Hey, you all hit the tenant jackpot!
You get to report L AND collect 3 months' rent. You should all club up & sue her together. You can also just apply for a restraining order requiring her to give you back control of the thermostats. L will probably terminate the leases, in which case you'll get to sue her for retaliatory eviction.
