7LM, meant in the nicest possible way, your paranoid. That reminds me I must close off access from Spain in PfSense
I usually turn off everything that I can, including water when away, water being the most important as it can easily go unnoticed. The network equipment, alarm, monitoring equipment and TV server recording TV programs is left on, as is usually one fridge freezer.
I presume you often go out, we all go out as we work and the daughters are at school/uni so like an awful lot of properties they are empty for long periods of the day 5 days of the week.
When is a fire more likely to start, the 3 or 4 weeks your on holiday, or the 8 hours 5 days of 48 weeks of the year you're just going around normal life?
PS. I have a smoke detector linked to the house alarm, and my wife thinks I'm paranoid, but she never complains about me turning off the water after one of her mates came back to a flooded house after a holiday.
