By specifying "--ssl" will make a https server with a pre-generated self-signed certificate. This is necessary for the wyze plugs since it only connects with https protocol. You can specify alternative port to listen at. If not specified, default ones will be used, which means 80 for http, and 443 for https. Again, wyze plugs will only connect to https server on port 443. When using default ports, you may need to run the script with root privilege otherwise it will fail to start the service.
For the first time you will need to enter your wyze.com username and password, and also do 2FA with primary phone. The login token will be cached in a file named '.tokens' so you don't need to do this entire authentication again. Make sure not to share this file with anyone you don't trust.
