Yep we had one of these. really p****d the neighbours off. We also had a fence, with lockable gate, and extra padlock. Went down unanounced and found alarm disconnected,battery too, gate open, padlock hanging on fence. Simplest solution. Lock it up, finish renting weekly as a gite with pool, rent house long term and use the grenier when we want to visit (with pool). Pure piece of mind - priceless. Having said that, I used to be able to re - set beams annually pre-season, but I had waterproofed and insect proofed all entry points on initial installation.
