Thanks for the reply, although I don't understand what WH32E is or WH31 vs WH31E
WH32E - This is an outdoor temperature and humidity sensor that replaces the temperature and humidity sent by the WS80 or WH65 on the console as the primary outdoor temperature and humidity. This allows you better siting for the outdoor temperature and humidity. The WH32E should always be put in full sun inside of a proper radiation shield (do not use the RS-00001 though as it is terrible). You can only have one WH32E.
WH31 - This is an optional temperature and humidity sensor of which you can have up to eight of them. You can place them anywhere you like, indoor, outdoor, in the garage, attic, basement, bedroom, refrigerator, chicken coop...etc. But the WH31 will never be your primary outdoor sensor so you can't use it to upload to online services like WU or most others. The WH31 though does show up on Ecowitt.net, Ambientweather.net and on your own particular software like Cumulus MX, Meteobridge, Weather-Display, or WeeWX. Unfortunately Ambient has discontinued the WH31 and replaced it with the inferior WH31E.
WH31E - is a special version of the Ambient WH31. It is 100% compatible but it includes a Radio Controlled Clock (RCC) and it won't operate unless you are able to consistently get a good signal from WWVB in Colorado which is not always a reliable signal for many. Our stations do not need this RCC signal. The WH31E was meant for some other basic display consoles (not full weather stations) and thus in order to get time keeping they have this RCC. But it is a detriment to our stations that get time form the Internet. Poor decision on Ambient to stop selling the proper WH31 for our stations.
You can get all this information in this link:
https://www.wxforum.net/index.php?topic=40730.0I also didn't think I could buy the Ecowitt here in the US. Doesn't look like Amazon has the HP2551 at least...appears they have the GW1000.
Yes, you can get some models/parts on Amazon in the US from Ecowitt. But you can get *almost* the full line of models and parts from Ecowitt directly on their website or by email with then exception of 1 part (WS80). I suggest sending them an email to create a custom solution a excellent customer service. The exception and only part that they will not ship to the US is the WS80 because of a Fine Offset agreement with Ambient to have exclusive sales in the US for that part. But you could order everything from Ecowitt and then just get the WS80 from Ambient and it would all work (yes expensive but possible).
Also the HP2551 display console can be ordered separately from Ecowitt. Meaning you can get the GW1002 and then add the HP2551 display console if you want.
I'm torn between the having the console vs just having the app. On one hand, I'm used to the console, as is the rest of the family. On the other, I always have my phone.
Then don't be torn and get both (HP2551 and GW1000). Have as many display consoles as you want...put one in each room if you want. But do limit your upload configuration to online services to be from just one device, or else you'll create a mess.
One question, does the Ecowitt app show the PM25 sensor data? That's one thing I'm very interested in, living here in SLC.
Yes, if you are home (on the same LAN). Of you can set up a VPN to your home network and then have it anywhere. Or even simpler just go to Ecowitt.net from anywhere and there you'll see your PM2.5 and everything else. Or add your own software like Cumulus MX, Meteobridge, Weather-Display, and/or WeeWX (any or all of these) and then access that or use them to publish to your own website.
