Czysty Plan: the smart-home bill detective
A Polish-language blog tests smart-home devices against real household energy costs, using local electricity and gas prices.
Field notes
The blog frames smart-home purchases as measurable household economics: devices are tested in homes or apartments, compared before and after installation, and evaluated against Polish supplier tariffs. Its visible examples include five thermostat heads tested in a centrally heated apartment and standby measurements for more than a dozen household devices. The site states that it buys or borrows equipment and avoids affiliate links, while some article and publication-frequency claims remain statements from the site rather than independently verified results.
