[2] With camera powered up, press reset for 30+ secs. Then power cycle Login "administrator" no pass. URL is http://ipaddr/img/video.mjpeg. From https://itbyfire.blogspot.com/2017/03/hacking-xfinitys-home-security-cameras.html

[5] Sometimes you need to truly remove battery and reconnect / power cycle to get ziggbee2mqtt+HA to see settings made on the thermostat manually.

[6] USB + careful antenna placement via low loss cable safer than remote serial. Tasmota sometimes reboots itself and has lost serial port config. No good if away from home. Wifi 2 zigbee (virt serial port) bridges are prone to errors in the link (tasmota+sonoff zbbridge). I noticed high traffic on a wifi link can drown out the low bw wifi2zigbee. Also need separate UPS for such a bridge for power outages. USB based /dev/ttyUSBx adapter gets power from already UPS'd server.

[8] No need for wifi half of unit. use power/setup dongle to keep it wired. Hold reset behind camera down for 10 sec. Then "adminstrator". URL http://ipaddr/img/video.mjpeg See excellent descripiton by https://itbyfire.blogspot.com/2017/03/hacking-xfinitys-home-security-cameras.html
