I stumbled across the TuYa TS0201 temperature and humidity sensor while looking for a simple humidity sensor.
Actually, I was looking for a simple humidity sensor with display to display the humidity in the basement. The background was that I wanted to ensure that the stored boxes, files and all the other typical basement stuff is not too damp and possibly mold can develop.
The cool thing about the TS0201 is that it doesn't just display the measured values. He also sends them to you via Zigbee SmartHome. For example, you can have the measured values monitored automatically. Conceivable would be, for example, an alarm as soon as the room temperature exceeds a certain limit. (An example of this I have in the article Node Red - High Humidity Warning described.)
How to put the TuYa room temperature and humidity sensor TS0201 in your Node Red entity or cigbee2mqtt and read out the data, I have described in the following article.
Safety instructions
I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.

Requirements
Helpful articles:
Before you start this article, you should have prepared a Raspberry Pi so that it can be reached via the network and controlled via SSH. Of course, zigbee2mqtt and Node Red should also be installed and configured.
The following articles describe what needs to be done to prepare the Raspberry Pi.
- RaspberryPi – setup for nerdiys!
- RaspberryPi – The first configuration!
- RaspberryPi – Control the RaspberryPi via SSH
- NodeRed – Installing NodeRed on the RaspberryPi
- Zigbee - Installing zigbee2mqtt on the Raspberry Pi
- Zigbee - register devices, sensors and actuators with zigbee2mqtt
In the following lists you will find all the parts you need to implement this article.
Required tool:
| Number | Link |
|---|---|
| 1x | Screwdriver set Buy at Amazon |
| 1x | SD card reader Buy at Amazon |
Required material:
Log into the NodeRed configuration interface
Before you can edit your NodeRed configuration, you must - if activated - first log into the NodeRed configuration interface.
Enable Zigbee2mqtt Dashboard
In my opinion, the easiest way to add new devices to your Zigbee network is to use the zigbee2mqtt dashboard. In case you haven't activated this yet, you will find helpful hints in the article Zigbee - Administration of Zigbee2mqtt via the dashboard.
Register sensor to zigbee2mqtt
Before you can evaluate the sensor using NodeRed, you must of course first integrate it into your Zigbee network.
I have a little more detail on how to integrate devices into your own Zigbee network in the article Zigbee – register devices or sensors and actuators with zigbee2mqtt described. The following two steps summarize this briefly.
To put the sensor into pairing mode you have to insert the battery and press the button on top of the sensor.
- Press and hold for approx. 5 seconds
The signal indicator in the display should then flash. The sensor will then connect to your Zigbee network shortly afterwards. You can recognize this by the fact that the SIgnal display stops flashing and is displayed permanently.
You can track the status of the connection process in the zigbee2mqtt log.
Import node code
The dashboard node should already be installed and configured so that you can also control your Zigbee device via the NodeRed dashboard or display the values. You can find information about this in the following article.
After that, all you have to do is import the NodeCode linked below into your NodeRed environment. Information on how to import NodeRed code can be found in the article NodeRed - import and export node code .
As always, you can find the NodeRed code in the Nerdiy Git repository under the following link:
Natürlich müsst Ihr den Code noch an Euren Sensor anpassen. Damit dieser korrekt funktioniert müsst Ihr noch die IEEE Adresse bzw. den “friendly Name” Eures Sensors in den NodeRed code eintragen.
Öffnet dazu die Eigenschaften der markierten Node und tragt eure IEEE Adresse im markierten Bereich bei “Payload…” ein. Wie Ihr die IEEE Adresse Eures Zigbee-Geräts herausfindet ist im Artikel Zigbee – register devices or sensors and actuators with zigbee2mqtt described.
In order for the update function to work via the NodeRed Dashboard, you must also enter the address here in the highlighted area.
You can of course also use the newly registered Zigbee device via the zigbee2mqtt Dashboard control or read out.
In the following category I have also listed other Zigbee devices which can be controlled or read out with the NodeRed code offered there.
More articles on the topic
I have summarized other articles on the subject of Zigbee and zigbee2mqtt in the following category. There you will also find articles on various Zigbee devices and how they look like NodeRed can be controlled.

Have fun with the project
I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. 🙂
PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂

But the sensor is quite expensive. Much cheaper and more suitable for several rooms seems to me:

for currently 13,81€.
The firmware on it is Tuya. Maybe also in the one you presented, but that's not exactly clear from the article.
Frage: Läßt sich da Tasmota draufflashen. Und wenn ja wie bzw wie sind dann die Einstellungen vorzunehmen um es als Tem/Feuchtigkeitsensor über Zigbee zu parametrieren? Oder ist ZigBee immer unabhängig von der Firmware und kann mit jedem ZigBee-Dongle/-Hub betrieben werden? Wobei immer noch die Frage bleibt, inwieweit die Tuya “nach Hause” berichtet. Insofern wäre z.B. Tasmota o.ä. schon angenehmer
Hi Konrad,
yes there are now several sensors that offer the same functionality. Thanks for the hint.
The firmware on the Zigbee sensor cannot be replaced by Tasmota. Tasmota was developed for the ESP family. The sensor most likely does not use one from the ESP family, as it does not support the Zigbee protocol and also consumes significantly too much power for continuous battery operation 🙂
The sensor cannot call home alone, because it is only connected to the WLAN via a Zogbee bridge. This means that the sensor itself does not have direct access to the Internet. 🙂
Best regards
Fabian
