  • Follow up

    This is a follow up of my Oct 9, 2015 comments where my only concern was the longevity of the batteries. Well, it has been pretty good since I just changed them almost 3 years after I set it up. And it was only the outdoors sensor that the batteries were dead. So, all in all, pretty good buy. I am now in Longueuil and moved the weather station with me.

  • Works fairly well

    Was a little fiddly to get set up and to get it to hold the readings from the three separate remote sensors. Sensors seem to read pretty close to correct for temp and humidity, tested against another mechanical gauge. In house readout is compact and attractive and easy to place where you can see it.. The sensors both use AA cells. Biggest issue will be how log they last as I have them located in not so easy a spot to get at, have two of them monitoring temp and humidity in a tight crawl space area. Won't be happy if I have to change the batteries too often.
