With gmail if you have an account like example@gmail.com you can then sign up for a website such as netflix with email example+netflix@gmail.com and gmail will forward it to example@gmail.com, but you’ll still see the full address on the To line so you’ll know where the mail came from. Anything after the + can be whatever you want. This lets you sign up with a different email address for every site you visit without having to create new addresses with gmail. You can also make a filter to hide spam if one of the addresses is compromised.
Please tell me more about this interference bug.
Also wanted to add that I use the Nortek Zigbee / Z-wave combo stick and it’s worked great https://www.amazon.com/QuickStick-Combo-HUSBZB-1-Nortek-Cert/dp/B0157GOEA8
It’ll be 4k if you install the windows app for the service or watch in Edge.
