As discussed in another thread, it appears that modifying the driver is not going to remedy the issue of the device flooding the network with tons of messages (and probably going through batteries quickly). I am planning to resort to a polling approach. I plan to connect the white wire of the sensor to common via a switch, such as one of the relays of a Zooz ZEN16. To test the state, I need to turn the switch on for about a second then process any resulting events. I think I will be able to accomplish this in a Rule Machine rule. If not, I will have to learn to write an app.
