Ive had my Wyze cam Pan v1 since 2020. I recently had to do a complete reset and upon installing tge latest firmware, which I had to flash from an sd, I too discovered my detection zone was no longer a grid but one huge rectangle. This does not work for me at all due to motion lights being triggered by the wind etc and setting the cam off all night. Im upset but jot suprised with Wyze at all.
Yet again Wyze is screwing over their OG customers just to make more $. I say this from experience since the first time I had trouble with my cam (right after the warrenty expired) I had to go through 13 different agents before they would even acknowledge my issue and not just gell me all the same things the troubleshooting did. After foing through another 10 agents and all togther about 100 emails they just stopped replying to me.
