I could extend my house alarm system into the shed, but I first I would need to ensure that won't false trigger too and it's not my preferred option.

thinking out loud here, could it be instead of interference being the problem, rather the faraday cage style of the shed - blocking the signal to the alarm/base unit. causing the false alarms (alarms goes off when signal from the sensor is lost).

the proper solution is a wired option. wireless is great in principle, but always heavily compromised for a large number of reasons.
