What it adds over a basic instrument

The core measurement — indoor temperature and relative humidity — is the same job the TFA Dostmann instrument reviewed alongside this one does. What SwitchBot adds is Bluetooth connectivity: the app logs a history graph over time, and calculates dew point and VPD (vapour-pressure deficit) figures from the raw readings, rather than showing only the current number.

For households already in the SwitchBot ecosystem

This is the same brand behind the SwitchBot Meter Pro CO2 monitor reviewed in this network’s air-quality-monitors family. Anyone who already has that device and its app installed gets this instrument’s readings in the same place, rather than juggling two separate apps.

Where we actually confirmed it for sale

We confirmed a live offer on Amazon.de. We also found a matching listing, with the same EAN, on Amazon.fr — but we did not confirm an active offer behind that listing at the time of checking, so we’re not reporting a French price for it.

  • Westinghouse 78095 infrared remote control for ceiling fans with light, white

    Westinghouse 78095

    Westinghouse's 78095 is an infrared replacement remote built for the company's own ceiling fans with a light kit, stated by Westinghouse to fit most of its ceiling fans, with exceptions listed in each fan's own specifications. It controls three fan speeds plus off, and separately turns the light on and off with a dimmer, and comes with a wall-mount bracket and screws.

    • Confirmed with a live price on five of the six markets we checked (DE, FR, IT, ES, GB) — and the strongest German sales rank of the three remotes in this hub
    • Made and branded by the fan manufacturer itself, with a stated fit against Westinghouse's own ceiling fan range rather than a code list to search or enter
    • Brand-locked to Westinghouse — none of the ceiling fans reviewed on this site (Briloner 3963016, MiKoMiKa F8808, EXTRASTAR IT-OMFSD-2003, ROTTOGOON CF1501) are made by Westinghouse, so this remote is not a fit for any of them

    Best for: A Westinghouse ceiling fan with a lost or damaged remote — Westinghouse states most of its models are covered, with exceptions listed per fan. It is not a fit for the Briloner, MiKoMiKa, EXTRASTAR or ROTTOGOON fans reviewed on this site.

    • Purpose-built for the TP11/TP12 generation, not a generic universal-fit listing
    • Confirmed with a live offer and the identical EAN across Germany, France and Italy
    • Third-party, not a Dyson-branded part — no manufacturer warranty coverage on the filter itself

    Best for: Owners of the Dyson Purifier Cool PC1 (TP11) who need a replacement filter set and are comfortable with a third-party part, since Dyson itself doesn't list a separately branded replacement for this generation on the markets we checked.
