For six months, there was electricity in the house. Sometimes it drops to 180. Smart equipment refused to work, issuing appropriate messages and low voltage. I complained to the management company - we pay for 220 and pay a lot for the Moscow region. We arrived, half a day forged the transformator-like all the norms. A few days later, the smart device turned off again and issued a high-voltage message. It appeared on the 260. They did fucking. I went for a stabilizer.
