Ok yeah I only have 16 devices but I have 188 entities - I haven’t had any issues with sensors except with a power mains reader that didn’t support zwave+. After I removed that everything has been great. I also have a Zigbee network of about the same size which has also been pretty solid. One tip I didn’t know about at first is that you should have your transceiver plugged in to a usb extension cord and not directly into your pi/whatever.
