AcuRite 02446M Wireless Rain Gauge with Indoor Digital Display, Black

Good rain gauge. The receiver is pretty good (I got the vertical version) but I ultimately plan on using it with rtl_433, which it works great with. Range seems good. Can’t comment on battery life.

Very nice product. However, an interesting addition was that the display unit included 2 Kirkland AAA batteries and 1 Duracell AAA battery and the sensor had dust on the trip sensor.

If you use the correct force and removal procedure the plastic tabs on the outside unit will tend to not break. Ham-fisted or sloppy operation will likely break them. The batteries that are in that outside are very well protected if the installation procedures and suggestions are followed. Wireless Connection is easy, fast, and automatic if you follow directions. The display is easy to read and very clear. The unit auto-empties reliably. The measurement of rainfall, compared to other methods, is accurate and reliable. Mine stopped working and I removed the outer cup to get to the auto-emptying paddles within the outside unit. I had two spiders with webs that had taken up occupancy on the curved paddles. I cleaned them (the paddles, not the spiders) and used double-sided tape to attach a small piece of insect repellent plastic, harvested and repurposed from the Hot Shot 100046114 No-Pest Strip, on the inside of the cup to prevent re-infestation. I used a tiny bit of dry lubricant on the pivot point of the paddles at the beginning of the season to enhance the movement of the paddles. If the collection cup is left outside during freezing temperature, it will more than likely be ok, except that it won't work. There isn't any standing water left in the cup at any time due to the auto-emptying feature. The ports in the bottom of the cup need to be cleaned 2 or 3 times a season by running a pipe cleaner through them. I moisten the pipe cleaners with bleach to help keep the ports clean. It is an outside device, after all, and it is subject to getting clogged based on your installation point. With reasonable and easy care, ours has lasted three seasons with zero problems. Highly recommended except for one detail that, for me, is really annoying: the unit cannot be manually cleared. Daily rainfall from midnight to midnight is great. Rainfall from yesterday added to today is great. Weekly rainfall is ok. But what if you have a 4 day rain period that you'd like to know about? It would be great if there was a "clear" button that would manually reset the unit whenever desired. The cheaper version of this receiver has a clear button, but not this one. A very minor point, but, still a bit irritating. Remove the batteries to clear the unit works fine, but then the time and date and units, etc. have to be reset.

Update: This little rain gauge survived 120+mph radar indicated winds from the eye wall of hurricane Milton. Recorded 9" of rainfall during the storm as well.Picked up this rain gauge to replace my old sight glass style gauge that cracked. This one is easy to set up and use (no more moving it for the mower or algae growth from sitting with water). Did the calibration procedure described in the manual, out of the box it was within 0.01" of spec so I left it alone. Rain alert feature is nice if you need a warning at a particular amount of rainfall. Overall solid purchase for $30.The rain cup is mounted to the fence with a 3d printed shelf I designed for it. The file is free on Thingiverse if you wish to do the same.

Down to 1 star. Long story made short: Fiddled with calibration once again, tested the batteries (all good), totally reset the inside unit, and put it back in service. It rained the next day, glass rain gauge showed 2” of rain, AcuRite showed 0.3”. AcuRite gauge now resides in the recycle bin awaiting pick up. I’m wondering if all the people giving glowing reviews really know if the readings they are seeing are at all accurate.Good concept, easy set-up but questionable accuracy & lousy life.I would like to give this 3-1/2 stars, but that's not possibleI purchased this rain gauge in January 2003 (which puts it well beyond the return window). I went through the tedious procedure of calibrating it when it arrived and as it turned it was very close to the 1.68” number you are supposed to see so I put it service without any adjustment needed. The outside unit (rain gauge) is about 60’ from the inside display and there was no trouble in the two units connecting. For the last nine months or so, I thought I was getting super accurate readings, but to my dismay, it turned out I wasn’t.Living in Southwest Florida, we get the inevitable afternoon thunderstorms. We had two significant ones last week and my super accurate AcuRite rain gauge said there had been a total of just over 5”. HOWEVER, my next door neighbor who has one of those totally unsophisticated stick-in-the -ground glass gauges said he had over 8”.This prompted me to do two things. One, buy one of those unsophisticated glass gauges that you have to go outside to check which I did for about $13.00, and two, recalibrate my AcuRite gauge. After about five attempts of doing the 20 minute or so drip test, I was able to get it to read 1.70” which is within 1% and I figured that was close enough. The real test came the following day. We had rain and mu AcuRite showed .6”, but the outside glass gauge which is about 3 feet from the AcuRite showed 1”. My conclusion is that there is something wrong in the mechanism (at least mine) which can handle the drip, drip, drip, of the calibration test, but not a downpour that produces an inch of rain in 10 minutes which is not uncommon in our location..Pros: Easy to set up, like the concept of being able to see rain amounts without going outside, like being able to see today, yesterday, year-to-date etc.Cons: I’m a bit suspicious of the longevity/accuracy per the above.

Second one I have purchased. Don't bring it in during winter & we get "winter" So if I get 2 to 3 years (outside tracker) I am pleased. So if price does raise much in future, I will be back. Inside unit nice size and easy to read.

This is a replacement for a rain guage I had to empty to read how much rain there had been. With this, I don't even have to go outside and empty it! It simply collects and measures the rain, and drains itself. I read the amount it has rained so for each day -- from indoors! It keeps track of how much it has rained year-to-date and so far this month.Love it!!
