Power Failure, Temperature, Water, Continuity Sensors with Text Message and Email Alerts, P3 Multi-Sensor

Is there any way to use this with an ethernet connection instead of wifi? is there another probe available that can measure temp' below -55 c?

How does it monitor power outage? Does it have batteries to send alerts when it loses power?

Can the temperature range be set to alert outside a +60F to +95F range?

can you get longer waterproof temp sensors?
