Is anyone familiar with a battery operated or hardwired to 220-230V smoke, natural gas, and carbon monoxide detector? Preferably one that can be monitored remotely (I want to connect it to Home Assistant). I've found this one, but it works with 120V. There are a bunch of remotely controlled ones on AliExpress, but are not all 3 combo.

  • How about using that one, with some voltage converter?
