    Just brought an Ecowitt compatible weather station from Germany and saw this sensor at a good price. Figured it would give more interesting data than the lightening one that I was interested in.

    Popped in some batteries and the HP2550 console found it almost instantly. It sat inside for a couple of hours reading zero particles (good air quality) so I lit a candle in the same room. Sensor works! And candles are really, really, really bad for your air quality it seems. Air quality improved slowly over the next few hours and only really peaked cooking Christmas dinner.

    Thought it might be malfunctioning, but it seems candles, roast dinners and fried breakfasts cause the most air pollution inside according to a well know search engine. It's now outside and telling me that my seaside air is good except for New Year's Eve when the Air Quality changed to moderate after the firework display about 1 mile away.

    My only grip is that you can't set an alarm on the console to alert you like you can for other sensors. Hopefully a firmware upgrade will fix this. It does however upload the data to the Ecowitt website so you can track it over a period of time which really is how it should be used.

    Esteticamente me l'aspettavo più piccola, ma non è un problema,
    in dotazione vengono fornite anche 2 batterie ricaricabili,

    Se avete il Gateway della stazione meteo già attivo e funzionante ( provata con GW1100 ) basta inserire le batterie, il collegamento è quasi fulminio, tutto in automatico
