Seth,
that's actually pretty easy to set up. My python script on the RPi runs in
an endless loop, waits for a bucket tip and only writes the cumulative
number of tips (ever) to a file and calculates the rain amount (total,
cumulative) by multiplying it with the bucket size. Before that, it
Could you share the programming for that? Maybe you have it on Github?
Right now I have everything running on an RPi because the weather station
is remote. But eventually I'd like to have Weewx running in a virtual
machine, and the bucket will get connected to a RPi Pico and report the
tips via
Good to know. The RPi where the bucket is connected to is actually not the
machine I run weewx on. I run MQTT to feed the (collective) rain amount
into weewx every time the bucket tips. My "main" weather station, if you
want to call it that, is a Ecowitt GW1100 with an outside temperature
I've been happy with mine. Ecowitt sells a bird spike kit that fits it very
well.
The only downside is making the bucket play nice with whatever driver
you're using for the main weather station. I created a service to
accomplish this, which is linked in this thread. Come to think of it, I'll
Thanks a lot, Seth!
I do it similarly in python: from gpiozero import Button
That button routine in the gpiozero library already has a debounce function
and I only count on "close" and just ignore the "open". So far it works
well, but my current gauge only has a 5 * 11 cm opening (=55cm2),
The Rain wise bucket is .01" / .254mm, and in testing it that has been
accurate. It's more a matter of leveling the buckets once mounted, but it's
not a difficult procedure.
And yes, it just acts as a button/switch. I used the gpio library because
it easily allows for treating the bucket like a
Seth,
Reviving this thread since I currently run a very similar setup. However, I
have a rather el-cheapo rain gauge and was looking into replacing it with
something more accurate, like the Rainwise RAINEW 111.
Supposing you did calibrate the gauge, what bucket size did you arrive at?
Like,
Helps a lot, thanks. I kinda figured you had other power that you're just
piggybacking the pi onto. Cool project.

One wire to the chosen GPIO pin (set in weewx.conf) and one to GND.
Nope. I might keep it for a future project, but not used here
Yeah I'm guessing it's just because the wire is not direct burial rated.
I'll be routing mine through PVC
I keep it in a shed in the orchard. All components are
Pretty cool. Dumb questions follow.
- how'd you wire it up ?
- did you not use the little display that comes with the gauge ?
- their manual says 'wire cannot be buried' - any idea why ? What if
it was in a PVC conduit ?
- what does your zeroW setup look like for powering
Got it working!
This allows you to add a wired rain gauge to WeeWx via the GPIO pins on a
Raspberry Pi. Thanks for the help!

Fantastic, Thank you! That's exactly what I needed.

By the variable config_dict you find in __init__. It is a dictionary the
represents weewx.conf. For Example the section [Station] you find as
config_dict['Station']. The entry
You're probably going to need to write or modify a driver. The great thing
about Weewx is that it's python and you have all the code. Check out the
docs here: https://weewx.com/docs/customizing.htm#Implement_the_driver

Thanks Glenn,
I'm not sure the OWFS solution is much simpler than just programming a
counter for the gauge. What I don't know is how you take that count and
insert it into WeeWx. This is partly because I'm not sure how WeeWx
processes data from rain gauges, and I don't know how to get into the
Regarding the Rainwise rain gauge and OWFS.
Yes and No.
It is NOT hooked up directly to the Pi, certainly not for the OWFs driver.
I see there are various HowTos about interfacing a reed switch rain
gauge to a Pi using that method but until you find one that's proven
and tested (bug free), or
Hello, my searching thus far has been fruitless.
I'd like to hook a Rainwise RAINEW 111 wired rain gauge up to WeeWx running
on a Raspberry Pi Zero W. Does anyone have any experience with this?
