Wow! I cannot imaging what such an amount of rain in a day would look like.
in the netherland you can buy this one as a alecto ws-1200 or wh0531 on ali
f.e. you can buy it at the GAMMA DIY
it has a 433mhz receiver
would it be possible to keep the 433 transmission for the standard display
and add the zigbee transmission ( rflink is the alternative, also posted here, but seems more work 
)
so splitting the signal or will it data only go one way
picture’s of the PCB
can someone post a picture of the backside of the wired version
i assume the red and green wire are the top and buttom of the S1 (connected to C5 and J3, haven’t multimetered as it is already in my movingboxes)

I think so, add two wires from each side of the reed switch (S1) to each side of the reed switch in the Aqara sensor. The red/green wires only apply to the water gauge device this thread started with, but you’re replacing that with another device (I assume that when the PCB in your post is inserted into the shell, it will register a magnet passing close to S1).
Interesting! Now that the raingauge I added in my post is getting quite expensive on Aliexpress, this is a good alternative, and even cheaper, with a screen included.
So my city had the biggest rainfall day in history two days ago 614mm, Just wanted to put in here that it worked perfectly and is as accurate as the local government ones. (and yes we have had severe flooding here in Brisbane Australia but all looks good now.

I just bought one on AliExpress. Also around € 25 incl. shipping to the Netherlands.
Also a nice way to calibrate the calculation of the sensor template in conjunction with the base station.
Hello
How can I know at all times if it rains a lot or a little?
So I can have the blinds closed with the intensity of the rain?
how long is the string
you could create a automation using the
if you have this sensor
from the first post here
sensor:
- platform: template
sensors:
rainfall_today:
friendly_name: Rainfall today
unit_of_measurement: mm
value_template: >-
{% set count = states('sensor.raingauge_tips') | int(0) %}
{% set mm_per_pulse = 0.30303 %}
{% set mm = count * mm_per_pulse %}
{{ mm|round(1, 'floor') }}
then the trigger would look something like
trigger:
- platform: numeric_state
entity_id: sensor.rainfall_today
above: 2
this will trigger when rain fall above 2 mm
option 1 just use the weather sensor
option 2 other trigger
trigger:
- platform: numeric_state
entity_id: sensor.rainfall_today
above: 0
option 3 weather sensor and have a condition that checks the rainfall today
- condition: numeric_state
entity_id: sensor.rainfall_today
above: 0
In an earlier post, someone showed how you can measure rain per hour
(Not tested)
ok, I’m using the sensor created in the first post, which tells me today’s precipitation, and it’s working. But it doesn’t tell me the real-time precipitation.
I may be misunderstanding, but if I use this tigger, if the precipitation exceeds 2 the blinds close and no longer open.
I wanted to know the amount of rain in real time. if now it starts to rain a lot the blinds close, after 20 minutes if the rain stops the blinds open.
How can I know this rain status in real time?
making cent now
off top of head (thinking on the fly here)
so what about creating a toggler helper input_boolean
which turn on when it starts raining and when the rainfall numeric_state changes
in the action part of the automation
service: input_boolean.turn_on
data: {}
target:
entity_id: input_boolean.its_raining
know the hard bit turning it off
just about think whats the off logic
could be a timer
could auto turn off after Xmins then if its been OFF for XX mins open the blinds
thats my thinking
Have you tried what I said above?
If you want to know if it’s raining right now, it would be best to buy this, and connect the Aqara to the two pins directly (this other board is not needed).
I’ve been trying what I said above, but I still couldn’t compile the code right 
this board I already bought 2 and it doesn’t work for a long time, it spoils fast
I ordered the rain gauge a while back, and I finally got around to pairing it with an Aqara MCCGQ14LM door sensor. I cut nice little slots for the wires to come out. Very pleased.
Now when I try to pair it with my Zigbee dongle I find that I need to upgrade the firmware before the MCCGQ14LM will work
I guess that’s my job for today.
Edit: Also needed to upgrade zigbee2mqtt for MCCGQ14LM support.

I have gathered all the parts for this really cool project! I have one question:
I am planning to use a solar panel and a rechargeable CR2032 battery to make this thing last longer without intervention. For this I have a solar charger module like this and I am wondering if I can wire the charger directly to the battery set in the sensor receptacle.
I still have to check what current and voltage is needed to charge the CR2032 battery and see if I need some sort of stepdown between the solar charger and the battery. Maybe an AMS1117 to bring the voltage down to 3.3 and hope that I do not destroy the battery.
Hi, great idea! But I’m not sure if that charger will work for a CR battery. It looks like it’s made for LiPo batteries.
do you know of a charger for a cr battery? if not I will replace the CR with a regular LiPo. I believe that the 3.7 v lipo will power the sensor without a problem.
I think the charger you linked to should work, LIR2032 (which is the rechargeable version of the CR2032) is Li-ion and the specifications of the charger state it can charge that chemistry too. However, I don’t know if you can charge it in-place, the charger circuit has a dedicated battery input and power output.
you are right! I didn’t consider that… then I should go the regular lipo battery (the one that looks like a pourch) and go that route. Or I could try to make a receptacle for the coin cell and charge it with the charger and solder some wires to the battery slot of the sensor.
So many options! Thanks guys!
