Let's Control It

Hi,

I've buy the module bellow on ALI. I've loaded EspEasy R120 on the ESP-01 with my FTDI. It works perfectly, I can connect it on my wifi network.
I've try to setup my device with DHT11 but i've NaN value for the 2 measurements.

I've measured with scope on pin 2 of DHT11 and it still has 3,3v. Never low level to ask for DHT11 measurements.

Do you have an idea ?

thanks

Nobody uses this kind of module ?

Is it a puya memory?

puya ?

Please search the forum. A lot has been covered for this issue.

ok, puya version is an ESP-01 with puya parts.

I have to check on the module.

Yes, you're right. It's a Puya version.
So wath should I do ? There is a specific version of ESPeasy to load ?
Thanks

Yep, there is a special build for nodes with PUYA flash chips.
It has "puya" in the filename.

Puya version are only in pre-release (probably soon in stable) ?

what is the difference between ESP_Easy_mega-20180420_dev_ESP8266PUYA_1024.bin and ESP_Easy_mega-20180420_dev_ESP8266PUYA_1024_VCC.bin ?

The second one use the internal ADC to digitize the Vcc-Voltage and not the external signal from ADC/TOUT-pin of the ESP8266.
On ESP-01 the ADC/TOUT is not wired to one of the eight connectors.

so I have to use
ESP_Easy_mega-20180420_dev_ESP8266PUYA_1024.bin

Thanks

You can use both !

With the first one you can measure a external 0-1V signal, but with ESP-01 you must solder it direct to the (small) ESP-pin !

With the second one (_VCC) you can process the Vcc-voltage with a 'System-Info'-device. But with this firmware you can't measure a external signal on the ADC/TOUT-pin.

ok thanks.

I'll try to setup with the new firmware. Thanks for your help

So i've uploaded firmware but temperature is really strangely hight!

DHT11 (specially chnese clones) are not famous for their accuracy....

At this point...it's not famous....it's non-functionnal !

In fact I think the design of the board is stupid. The DHT11 measure the température of the ESP-01. I will try do dismount DHT11 and solder it on the other side of the PCB.

Hi,

I've the same issue, high vaules of both temperature and humidity.
Also the output is changing, but not as you would expect.
Did someone solve this?

I've remove (5cm far ESP) and replace DHT11 by DHT22. now it works properly.

OK thanks miralant.
problem is that the temp value is 15 degrees celcius above the real temp.
Thats a big difference between the +/- 2 degrees they should differ.
Did you just replace the DHT11 on the board and reuse the board where the ESP-01 is put on?

yes exactly DHT22 is connected on the same board but with 5cm wirings

Had the same issue here with this very small solution.
Solved it by bending the DHT11 to the outside of its board.
