By the way, this model is compatible with the ZWAVE PLUS module per Yale support. The ZW+ module has the dark green case. I tried it with the translucent green (older) zwave module and it does NOT work. They suggested I buy the module from them:
However, if you open a ticket with yale, they’ll send you a one-time code for 20% off saving about $4. You can also buy it other places… I found one on ebay for about $10 cheaper than from Yale direct.
Just search for AYR202-ZWV-USA and make sure it has the solid green case, not the translucent green case. You simply remove the red module and replace it with the green ZW module.
I have 5 of these (older) version and have been reasonably happy with them.
