Dear OTK renters
We have just had quite strong strong earthquake. Please check "water heater controller" and "heating boiler controller" if your house has those.
They may be giving some kind of error code and stop working due to the earthquake. It usually starts working again after you reset/reboot the system by hitting power button twice.
