I did get a response to this from Wyze in a different thread. They told me they were no longer going to be made or sold. They are not coming back.
Last I checked, you could still buy some from some 3rd party resellers, especially within big starter kits (ie: includes a cam, bulbs, plugs, and Wyze sense).
Otherwise, you’re stuck with V2 sensors now. You will soon be able to order and use them without any home monitoring. In fact, on Feb 25th I just got an email telling me:
Many of you have been asking when you can purchase Wyze Sense v2 as standalone products. We’re currently only offering them as part of our Wyze Home Monitoring bundle, but we promise that they will be available for individual purchase soon.
So, you’ll be able to buy them without a subscription or the keypad. I think the new sensors are better than the old ones in every single way except 1…size. I loved the smaller size of the V1 sensors as I converted many of them into smart light switches, and it’s nice to have them so tiny, The new V2 sensors are about twice as big, which isn’t terrible, and I am happy for all the benefits that come from it (I can use rechargeable batteries, these won’t brick and go into a lockstate when the battery gets low, adjustable motion sensitivity, better reliability and range, etc). The cost isn’t that much more, and is still way less than every other company charges for sensors.
Basically, if you want sensors without dabbling with a subscription, you’ll have to wait a little longer or look up some resellers. Or, you could always order the HMS pack anyway and just cancel the service immediately.
Or you can always buy the yearly subscription like I did for basically the same cost you’d pay without it anyway…get the starter kit free, then just leave the entire thing in “practice mode” for the whole year and you will have all the monitoring disabled. Noonlight will never get any notifications and will never monitor anything, it will be just like the monitoring company doesn’t even exist, but you’ll still get otherwise total functionality and for basically the same price as not having it. I confirmed this Wyze. Practice mode can be enabled indefinitely, completely shutting out the monitoring company and allowing you to have full functionality…and then you don’t have to wait for everything to be sold separately (though they said they’ll allow this soon anyway).
Hope some of the above helps with whatever you decide…in short, V1’s are never coming back. You can use what you have and you can connect them to the new V2 hub…but they won’t be manufacturing any more.
