Hi!
I bought a weather station that includes an external temperature/Humidity sensor as well as a rain gauge - for 6.99 EUR.
Here is the link: https://www.amazon.de/dp/B07DPFJ4RC/ref=cm_sw_r_apa_i_YVy0EbPX8FF9J
Did anyone ever integrate these sensors, especially the rain sensor?https://github.com/dgomes/homeGW
Unfortunately I can’t find a product number or so so I have to wait for the package to arrive so I can maybe find it on there.
It’d be awesome if this cheap set could be connected via Sonoff Bridge or any esp8266 and then transmitting the data via esphome or mqtt.
Thanks
I’m using a few digoo temp/humidty sensors with
Please report back if you get it working.

I have 12 of the Digoo DG-R8H temp/humidity sensors, using them with rflink. But not all Digoo 433 temperature/humidity sensors works. E.g. the Digoo DG-R8S is known not to work. So I’m interested too.

So I received the weather station on friday (some delay in the parcel stations …).
Basically, it’s a nice set which is working pretty good but unfortunately, I’m not able to get the sensor values into HA yet.
Currently trying it with a DVB-T stick using https://github.com/james-fry/hassio-addons/tree/master/rtl4332mqtt but log only provides the following:
[s6-init] making user provided files available at /var/run/s6/etc...exited 0.

I’d use rtl_433 from merbanan but I don’t want to use another Raspberry for this as I’m running on hass.io .hass.io ?

To see if rtl433 works you can install it on Windows. If it doesn’t work, you have no time lost trying to install on your Pi.

Ooops, sorry, totally forgot this topic.
I also ordered one and got it working with rtl_433 on a raspberry.
I’m running rtl_433 wit the following command.
/usr/local/bin/rtl_433 -F json -M newmodel -R 08 -R 19 -R 52 -R 129 | /usr/bin/mosquitto_pub -h ha-vm -t home/rtl_433 -l
The -R 19 is the protocol for the temp/humidity sensor which works out of the box.-R 129 protocol.
Here’s what i get in the mqtt topic for the gauge.
20200617 20:38:17 - home/rtl_433_demux/Eurochron-TH_30 {"time" : "2020-06-17 20:38:16", "model" : "Eurochron-TH", "id" : 30, "battery_ok" : 0, "temperature_C" : 3.200, "humidity" : 0, "button" : 1}
The `temperature_C’ value needs to be multiplied with 3 and then shows exactly what’s on the display of the station.
It’s a bit tricky because the gauge resets this value from time to time, but with a few template sensors and automations, it works.
EDIT: I think the outdoor sensor alone is worth the money. The first one I saw with screws and rubber seal for the battery cover.

Here’s the whole package if anyone is interested.
First, i’m using Taras (@123 ) MQTT Demultiplexer for the mqtt topics. See automation below.
I want to have daily values, so i save the total value from the gauge to an input_number at midnight and subtract it from the raw data of the gauge.

Thx @VDRainer
Got it working (getting MQTT data) without another raspberry by using https://github.com/james-fry/hassio-addons/tree/master/rtl4332mqtt with the protocols provided by @VDRainer .
My config is:
mqtt_host: 192.168.0.ZZZ
mqtt_user: YYYYY
mqtt_password: XXXX
mqtt_topic: weather/station
protocol: 129
frequency: 433920000
gain: 0
frequency_offset: 0
Also, to be able to find the correct MQTT topic (it’s not just what you set in the config), you need to enable mqtt logging by uncommenting line 183 in rtl2mqtt.sh
BTW: I downloaded rtl2mqtt.sh via wget to /config/rtl4332mqtt as I had problems with starting the addon first.
@VDRainer Any idea how I can set both, protocol 19 and 129, in config?
1 Like
No clue how the addon works, but if i look at the rtl2mqtt.sh, i see the rtl_433 command.
/usr/local/bin/rtl_433 -F json -R $PROTOCOL ...
Maybe for testing change it to
/usr/local/bin/rtl_433 -F json -R 19 -R $PROTOCOL ...
and ask the author of the addon howto add multiple protocols in the addon config.

Yeah that worked, thx.
But I’m getting negative values for the rain gauge like -20.100 in weather/station/Eurochron-TH/46 and high numbers like 38.400 in weather/station/Eurochron-TH/170
Do you also get two seperate IDs from the Rain Gauge?
You’re right, now that you say it, there are multiple of them.

The last one shows the values that reflect the display.
Could it be that there’s a backchannel from the station to tha gauge?
Did the neighbor also buy one?

So, I just got one of these and am just playing with it. The data is confusing… Nexus-TH is straightforward and gives the correct temp and humidity but what exactly is the Eurochron_TH telling me?

Should be Eurochron-TH temperature_c with ID 10 multiplied with 3. (IDs differ per unit)

I only have small amount of data so I am guessing here but,
Is it possible that:
Eurochron-TH id: 71 - Could the humidity figure be the Nexus-TH Temperature x 10?Eurochron-TH id: 10 - Could the temperature figure be the Eurochron-TH id: 71 Temperature x -10 (to one decimal place). But what either of those temperature figures actually relate to I have no idea.
And,
Could the two button figures indicate which way the tip bucket is sitting?
And, I’m wondering/hoping the Eurochron-TH id: 10 Humidity figure might be a measure of rainfall. We have had none here for days (but I do have a reading for 2 days ago of 5.7mm from when I was tipping it by hand to test it).
I have a couple of confirming instances of the above data but as I said not enough to really be sure.
Here is another one:

Well the Nexus-TH does not have to be calcluated to provide temperature and humidity data.
No idea about Eurochron-TH 71 but Eurochron-TH 10 temperature *3 = amount of rainfall.

Yes, the Nexus transmits actual temp and humidity.
But your suggestion of the TH-10 temperature * 3 being rainfall doesn’t tally with my readings.
I have had no rain for the last three days and four days ago I have a reading of 5.6 because I was playing with the tip bucket.
3 * TH10 Temp = 6.6
??

Try resetting both, the sensor and the display.
I also started to receive the correct values (when multiplied *3) after resetting.
