With tnb app, there's no reason for LL to get surprises if he checks diligently.

got this also no use.. bypass those incoming electric cable ler
the only solution is, must put visit/spot check clause in the rental agreement
1. handover the keys
2. spot check after renovation
3. 1 month after moving in
4. then, periodic checking after that, like when collect rent time.
doing all this also might not foolproof but at least, those would be crypto miners tenant will skip choosing rent it.
The best solution is TNB must have centre meter for each row of shop, any meter reading different up to certain %, trigger spot check or at least trigger those shop owners TNB accounts a notice of awareness
