AVATTO S06 Pro Tuya

[interkom]

Good afternoon. I bought an infrared WiFi remote control AVATTO S06 Pro Tuya with temperature and humidity sensors.

I can not find information on it on the network. Is it supported by Tasmota?
Exactly the same without temperature and humidity sensors, I upgraded to Tasmota and ESPHOME, but I can't flash with temperature and humidity sensors.
I can't even figure out which microcircuit is connected to the ESP8266 and on which bus? What kind of temperature and humidity sensor is installed in this device?
Nothing is written on the microcircuit, but it is written on the sensor, but very small, I could only read AH10 A12113. If anyone knows where to get the documentation for this device or how to flash it so that the temperature and humidity are maintained, send a link.

[sfromis]

Devices known to be Tasmota supported are listed in the templates repository.

I do not recognize that sensor name, closest I know is the I2C temp/hum sensor AHT10, which is also what's stamped in the metal can of one I have. Thus it does not appear to be what you have there. Many sensors are I2C, but several relevant ones are not.

Tasmota supports a number of pretty standard IR pucks, but none with a T/H sensor. "Someone" may have to work out how your device is built, what pins are used, and if the sensor is a supported one (or maybe create a driver if not).

Thank you very much

Hope my experience below can help you.

I've bought this one and obtained WB3S chip instead of ESP8266.

Here is the pins description I've researched:

Replaced WB3S it with ESP12-F:

There is a AHT10 temperature/humidity sensor is used (bottom left on pic). I've removed TuyaMCU chip and closed SCL/SDA pins on PCB directly to ESP8266. It works great with AHT1x Tasmota driver #define USE_AHT1x for my 2 Avatto devices:

See command 'WebButton'

[leeza1971]

See command 'WebButton'

Command "Webbutton" is for changing the names shown on the web button.

My question was how to assign function to the Web buttons.

In tasmota, when you assign a relay to a GPIO, a web button appears on UI with ON/OFF label above the button indicating the state of the relay while the button itself has the label "Toggle".

The command "Webbutton" is to change "Toggle" to whatever the user wants.

Here, in the above pic, the web buttons do not have ON/OFF label and it seems that each button has a certain function like AC set cool", "AC set heat" and so on.

My question would be how to create buttons without "ON/OFF" label above the buttons. I know that assigning a certain function to a button can be achieved by rules...but I could not figure out how to create buttons without "ON/OFF" label thereabove.

Newbie here. Where does this code get inserted? Berry Scripting console? Added as a new .json file?

[sfromis]

It needs a special build with the scripter feature to support that language. Something similar could be done with Berry.

[modicon1]

Do you still have the custom firmware for the ir controller and the AVATTO S06 Pro temp sensor? If so would I be able to download it. I have the identical setup and I modified the board as per your instruction

[Onepamopa]

Same here.. Is there a prebuilt version we can use?
Tuya S06 Pro with AHT20 sensor, the chip is BK7231T (WB3S) (no idea if it's supported in Tasmota)

From what you are saying it sounds like I have no choice but to upgrade using serial. :-(

Any tips on reducing the size of my custom binary?

[sfromis]

Well, the link I posted is for such a case, without breaking open and soldering.

[modicon1]

Thanks. I'll give it a shot and let you know how I make out.

[modicon1]

Well... After I figured out that the updater can't handle .gz files I managed to upload my binary. The problem is that the upload over wrote the WiFi credentials and didn't give an opportunity to reenter them. So now I can't communicate with the device.

Any suggestions before I desolder the chip again?

[sfromis]

If you got it done using the right binary, I already mentioned:

you may have to configure from scratch again, connecting to the Wifi AP being broadcast.

And a .gz binary is only for OTA upgrades of Tasmota, not this "emergency procedure". If that was the last one you updated to, no recovery.

[Onepamopa]

For some reason I'm unable to flash it, gives an error ..... Everything looks soldered good, but...
Tried using the arduino IDE, getting only:
Serial port COM5
Connecting.................._____

[modicon1]

When you updated to tasmota.bin did you retain your wifi settings? I used Updater as you described and it work for me as well. The problem was when I updated the Tasmota firmware to tasmota.bin from updater I lost my wifi credentials and could no longer communicate with the device using wifi.

[sfromis]

Yes, "did not even lose my config" includes Wifi. But if the config is lost, Tasmota is usually able to go into initial config mode, broadcasting an AP to connect to.

[modicon1]

So Tasmota automatically broadcasts an AP SSID when it loses wifi config?

[sfromis]

If it loses config as such, meaning not finding a settings data structure with a correct checksum, it should treat it as a fresh flash, and do a full initialization, which includes the standard AP mode. The binary tasmota-minimal can't do this, but needs a working config already.

If it for some reason has bad wifi setup, the usual recovery techniques might be relevant.

[Onepamopa]

Do note, on these S06 Pro's ... the Tuya mcu needs to be removed before initially flashing the ESP, else it won't flash. You can re-solder it back after initial flash, it's useable.

[abuhabeeb]

I have S06 Pro with AHT20 sensor, I mange to work it with ESPHome it shows the temperature and Humidity, I tried with Tasmota but labels and values do not show up .
When I do a I2cScan from the console, it shows {"I2CScan":"Device(s) found at 0x38"}
The command I2CDRIVER returns {"I2CDriver":"43"}

Added to user_config_override.h

#ifndef USE_AHT2x
#define USE_AHT2x       Enable AHT20 instead of AHT1x humidity and temperature sensor (I2C address 0x38)
#endif

#define USE_IR_REMOTE                            // Enable IR remote commands using library IRremoteESP8266
#define USE_IR_REMOTE_FULL                       // Support all IR protocols from IRremoteESP8266

Anything else I miss?

@modicon1 Did you manage to make it work with your S06 Pro with AHT20 sensor?

[modicon1]

Abuhabeeb I did everything as you described except for esphome but never got it to work with the AHT20. After much back and forth with the team I finally gave up. When I get back home in about a week, I am going to swap the AHT20 for an AHT10 and be done with it.

[modicon1]

I suspect there might be a bug with the AHT20 sensor driver. I physically replaced the AHT20 with an AHT10 sensor, updated the .bin to #define USE_AHT1x instead of #define USE_AHT2x and Humidity, Temperature, and Dewpoint showed up on the Tasmota UI as expected.

[excodex]

@abuhabeeb hey, can you please share your esphome config? thanks!

[marsman7]

I have also converted the Avatto PCB to ESP8266 and it also works. By default, the operating voltage of the AHT10 sensor is switched via transistor Q5. In the description above, this is bypassed. Does Tasmota offer a way to switch the sensor on, retrieve data and switch it off again? This minimizes the self-heating of the sensor.

[sfromis]

No, but the "problem" with heat and sensors is usually not the sensor, but the Wifi device generating heat, spreading inside the case to skew what the sensor gets.
