Hello,

I found a very easy solution for my problem. I had do mark in the setting from the MQTT adapter the function "Send states also". Now I could see all datapionts I want on my display.

Best regards

Hello, I tried to realise it, it didn´t work. I changed the topics from row 1 to 2 and from row 2 to 1. and the values I could see in the overview will also change. But, all values I want to show, appears but will not be updated. Now I startet a MQTT Explorer and I could see, that the values I want ...

bastler11

I tried to take other objects.I took it from my photovoltaic system. First the value of the total energy is not correct, instead of 4548Wh it shows only 2814Wh, and the value didn't change. Also when I try to write under formula %value%*2 nothing happens? It will be shown 2814. Did I make any thing ...

bastler11

Where does the value 476 come from? Also when I create a new Generic - MQTT Import, it shows 476.It seems that after the first reading the value is fix stored? Reboot the ESP didn't help.

bastler11

One more thing, the value I could see will not be updated? It shows only 476.00W? To start the ESP new didn't help.

bastler11

Thanks, I added the prefix, but no change. But after typing slash before the topics it worked.

As you write I had to add "W" vor the value.

Thanks all for your help and patience

bastler11

Hello Ath, I tried to realise it, but it does not works? All values are shown with 0, but that is not correct. The values currentPower is 450W.
So could you tell me were is my mistake?

Here some screenshots: objects in ioBroker, MQTT import, devices overview, setting

Hello TD-er, I´m not able to realise it. My first step to find out how to work with the display, I tried to show the temperature of the connected DS18B20 temperature sensor. It worked with [Name#Temp]. But how could I take the value of the currentFeedIn which I have in the objects of my ioBroker? Th...

bastler11

Thanks, I will try to use it.

Hello, I want to present the actual excess energy datapoint from my iobroker on a display. So I prepared an ESP8266 with ESPEasy and connected an OLED display. This work fine now (thanks to Ath). But how could I read any data from the iobroker? If I want to send from the ESP8266 any data to iobroker...

bastler11

Very good idea! It works with 3,3V

Thanks

bastler11

Hello, I tried to connect a SSD1306 display to a ESP8266. I found the display after scanning the bus. The display is new but it shows nothing. Do I make any mistake? I connected the display 5V -> Vin ESP, GND -> GND ESP, SCL -> D1, SDA -> D2. Here are also two screenshots from ESPEasy. Does anybody ...

Hello,

I bought an ESP32-CAM. It works fine. I use the program in the Arduino IDE. Is there a possibility to use the cam with ESP Easy?

Thanks and best regards!

bastler11

Thanks, it looks good. I will try to do it.

bastler11

Thanks, but how could I do it? There is the %value% in the las row, and how could I get the value for example after 1s, after 2s, 3s, ...? If I have these values I write: 1.%value% + 2.%value%, ....10%value%/10 =mean? Hope you understand it?

bastler11

Hello,

on my ESP 8266 with ESPEasy I measure an analog signal 0-5V. This signal is connected on Ain0 at ADS1115 ADC.The output signal which is shown under device sways about from 4570 - 4670. Is it possible to calculate the mean in ESPEasy? How could I do it?

Thanks for your help!

bastler11

Hello Markus,

did you solve your problem? I'm wondering, there is a difference between the sensor in the device list HS-SR04 to your sensor JSN-SR04T? Did you also note that the output signal of the sensor is 5V and you have to reduce it to 3,3V?

Regards

Ingo

bastler11

Thanks and best regards! It seems it works

bastler11

It is the firmware which come with delivery, no ESPEasy. A copy of that firmware I do not have. So I must try to copy the firmware from the board. I didn´t made this before. You have some hints how to do it?

Thanks and best regards!

bastler11

Thanks,

if the charging controller does not work, how could I go back to the "normal firmware" which is now on the board?

Best regards!

bastler11

Hello I want to flash my WeMos D1 Esp-Wroom-02 ESP8266 WiFi Nodemcu Module with battery. Could you help me to find out the right firmware?

Thanks and best regards

Thanks for this information! I had just a look on it. Several parts I could understand bus several not :roll: If I could wish for something: A story with text and pictures described on a specific task 1.

bastler11

wow, thank you very much! You are right, I'm in the moment not able to build the image, but I think I have to learn it

. I will test your image!

Best regards!

bastler11

Hello,

I want to use the scd30 together with an esp8266. Which actual image could I use?

Thanks and best regards.

bastler11

Hello,

is it possible to download the prepared espeasy image for esp8266 ?

Thanks and best regards.

@HomeJCL

It is right, the output signal is 0,5V with atmospheric pressure.

