Thanks for the answer. The problem of cable length in my case does not occur because everything is in one small housing. But I reduced the clock to 100kHz anyway. As for the FW of the sensors themselves, it is of course difficult to say anything. It's been working fine for 2 days now. What will happ...

The last time I made a new device based on ESP was over a year ago. Now I would like to make a new one consisting of 5 devices controlled by I2C. I have a question for colleagues about their experience with the stability of I2C operation over a longer period of time with FW versions newer than ESPEa...

OK, solved. I can query ESP from server using syntax like this:

Code: Select all

wget -O - http://192.168.0.28/json 2>/dev/null|grep '"SSID":"'

So is easy to retrieve SSID name from returned string.
THX for help.

mackowiakp

Is it possible to obtain content of text system variable like %ssid% from ESP to server by any HTTP server call?

mackowiakp

Both in the case of DTH mounted in the basement and sensors mounted outdoor, they are mounted outside the housing with ESP. So the temperature of ESP has no influence on them. There is intense airflow in the basement for the reasons I wrote earlier. The sensor installed outside is - also as I wrote ...

A humidity sensor measures the relative (!!!) humidity. The amount of water in air highly depends on the temperature. Higher temperature => air can hold more water. Thus: if you heat up air with some relative (!!!) humidity value of X percent, the relative humidity will drop since the capacity to h...

mackowiakp

Will, try. But potential problem could be influence of higher temperature to humidity readouts.

mackowiakp

OK, THX

mackowiakp

As for the temperature shift, I actually have no problem. I use DS18b20 for temperature measurement. It is hermetic and can be placed somewhere next to the BMExxx. I only use BMExxx for humidity measurement, ignoring other data from it. I even have a second sensor inside the winter garden to read th...

The photo shows a galvanic isolator for USB 2.0 devices. Up to 5 kV security.
An interesting fact is that it isolates not only TX/RX signals but also the supply voltage.
Has anyone seen a similar device for the I2C bus?

I come back to the old topic of the humidity sensor installed outside the house. The problem is that I live in an area with very high humidity. 80-90% is "normal" and in the morning it is also 100%. There is no problem with temperature measurement, but with humidity. I used DTH22, BME280, ...

mackowiakp

THX for the precise (as always) explanation !

I am only asking for confirmation or deny that I am thinking right. If I have selected in Menu -> Tools -> Advanced -> Restart WiFi Lost Conn: and I am connected to the AP, then with the "WifiDisconnect" command, the WiFi stack is reloaded and its reinitialization. Of course, depending on ...

mackowiakp

OK, thanks for the advice. I moved the topic to another forum because it is not a topic about ESP Easy itself.

mackowiakp

Sure, I see no reason why you couldn't set the IP of your router, SAT receiver or whatever Linux/Unix/Windows box which runs a NTP service on the default UDP port. Yes, of course. But I want to configure "pool" NTP. For example the name "pool.ntp.org" is not one particular serve...

I can not enter in config menu, IP address of secondary DNS server. I use many ESP`s with various FW release. So what is the proper syntax of DNS field in config menu to enter both primary and secondary DNS? The second question is not stricte ESP related. In ESP menu it is possible to enter only one...

What are the experiences of the Dear Colleagues from the forum? What is the max cable length for DS18b20 and AM2301? For SOnnOff, extension cords as long as 5 m are available (on Ali for example). Something does not bother me that ESP is working properly then. I am thinking of using a shielded headp...

mackowiakp

Gee ... I'm sorry, TD-er. My mistake. Again, I have the ESPEasy source files on another drive connected to Platformio via a symbolic link.
Well, I just did not give the appropriate UID/GID for the directory.
I should think first and then write.
I promise to improve for the future!

mackowiakp

OK, I downloaded the ESPEasy-mega-20220809.zip file, unpacked it to a directory and tried to compile. Previously - I don't know why - not everything was downloaded. Currently showing the following errors (copy/paste to G translator): error: The server does not allow a request for an unannounced obje...

mackowiakp

Will check when be back home evening.

mackowiakp

Release mega-20220809. I know there have been a lot of changes to the general directives for Platformio but I have a problem that FW won't compile. Below are the error messages: Processing custom_ESP8266_4M1M (platform: espressif8266@2.6.3; board: esp8266_4M1M_board; framework: arduino) ------------...

But Linux is like wigwam. No Windows, no Gates but Apache inside

mackowiakp

@ ThomasB
Yes you are right. But I don't want to test the new FW on a 24/7 working device (bit necessary).
And I do not have a free ESP32 at the moment, because I noticed this error message on such a platform.
I will order on Shopee, but the delivery will probably take a month.

mackowiakp

Thanks a lot for the clarification. The error message itself does not bother me because - as I wrote - the command is carried out. So I will not replace the FW with a newer one because - as the old rule says - "it works properly - do not change". But as soon as a new release comes out, I'l...

I want to send a SendTo HTTP command from one ESP to another.
The command on the second ESP is executed but the error message is signaled as in the attached screenshot.
Am I making a syntax error?
I note that the command is still carried out.

What I do find strange is that you could not get the unit to boot into flash mode.

Yes, its strange.
But I am happy to unbrick my unit at this moment

mackowiakp

I didn't know that after a 10 reboot the plugin was disabled. I waited those 10 reboots and it started working.
I mean, I have established communication with the device.
I've made corrections and so far it's OK.
Thanks to you TD-er! You always offer good advice!

mackowiakp

The sensor is connected...

mackowiakp

Terminal logs stands that it is FW CRC problem. So - probably - FW is couupted.
It is easy to restore FW, config etc. But it is impossible to flash it.

Test unit with only AM2301 sensor connected, works properly with the same FW.

I was 3 times in Ukraine so I have not time to test FW. Will do it ASAP.

mackowiakp

Well. I will replace the plastic cap with an aluminum one and the sensor itself. We'll see what happens in a few months.

Does anyone have an idea how to protect the BMP680 sensor outside? After about 9 months of operation, the BMP680 still correctly displays temperature and humidity, but the pressure and AQI readings are completely random (e.g. AQI = 1200). Currently, the sensor is installed in a "housing" m...

At the moment, MPU6050 motion detection works in such a way that the statement that motion has occurred is based on the finding that activation has occurred in ALL enabled axes. In the case of a washing machine, it turns out that it is better to check that the stimulation occurred in ANY axis. I wro...

Reducing the I2C clock frequency to 10kHz seems to have solved the problem. And the source of the problem was probably a long cable (1m), which is the limit for the frequency of 100 kHz, and the induced noise in this cable, generated e.g. by the washing machine's motor. I still have to test it. But ...

All this drives me to assumption that there is something wrong with my copy of MPU6050. The problem is that I am waiting for a new delivery from another supplier. I put the currently used sensor together with pull-up resistors, capacitor and soldered cables to the plastic bottle cap and filled it co...

mackowiakp

OK. But I think that lowering clock to 10 kHz help to resolve cable length potential issue and timings.
Can you point me a link to Your 4.4 SDK based build?
