I want to know when a temperature rises or falls outside the limits

Monitoring of the temperature in a fridge, freezer, cryostat or aquarium is a simple task for iSocket 3G or iSocket Environment Pro. Do you have a boiler or heater in your remote cabin (without Wi-Fi) and do you require a remote smart thermostat? Not a problem for iSocket 3G or iSocket Environment Pro - that is cellular and therefore operates independently of Wi-Fi - to send you reliable alerts of temperature falling or rising outside the limits.
