Ecowitt HP2553 vs HP3501
« on: December 01, 2021, 05:54:02 PM »

I am thinking about buying a PWS. After some research I conclude that HP2553 (Ultrasonic ) and HP3501 might be a good option.

In order of interest, it would be HP3501, as it has a WS 68 anemometer - conventional - what is unfavorable is the wind reporting time: it is only 16 Seconds from the sensor to the console while on the HP 2553 the sensor reporting interval is smaller: 4.7 Seconds
I have some doubts about the reliability of the HP2553 because it is ultrasonic and also the need to use heating if temperatures drop a lot, to avoid errors. Perhaps the WS 68 anemoter seems less of a problematic. :?:

But now another question arises, since data is sent to the WU every 60s, is it important to have a gap of 4.7seconds ?
I know that the vast majority of PWS have update times between 12 and 16sseconds.

The models I mentioned above, in addition they send data to WU, WeatherCloud/WOW, will they be able to send to a website that I create on a WIX  server or similar?
Thanks for your attention and help.

Not a fan of the Ultrasonic stuff. How bout a 3rd option as I prefer separate senors and the nicer console.

I recommend that you look at the stickies thread for direct comparison between consoles.
I will say this though that the HP3500 console is tiny, whereas the HP2551 console is colour and much larger and all round superior.

As for Ultrasonic/Wind cup debate, it all depends on where you reside. I am in southern UK, where overnight temps rarely go much below -5C and so far my WS80 has not dropped a beat and was a pre-production unit so does not even have a heater plate installed so I could not use it if I wanted to! I use it for my prime wind readings and it always is much more accurate than the wind cups sitting 12 inches away I use as a reference.
