Why does my empty property still use electricity?

An empty property always consumes a little electricity due to the refrigerator, router and possibly a boiler or camera. What stands out are peaks or structurally higher consumption without a clear cause, which can result from a forgotten thermostat, an inefficient appliance, or someone who is unexpectedly present. A metering module with an always-on group shows per property when and where consumption occurs, but does not detect defects: that remains the work of an installer. For a single property with few rental weeks, the benefit is less self-evident.
