Impossible to see Tuya TH01

Configuration
1

Hey all. I just got three Tuya temperature and humidity sensors. Wanted to add them in HA, and went down the loop of Tuya local, as otherwise I won’t see neither temperature nor humidity.

Developer platform setted, app setted, now I see my devices on the phone and on the developer platform. On the developer platform they result online, working, can see everything. On the phone I can see the changes and the devices.

However… I DON’T see them on my network in anyway, I have no way of finding the devices’ IP adressess, neither in the router nor in the app, I get a connection error. So I have no way of finding the IP addresses to use in the app.

Any suggestion? Any idea of the why?

P.S. My router is the ISP one, pretty basic, but always shows IP addresses.

Perhaps they are not connected to your local LAN (your WiFi network) or left that network for some reason? Or maybe you initially connected them using Bluetooth mode but not using WiFi mode?

Try to (re-)connect them to your your WiFi network. Make sure your phone is connected to the 2.4Ghz network but not to the 5Ghz network when doing this!

A step-by-step guide about how to connect these Tuya TH01 devices to your WiFi network you can find HERE (follow the paragraph about WiFi Mode).

Note that by resetting/reconnecting these Tuya WiFi based devices they will get new keys assigned to them.

So I found the issue and it’s getting complicated.

Apparently to save battery they connect to the network for a few seconds every 2 minutes to update the data and then they’re gone.

So, now… How do I get in HA? And how do I make them show the data constantly? Any idea?

Someone found a way to get around that deep sleep issue involving specifying 2 dp points within the config screen of local tuya for these sensors and then creating two automations which can be used in your cards, automations etc. Just use the search mask of the forum and you will find that thread.

Great, will look into it.

Ehm… What are “2 dp points”?

Tuya use “data points” to communicate internally with the chip. Search for “TH01 data points” and you should get a few hits.

Found the thread, thanks! Now I need to understand how he got the devices on the network and I should be good.

Hi, did you manage to read the values ​​from TH01?

I currently have a problem with this too, I noticed that by pressing and releasing the reset button, the sensor appears in the local network and I can add it to HA, but it does not detect data points - Connection to device succeeded but no datapoints found, please try again.

I tried configuring DP for 1, 2 and 27, 46 (in API explorer on tuya platform I received temp_current with dp_id 27 and humidity_value with dp_id 46).

Every time in the entity I had the status Unavailable (it did not read anything and the trigger had no way to activate)

I’m also struggling with my “Tuya”
“name”: “Temperature and humidity sensor”,
“product_id”: “pvw2gbuqkfufedmz”,
“product_name”: “带屏幕温湿度传感器 Wi-Fi”,

device, the situation is similar: the device is communication with Tuya cloud, it seems it’s conserving energy by disconnecting from wi-fi.

I tried to at least get the IP by tracing my DHCP logs, but funny enough, I cant finf a single DHCP request from the thermometer’s MAC in whole 24 hours, despite it sent several reports to the cloud in this timeframe - WTF?
