Compatible with. my ancient Overhead Received promptly. Easy istallation of the device. Some difficulty attaching the sensor to the garage door because the edge of my door is curved requiring some spacer to prop the sensor mounting bracket. App function well, Siri integration is a bonus. Will be tasing the geofencing feature shortly. Can't ask for more.
Update 5/17/2022: We moved to a new state and location to a home that had the most recent LiftMaster garage door opener with bells and whistles, unfortunately its myQ technology doesn't connect to the internet. After nearly 2 weeks of trouble shooting with my ISP and LiftMaster/myQ tech support the issue is still unresolved and it appears the LOGIC BOARD on the opener is defective. Not only mine, but the entire batch. ENTER NEXX NXG-100B. Contacted NEXX customer support, they send an adapter, but when that was found to be incompatible they asked me to send a remote that can be patched with 2 wires and connected to the opener. In less than 4 days I got the remote back and installed it and IT WORKS. I can't say enough about NEXX and their TECH SUPPORT. I had some trouble connecting the NXG100, so I exchanged emails with tech support and in about 30 minutes I was up and running. This is simply unheard of. I have this device for a number of years and it continues to amaze me. More significantlu the service by NEXX us unmatched.
