First Alert Smoke Detector not connecting to network

I've read and followed all instructions i found only and now completely baffled. I unfortunately and mistakenly removed my smoke alarms (thinking there were duplicate entries) and now i can not complete setup due to this out of network error. The instructions on the app tells me to use a pinhole reset (no pin hole on the 2nd gen). I reset 50 times minimally across 3 smoke detectors. My only options it seems is to repurchase 3 new ones but now there does not seem to be an ETA to deliver the new one i want to install. Regretfully frustrated and don't know what else to do.I also went into the base station to remove any zwave devices (not all) and received an error