I tried to get a data sheet from the sensor, I got no information from the seller. Does anyone has mor technical information about the sensor?

bastler11

The sensor could be set 20cm in the whole. The temperature difference I think is not so big. To check how big is the difference I could take a DS18B20. But I think 80cm in the earth the temperature will stay constant. So only the area between -80cm to -20cm will change the temperature and may be inf...

bastler11

I want to connect the sensor with a cat 6 cable and fix the esp is in the greenhouse. May be there are two other possibilities: 1. I put the esp in a water resistant box directly near the sensor and take the 5V from the greenhouse? 2. I take an adc directly near the sensor in a small water resistant...

bastler11

Hello, I got the sensor and made the first test, here are some pictures. First I had to build an adapter between the copper pipe and the sensor. Then I assembled all. The copper pipe is 4,25m. The actual water level is 2,45m. The copper pipe should stay 1,8m in the water and the sensor output I got ...

bastler11

Thanks, I will try it. Hope Amazon delivers soon

.

bastler11

Ok, I don't know how the pressure sensor is build inside, it was only an idea from me. I will check it when I get the sensor.
The 100nF I place direkt near the ESP and the bigger capacity? Also there or better near the sensor?

bastler11

Yes, you are right. But this I do not understand: I guess it is better to add one resistor in series with the resistor part of the potentiometer to make sure the max. voltage on the middle pin can get as high as your analog input may accept. I think I have to choose a load resistance witch is 10x Ni...

bastler11

Here is the circuit. I don't know the resistance from the pressure sensor, but I think I could take the voltage divider 1:5 or 1:10. Than I'm sure that the voltage at the ESP ADC is max. 1V.

bastler11

Sure, I will write down my experience here

. Yesterday I ordered an additional pressure sensor. So I will have two options, pressure and the laser distance sensor.

In my example circuit from 23.04. I think I made a mistake. I made a new circuit. And I have to check that the max voltage is 1V.

bastler11

Yes, but than is there still the problem with linearity. Would the possibility to hang the sensor in the the well pipe at 4m not better? I only have to look that the connection to the short cable of the sensor is waterproof.

bastler11

@ TD-er Yes that's right. Either I try to calibrate the system bevor outside with a similar pipe of water or I put the sensor down in the water. Than the pressure is linear with falling or rising water level. So the 0-30 psi sensor should be ok. @Ath When I press out the water in the pipe I think th...

bastler11

Ok, but I do not measure the pressure in the water, I measure the pressure of the air in the pipe when the water level is changing. I take the sensor pipe in the well pipe and than I press the water with air out. That is than the zero point. If the water is going up the pressure of the air is rising...

bastler11

I think with this angeld auto hose valve it would be possible to press out the water in the pipe. But I'm not sure about the pressure measuring range.

bastler11

I found the pressure sensor at Amazon. It works for example from 0-30psi. Normal air pressure is about 15psi. If the small pipe with the sensor is 4m long and the level difference is about 2m the pressure difference is about 15psi. So it should work? Or is it better to take the 0-80psi sensor?

bastler11

Do you have also the type of the sensor in the picture ? The BMP280 is only on a circuit board available, because of the high humidity in the pipe is not so good? What would be interesting is the temperature at about 80cm under the earth. It is the deep of our pipe from the toilet water cisterne to ...

bastler11

Good ideas! To use the pressure sensor seems better, because of the high humidity in the well pipe. So what I can do, I take the pressure sensor (which type is it?) and fix it at the end of a small pipe (see the picture). I do not know what is the lowest level. I checked now that there is a differen...

bastler11

Update is ready, so I have to wait for delivery

bastler11

@Ath

I have this build on my esp 8266 ESP_Easy_mega_20210223_normal_ESP8266_4M1M. So I have to update it?

bastler11

I hope I will get soon the sensor to try it out

.
Because of the not exactly vertical pipe, I hope that it will work if I position the sensor about 50cm above the highest water level.

We had connected a pump to the well pipe until last year. Since the built-in filter was not fine enough and there was a lot of sand in the water, I drilled a new well and installed a special filter against very fine sand. In the old pipe I wanted to constantly log the groundwater level to see how it...

bastler11

The idea with the cable as a capacitor is good. I think if I take a cable from for example with 9m I can double the cable so that the two ends are on top. Than I have 4 plates and no isolation problem in the water. To test it, I think I could take a similar 2m pipe which I fill with water. But how c...

bastler11

The pipe is made from PE, but it is in the earth. I only could only make any thing inside.

Hello everyone, I would like to ask you for advice on how to solve the following problem: I would like to log the water level in a well pipe. Unfortunately, the pipe is not completely vertical, but rather curved. Therefore I cannot see the water level directly from above. The tube has a diameter of ...

Hello to the community, first of all I want to say thank you very much for this very interesting forum! I want to use some ESP boards in my ioBroker system.
