I am still rocking my original WM-918 from like 14 years ago and over that time accumulated some spare parts.
Recently I purchased for parts, what i thought was a complete station, from Italy only to find today when it arrived that a language miscommunication resulted in the one part I needed not being part of the delivered package, the humidity/temperature sensor. Sigh.
So a have a few spare parts for sale if anyone is looking. Send me a PM and we can start negotiating (in English ;o)
Cheers
Phil
