ESP-14 with temperature, pressure, humidity and light sensor
Hello,
I have an ESP-14 with a temperature, pressure, humidity and light sensor on one PCB.
http://www.ebay.de/itm/BMP280-Pressure- ... 1952174057
I successfully flashed it and can activate/deactivate LEDs, but how can I configure the I2C to have the access to the sensors? Does anyone have experience with that module?
I tried different settings and checked it with the I2C scan tool, but there is no connection to the sensors.
It would be a pity not using that device with espeasy. The sensors are already hardwired to the ESP-14 without using separate connectors.

Hello,
the ESP-014 uses an ESP8266 for WiFi and a separate microcontroller STM8003 connected to the ESP-chip.
I doubt if it is possible to get the sensors on the board running with ESPEasy as they might be connected to the STM8003-chip.

Re: ESP-14 with temperature, pressure, humidity and light sensor
Thank you, now I begin to see.
I flashed the ESP8266 with ESPEasy. I can use it, but only to activate some LEDs via wifi, which are connected to the GPIOs. The sensors seems to be connected to the STM chip only with no access via the ESP8266.
Now it is also clear for me, why the ESP-14 is not very common and less documented.
It means also that it would be better to use the ESP-12 (no STM chip). But I did not see a solution with the sensors on one PCB. Maybe someone will offer that in the future, because currently there are always approaches with different PCBs.

A couple of days ago, there was an article regarding the ESP14 on HaD:

Thank you, it helped a lot.
Is there a way to read data from the UART with ESPEasy?
I would like to:
1. programe the STM8, read the sensor data with that chip and send the data via UART to the ESP8266.
2. The ESP8266 has to read the UART data and forward it with ESPEasy over wifi.
The goal is to use ESPEasy together with FHEM, but how to handle the UART with ESPEasy?

Re: ESP-14 with temperature, pressure, humidity and light sensor
I think it is the same principle as the nextion HMI

Re: ESP-14 with temperature, pressure, humidity and light sensor
Did anyone make this board operational?
Do you have an example?
Thanks a lot

Re: ESP-14 with temperature, pressure, humidity and light sensor
Could you tell me what connection you made to upload ESPEasy. I managed to get a connection, but which pins shoud be pulled up or down to upload the firmware?waver123 wrote: ↑17 Feb 2017, 22:32 Hello,

Has anybody already got the sensors working?
