ECOWITT WH40 Wireless Self-Emptying Rain Gauge Sensor, Rainfall Collector - Accessory Only, Can Not Be Used Alone

easy to mount well made the accuracy against a known gauge shows reliable accuracy

Great app! No longer having to work at pulling rainfall on recent dates as the app records amounts by actual dates and not just by a number of days past. Precision of .01" is also a gotta-have feature over most other systems with .04" minimum measurement.

Worked off and on for 2.5 years, the biggest problem with it was birds pooping in it and spiders getting inside and building nests. I put a tiny bit of chlorine tablet inside it, that took care of the spiders and a red flag waving over it, that stopped most of the birds from using it as a landing pad and toilet. Now, the swivel shaft inside is rusted (see picture) and prevents the dipper from moving. If they would spend an extra dollar and use a stainless steel shaft, I would give it a 5 star. I found it to be fairly accurate by comparing it to the swimming pool level.

My husband loves this! He’s a weatherman at heart and he can see the temp outside the rain, it’s easy to use, easy to install, will definitely buy again if something happens to our other one!

After having several high-priced, big name weather stations destroyed by ant infestations, I decided to buy separate temperature and raingauge systems. Only the raingauge would remain at the location the previous systems had occupied, and it needed to be sealed against ants getting into the electronics. The ECOWITT WH5360B appeared to meet that requirement so I ordered one. I was delighted when I unpacked it. The unit was indeed sealed and except for the mechanical tipping bucket mechanism that had to be open to the rainfall, everything was totally enclosed in a plastic housing with no entrances for small pests. The tipper sent its tips to the electronics with a magnet, so there were no wires to be chewed and no holes for wires were needed.The assembly instructions, both the text and the drawings, were clear and easy to follow. All the necessary parts were provided except for the batteries (1 AA lithium for the sensor and 3 AA alkaline or lithium for the console). The console had no trouble locking onto the sensor's signal and it has never lost connectivity since I installed the sensor about 50 feet away from the house.The calibration feature deserves comment. Several reviewers complained about its accuracy and that had concerned me. This unit is exceptional in that it has an internal electronic calibration setting that can be adjusted any of three ways. There is a procedure presented in the manual using rainfall collected from the gauge after a storm, or you can pour known amounts of water SLOWLY into the gauge, or you can compare the reading with a nearby gauge of known calibration. Any of them will work. Unless your unit is actually malfunctioning, you should have accurate readings if you take the time to calibrate it.Both the sensor and the console look nice. The display is an attractive addition to the wall in our Florida room and we have been delighted with its performance.

This was designed by someone who had not heard of surface tension, followed probably by marketing deciding to sell it anyway after testing it. The basic problem is the funnel is far too flat and light rain simply beads up and does not flow down right away into the tipping bucket. Eventually droplets do coalesce together and get to the bucket, but the rain measurements such as hourly and rain rate are meaningless. I intended this to be a backup for my Ambient Weather Station (which BTW is well worth the money) in case its funnel clogged up. I also have a Stratus manual rain gauge for calibrating the station, so I have real, trustworthy data to compare it too.Presumably this gauge does better as the rain rate increases, but since it is totally worthless for measuring typical Seattle rain, I returned it before I got the chance to test that. Other reviews have suggested it is also worthless at very high rain rates. There might be some intermediate rain rates where it does ok, but you may never know when that is because clearly its acccuracy (using the term very loosely) is a function of the rain rate and surface tension of the funnel surface at the time it is raining.The one redeeming feature of this instrument (and is one reason I purchased it) is that it can be calibrated (in the software). However, other than that the display and software is only marginally ok. I never could figure out what the hokey bars on the left were supposed to show. But so what if the basic measurements are garbage...As for installation, it needs to provide easy ability to install to a vertical surface, as others have mentioned.For a country that can return moon samples to earth I expect a lot better.

The day after I received and mounted this we had a convenient rainfall. A friend who lives about a mile away has a high end Davis unit, he measured .21 inches of rain from this storm and I measured .20, essentially an identical reading.This device was carefully boxed and contains a 34-page, detailed instruction book, in all English and grammatically competent. A very nice presentation overall.The signal is very powerful. I get a full five bars in an apartment about 150' away, surrounded by cement walls and floors on all sides. I was able to mount the collector on an exterior fence open to the sky; my next move will be to put a very light coat of car wax on the collector to prevent rain drops from adhering to the collector (see photo).I do note that some folks have noted dramatic error readings from their units, for sure this needs to be placed well away from electronic devices, I couldn't get it to register at all when I tested it next to my computer and TV set, but on a bare wall it worked perfectly.Winter is coming and we'll see how this holds up during a midwestern ice and snow season. But for its first test on a rainy fall day, I couldn't have hoped for anything better.
