from M5Stack I got the answer that the function "uint16_t getCalCurrent(uint8_t channel);" is not available and they removed it from the source... I am sorry but I don't understand how to use the function to send a command. I need this to send the value "1000" for calibration (fo...

Hello, I am back and got new devices. Unfortunately I had 5 wemos s2 mini which are not original, now I have one directly from wemos and made a test with that device. Unstable wifi is horrorable, I guess that I got shitty boards. In future I will use different boards than s2, but this firmware only ...

I have two esp32-s2 boards here (wemos s2 mini) and both loose the connection all the time... I don't know why but I cannot test with these boards, I ordered new ones today. I have here in the same room and around 4 other ESP8266 running with no connection losses, never, so I guess wifi is ok and th...

obstbauer

for a first test to read out the firmware version, I get value 0, so I think it is wrong at the moment it is difficult to make tests with this wemos device because I loose the connection a lot of times, don't know if it is a problem of my wifi or of the device.... 126438: WD : Uptime 2 ConnectFailur...

obstbauer

ok I can use it now... thanks
for a simple first test without current source I want to read out the i2c adress, is this command correct ?

Code: Select all

read.u8le.0xFF;

or to get the calibration current

Code: Select all

read.u16le.0x30;

?
Because for both values I get 0 at the moment
I2c scan finds the device at 0x55

I am sorry, I am not able to flash my wemos s2 mini and I don't understand why.... I was able to flash it online with a normal ESPeasy Version, the ESP Easy Flasher find the device as COM4 but there are always errors.. I tried it with two boards. If I try my C++ programs with Arduino IDE the USB con...

obstbauer

woah thank you

obstbauer

it would be nice to have an easy wired serial connection, because I have no experience with c++ and wifi and I want to keep it as simple as possible, both devices are close together

the sender is the ESP with my own software, the receiver ist espeasy, one value around every 5 seconds

obstbauer

is there a simple wired communication possible between two ESP32, one with espeasy? Over UART for example ? I had an ESP32 running now with the M5Stack device and I get the current values, I want so sent them wired to another device with espeasy which makes the communication to wifi and show values ...

obstbauer

First question: How can I find out if the generic i2c interface plugin is available ? Second question: Is ESP-now available meanwhile? Then I could use on ESP for the i2c communication with a simple C programm and sent the values to another ESP which shows the values on a display and communicate to ...

obstbauer

woah this was fast, how can I get the plugin to test it ?

obstbauer

there is code available for communication

https://github.com/m5stack/M5Module-4-20mA

obstbauer

ok.. not nice news, I don't think that I am able to write a plugin... I thought that there is maybe a solution with a rule or something else to build an i2c communication with the mentioned protocol the resolution of the INA devices are not so good with 0,4 mA and 0,8 mA, the m5 devices are really n...

obstbauer

Ok thank you, but now I have the m5 ones and it would be nice to use them...

obstbauer

Hello, I would like to use this 4-20 mA measurement device with i2c but I don't know how to communicate with it to get the current values https://docs.m5stack.com/en/unit/AIN4-20mA%20Unit I think it is not included up to now to the plugin list? Is it possible to talk to it with esp easy ? i2c protoc...

obstbauer

it works,
thank you for help !

Mr. Ali tells me that my displays have SH1106 chips, so maybe this is the problem?
How can I find out which chip is on the display?
On the display itself I cannot find an information about the chip

How can I change the brightness ? I found nothing in the esp easy config ? I can change the contrast ?

obstbauer

thank you
but my display only works with "OLED SSD1306" with "OLED SSD1306/SH1106 Framed" it doesn't work,
the preview is correct but on the display is shown nothing except random pixels
here is my setting:

Hello, I have a similar problem. I use a 128x64 1,3" OLED Display with en ESP32 C3 super mini Build: ESP_Easy_mega_20240414_normal_ESP32c3_4M316k_CDC Apr 14 2024 With 8 rows the signs are too small. There is no other font than optimized and normal ? I want to have 4 rows which changes like Room...

it works!
Thanks a lot !

Hello, I try to control a fan with measured humdity, PWM and rules but I don't find a working solution. I know how to do it with python or C but I have problems to understand the rules logic.

the sonoff adapter is for tasmota And I started with tasmota and then I made first tries with ESP Easy and the esp easy devices worked with this sonoff adapter so I did not expected that there is a problem it seems to work with values from hardware (because I only worked with temperature and humidit...

obstbauer

ok problem solved....

I had no real mqtt server installed for iobroker
I always used the sonoff adapter to get the values and it works with my other esp01 and esp32 devices
I don't know why but I get the values
I installed now the mqtt server adapter and now I get the adc values

obstbauer

@ Ath:

Sorry I don't understand what you mean?
I have some ESP_Easy devices running and the values are shown in my iobroker with mqtt like this:

on the pictures above you can see that with my adc problem device the values are not shown and there is no option to find or see the values?

obstbauer

I made a test with a second Lolin NodeMCU V3 board and with the free RAM measurement and it is the same problem
the mqtt connection is ok with both boards but no values only indicator reachable true....

obstbauer

this is the entry:

obstbauer

no other idea?
It is sad because I cannot use this bord for logging my pressures

obstbauer

Yes send to Controller is enabled

obstbauer

I use the A0 pin ?
I Think this board has only one ADC ?

obstbauer

I erased the device and installed the Build: ESP_Easy_mega_20231013_normal_ESP8266_4M1M Oct 13 2023
the pressure measurement works fine but I have exactly the same problem only the indicator.reachable signal true arrives iobroker but no values ???

obstbauer

ok, I will try it
there is no blank 4_M filge available?

https://td-er.nl/ESPEasy/

obstbauer

I have additionally a wemos S2 mini running and communication with iobroker is no problem too
with the same settings in the controler

obstbauer

subnet is the same
all esp have different IDs
you can see on my screenshot above that the iobroker see the ESP but there are no value so in principle comunication is available

obstbauer

subnet is the same

obstbauer

with 1000 ms same problem

obstbauer

I have three ESP01 which all sent their data to iobroker without problems
and I use the same settings of them for this devide so I don't think that the controler setup is a problem?

obstbauer

no
no values are shown
only indicator reachable on the picture I posted

obstbauer

no idea ?

obstbauer

mh, ok.. then there is still another problem why I don't see the value in iobroker

obstbauer

sensor appears but no values

obstbauer

do I need all files or only the "upd_values_device_page.js" file?

Because I can see the values now on the esp web interface but I don't see the values in iobroker
the other esp devices are sending the values to iobroker

obstbauer

it works, thank you
now I can see the values

obstbauer

ok, this is a 4 MB Lolin NodeMCU V3.
Would it be better to make a firmware update with the newest version ?
now it is ESP_Easy_mega_20230507_normal_ESP8266_4M1M May 7 2023

obstbauer

this post was from me too
with my ESP01 it works now

but here I have another problem, the web interface looks normal, the measurements shows right values but not on the page I showed

obstbauer

yes it worked

Thank you!

obstbauer

I uploaded "upd_values_device_page.js" but it doesn't work

obstbauer

ok I uploaded all files but it doesn't work

should I delete the "update_sensor_values_device_page.js" file ?
and upload the renamed file again ?

obstbauer

is it right what I wrote ?

obstbauer

you mean

"File browser Show files on internal flash file system"

and then upload the *.js files?

Thank you for the help!
