I currently am using a Oregon Scientific WMR-100 with 1 wind, 1 solar, 1 indoor Thermo-hygro, and 2 outdoor Thermo-hygro sensors. The first outdoor sensor works in weather display, but the second outdoor sensor is not showing. My plans were to switch between the two sensors if the temperature rises greater than a certain point or set a time when Weather Display would switch channels/sensors. Since I live in a warm and sunny climate, channel 1 outdoor sensor is exposed to direct sunlight, even with shield, the temperature reads way too high. So my solution would be to place channel 2 outdoor sensor in non direct sunlight area, non-shady place but somewhat wide open, where the sun isn’t hitting during the hottest part of the day, the heat shield just doesn’t cut it during a sunny high UV day. I want to switch to the channel 2 outdoor sensor before the sun rises, so that during the day channel 2 would be reading rather than channel 1. Is this possible in Weather Display to switch between two channels for Thermo-hygro sensors, is it even possible to get the 2 outdoor sensor to work? Any help I appreciate it.
I figured out how to switch sensors in the Station Type options, now how do you switch sensors automatically?
would it not be better to just site one of the sensors better?
Not that easy on a hill in sunny weather almost every day of the year. Sensor 1 is facing the sun away from the hill on the roof but the sun hits it so much it gives inaccurate data. I will be getting an inaccurate reading if I put it towards the hill since the radiation and sun will hit the hill above making the temperature inaccurate. I want Sensor 1 on the roof night exposed where the wind and exposure to the night sky will give a more accurate reading during night, but want Sensor 2 away from direct sun light during the day, somewhat in the open but half shade half sun. I can just use sensor 2 all day but its 2-5 degrees off during the night due to being less exposed to night sky.
I think its just too much of a stretch to add this to the software, when its likely to be hardly ever used by anyone else
just my thoughts
The usual solution is to improve shielding of the sensor. There are many ways to achieve that, ranging from a ‘professional’ Stevenson Screen to something home made. Here’s an example of a popular approach.
Yep, this software isn’t that great for multiple sensors, hopefully new versions fix that problem, but i notice the Weather Underground Uploader has the ability to tweak the temperature during certain times but it still doesn’t have an option to switch the sensors. As for shielding the sensor, with the radiation coming from the hill, only way to prevent that is putting the sensor in the shade area which will give me an inaccurate reading of the night time temperature but correct reading of daytime temperature. I already have a heat shield over it as well as the shield that comes with it, but maybe i’ll try to add a fan. I wish I was a programer and could add those options to the software, but I don’t use weather display anymore because I had problems with my WMR-200 communicating with it anyways.
