Ive started gardening and wanted to measure rainfall at my place to help me with watering the garden on a schedule or via home automation. I came across this Amazon deal on the Ecowitt GW2002 which uses the same sensor array as the GW1101 but has an upgraded gateway. Currently on sale for $135.99 with the Amazon coupon applied.
It's quite a bit more than the previous GW1101 deals but the newer gateway should provide better longer term options to scale.

My local BoM station is 10km away, so not a great representation of what's happening at my house. I can also integrate this into my Home Assistant to help schedule watering my garden and yard. Not sure a measuring cup can compare.

Walking will get you most of where you need to go but that doesn't mean you shouldn't opt for the better experience of a bicycle or car should you?

If bicycle or car help make you more productive and save time to do your job, then yes. Otherwise, waking will be cheaper and better for health.

Not really. That's not my use case. I'm not trying to predict weather. I'm trying to understand if I've had X mm of rain this week so far and therefore how much watering I should do. I do have moisture sensors throughout the garden but I'm finding huge variability so can't really rely on them.

@dealhunter52: Imagine if someone said 'people have been cooking with fires for thousands of years' on oh I don't know a deal about an induction hob? The vast majority of what we consume these days has been done previously without the newer tools but it doesn't mean it's redundant and useless automatically.

@dealhunter52: And I'm sure I could lick my finger, stick it in the air and measure the wind speed, direction and humidity

Yeah I found that moisture sensors are a bit dodgy. I have the gw1101 connected to my home assistant server and I run an automation to water at sunrise if there has been less than 10mm rain and if the bin predicts more than 10mm of rain. There’s also a heat factor that adjusts the s watering time depending on the max temperature the day before.

Dude why are you yucking someone else’s yum?
You shared a deal for a $48k car. Can’t you just get a $5-10k second hand car? Gets you from A-B just the same.

Key takeaway from your comment is most people need cars.
How many people actually need personal weather stations?

I think you can access semi local data on weather underground etc where neighbours publish? But very tempted by this. Is it a really good price / deal? I haven’t been tracking pricing on these.

everything needs to be connected to smart phones these days huh, this has been measured for centuries without all these gizmos

Well, you could opt for an external monitoring device but some may so that’s redundant when you have a smart phone, no? Or perhaps you want to see what the weather is like at your house from 2000 kilometers away?

Yeah I get it, BOM is all you need. Don’t buy the personal weather station. Easy.

@Broden: You understand wunderground only exists because of people using personal weather stations like the one listed above?

I suggest you look at PanTech on eBAy I've had three weather stations over the years and Pan tech have lasted me 7 years out in the elements , a little more expensive now but come with a color indoor screen and of course will automatically upload to numerous weather information pages if you want. Only need an app for initial setup .I have found mine to be really accurate and reliable.I think 7 years is a pretty good run and the only issue is if spiders setup home in the rain meter it won't work till you shoo them off.

Cool thanks will take a look. I really just want the cheapest option with a rainfall gauge so I know how much water my garden is getting. I'll then integrate it into my Home Assistant setup so I know not to water if I just got a decent downpour.

It's cheaper to stick your finger into the soil…

Just like it's cheaper to walk to work or to live in a tent

Cost nothing to stick it in your bum either but it doesn't mean it's right

Pantech are rebranded Ecowitts

Yeah, looks exactly like Ecowitt.

with a color indoor screen and of course will automatically upload to numerous weather information pages if you want.
From my research it is either indoor screen OR internet gateway. Not both.
But I don't have. If you have a screen you can check it for us - can you configure the data to be sent to wunderground too?

It's both of course .

Then don't get this, get a manual rain gauge, it blocks up often with dust, insects, spiders webs, kookaburras sit on it and crap, blocking the hole etc I'd classify it as useless and inaccurate as a rain gauge even when new.
I have one

I need to read up about how rain gauges work. I actually have no idea. My main need is to know if the downpour today was 2mm or 20mm, etc. so I can factor in whether to water or not

I have a backyard full of roses, shrubs, potatoes, orange, apple, apricot, lemons etc and have never bothered to water them and they turned out fine. Why is it critical to water when there is nature?

Depends where you live. Australian rainfall and sun exposure is extremely different across the country. Even shading from overhanging trees can have huge impacts.
Annuals have greater needs especially fruiting plants. Established perennials are generally adapted to the natural rainfalls. I don't water my lemon, apple or pear trees but I definitely water my vegetables

Even shading from overhanging trees can have huge impacts.
You'll need to get several then. One under the canopy of trees. One in the open. Maybe one in the front yard.

FYI my gauge overflowed (again). overnight i record over 30mm

Just a bit of extra information.
Ecowitt, Pantech, as well as the US based Ambient Weather are all retailer resellers of Fine Offset Electronics Weather Stations who are the actual manufacturer of these weather stations based in China.
Pantech is a good option as they are the local reseller here in Australia, so you get local support. But you cant really go wrong with any of these resellers, really depends on price.
It can be difficult cross referencing features as all 3 of these resellers as they all use different naming schemes for the various weather station models.
For example, I have been really keen to be a Pantech PT-HP2550 which is also known as the Ambient Weather WS-2000 (haven't been able to figure out the equivalent model from Ecowitt).

FYI OP I bought an Ecowitt recently, slightly different model to this (GW1101) but with the wifi gateway.. The HA integration is very easy.

my gw1101 has been going strong now for 4 years without even a battery swap

Im really surprised how controversial this device is. So many opposing views on buying or owning weather stations.
This crowd would be great at debating motorcycle ownership or other such topics.

Yeah I'm a bit surprised. seems a bit like some people feel they have to post on every product… If you don't want a weather station, or think they're stupid - you can just click on by!
My dad lives in the country - nearest weather station is a fair way away, and all readings and details from that are very different to his place as he lives at the base of a large hill which impacts temperature, rainfall etc. He's had an ecowitt for the last few years, and has found it reliable (has also had a couple of other temperature sensors etc., and compared temperatures to see if they're accurate and hey've all been pretty similar.)
I think the rain gauge uses a bucket tipper type arrangement - i.e. a small reservoir with a known volume fills up and then tips. When it tips, the gauge knows that a specific volume has been caught, and therefore (eg.) 1mm has been measured. And it basically just counts the number of tips.
I hooked his station up to wunderground and integrated it with my home assistant, so that I could talk to him about his rainfall (he's a farmer…)

Get this just to join wunderground
As much as I love BOM, wunderground is simply better in 99% of all cases for my personal use

Or, depending on how many users there are already around you, you could just make a free account and rely on the data your neighbours are uploading.

Awesome, thanks for sharing this - one of my neighbours has the full suite of monitoring. Saves me buying one! I wonder if I can take their data and ingest it in to Home Assistant…

I was thinking of doing the same. Closest is a few blocks away but a good stop gap. Let me know if you work out how to do it

These are good units and have great integration with homeassistant.
I have had my Ecowitt WS2910 for almost 6 years now and hasn't failed me.
It just requires a decent vantage point to be mounted (mine is on a pole off the top of a fence post) and a quarterly clean out of the raincatcher with a pipe cleaner and tissue. Occasionally a homeless spider decides to take refuge in the tipper cup and can prevent the rain from reading collection properly but the cleaning solves that.
I have a weather station. It uploads to WU. And my smart irrigation controller downloads the data from there. Since I’m in the tropics a thunderstorm can pour across the road and not rain in my yard.
