Hello, it is possible to send a http command from the bash shell. string stdout; string stderr; system.Exec("wget -O /dev/null -q http://<ip of your device>/?cmd=reboot",&stdout, &stderr); Another possibility is using php to send the command. a php command for this might be: file_g...

Shardan, any recommendations on an inexpensive oscilloscope which will work for these and not take up much space? Mostly I expect I would use it for looking at power on the ESPs and maybe some sensor communications. I try with ina219s but they are too slow for measuring mA the esp uses. I'm using a...

Shardan

Thanks Shardan, completely make a sense. Still thinking about distribution of power for sensors in ceiling through whole house with one reliable source of voltage. A central source has it's advantages and disatvantages. But we should discuss that in a new thread, it's getting somewhat off-topic her...

Shardan

Thanks

If i get such a power supply on my desk again i'll do some screenshots from the oscilloscope
and make an extra posting in the Wiki... might be helpfull.

I got adaptors that give anything from 4.7V to 5.4V. For ESP devices that are driven by 5 V a range from 4,7...5,4 V is completely OK - if there are real 4,7..5,4V!! They usually have a LM1117-3.3 or similiar voltage regulator that gets voltage down to 3,3V. They will work with 5,4 V as good as wit...

Shardan

what about connection? I don't think DHT22 and AM2320 are pin compatible... do you have any info about it ? Have a look at the datasheet: https://akizukidenshi.com/download/ds/aosong/AM2320.pdf On page 3 you'll find the pinout of the AM2320. On page 21 is a schematic for using it as a one-wire devi...

Strange.
Well i have to pass on that point.
With FHEM the issue was reproducable easily.
I've not hte slightest idea why it disappeared on your settings.

@krikk I see you started something on the wiki. I edited it a little bit. I think we can keep the table on the main wiki and link the devices there. I like the table, looks nice. I've added the Sonoff 4ch to the table meanwhile. When i learned how to make a page and a link i'll write a "HowTo ...

"addicted" is the word....

Welcome to the forum. Don't hesitate to ask, we will answer whereever possible.

Shardan

hmm... interesting (Spock would say "fascinating"..)

Did you re-download the dev8 or is it the same file as before?

Would be the easiest explanation.

Shardan.

I really have to support Costo's cause here. This is what the "typical" ESPeasy device looks like https://www.letscontrolit.com/forum/download/file.php?id=1169 https://www.letscontrolit.com/forum/download/file.php?id=1170 Maybe a solution could be to disable RxTx as well as I2C on SonoffP...

Shardan

Yes and no. Not everyone who can code knows about electrical security and vice versa. So such a locking looks a bit "Absurdistan" like to me. A coder without knowledge can work around within 10 minutes and a security trained guy without coding knowledge can not? Oh rly? The people using ES...

Hello, if you want accurate measurement i recommend to use a somewhat precise thermometer directly besides the sensor. I use something like this: http://www.alexmo-cosmetics.de/bilder/produkte/gross/Laborthermometer.jpg These lab thermometers are sold for around 5..6€ for a non gauged version. Why t...

Shardan

Hello costo, the "Amica" ones are somewhat reliable here too. As i buy them from China for a really low price it's acceptable to me if one out of ten is defunct. I bought two lots of five of the "LoLin" and sorted out half of them - that is definitely not acceptable. As i stored ...

Shardan

This will be a problem at every given time. The ESP gets warm and the voltage regulator on the WeMos D1 (or any similliar board like node MCU too) gets warm. As costo said you need to get some distance between the sensor and the WeMos. This can be done by pin headers or Dupont cables. Another possib...

Shardan

Hello toffel, how long is the delay for reporting? The memory leak occurred here every time the ESP reported to my FHEM server. If i disabled the "Send data" in the tasks it stopped leaking. So for testing we used delays of 1s and 5s bringing down the free ram very fast until the ESP first...

Hello Thomas easiest way is using rules. I've a sonoff basic in my office ceiling light and use a simple rule for that: On System#Boot do gpio,12,1 endon The advantage of that: I can switch light on with the standard wall switch in case of failure. The disadvantage: It takes about 6 seconds until th...

Shardan

Okay. I analyzed the failing connection with help from psy0rz and we found the memory rapidly decreasing when my FHEM controller is connected, a memory leak. Psy0rz was able to reproduce the bug and fixed it, That's what is compiled into the binary. So it would be nice if you check the free RAM now ...

Would be interesting indeed.

Thanks for testing.
Check the free RAM on the webside, it should not decrease over time.

Shardan

You're welcome

Shardan

I don't know the OTA from inside. It might be impossible to update. If i look at the size of the .bin file it's 532KB. As far as i know the .bin file is uploaded completely to the ESP before replacing the existing code. If so and there are no further "tricks" like file compression it will ...

Here you go. This is the version i used for bulk testing, it is running on nodeMCU and WeMos for around 2 days without issues. It is compiled with the "normal" option, so no testing or development parts are compiled in. firmware_normal4096.zip . Anyone who wants to use it: This is NOT an o...

If you want a reliable and cheap progger, chose one with a CP2102 or a CH340 / CH340G. Just to be clear. The progger I got and that I linked to is CP2102 based. Here's a filtered search. And it looks quite nice and nice price too. Might be a next one for me if i break my progging cables again :)

Shardan

I might be wrong, but I think the S20 has an ESP 8285 instead of a EPS 8266. I just opened one and checked: they use an ESP8266EX and an external BN25F08, which for the latter I could not find any datasheet or documentation. CherAlban The markings on these chips are somewhat tricky. In this case BN...

In comparison I would say: NodeMCU advantages - bigger 3.3 V power regulator with, enables you to drive many sensors/actuators without secondary power regulator - more 3.3V and GND pins allow for direct connection of sensors with dupont wires: great for prototyping - probably very good as your firs...

Hello again, updating from the R1xx to the 2.00 versions will delete all settings due to internal changes, thats correct. When flashing a 2.0.0 over a 2.0.0 the settings will stay as they did with the R1xx versions. It should not make much diofference if you compile on Arduino or PlatformIO. Did you...

It's not included in the actual bin files,
the fix was added later.
If you need a binary let me know.

can you give some details please? - is a controller (domoticz, FHEM, openHAB.....) connected? - Are sensor values reported to the controller? - Some special things configured?

Hello all, for testing a fix i've used several nodeMCU's. This lead to a bulk quality test of these boards as i run in several problems. I've used two different versions, the older one with CP2102 as USB-TTL converter (a white back label says "AMICA" for brand) and a newer version with a C...

Hello, to keep that clear: I'm not a developer of ESPEasy.

Perhaps we have to look in different direction than measuring impedance/resistance between 2 poles. An ESP8266 (and also Arduino and Raspberry) has capability as pulse-counter which could be applied as frequency-measuring, by counting incoming pulses per fixed interval.

The picture from krikk shows very impressively what DC current does.

It's easy to see that the left side is the "anode" size, loosing metal ions to the other side.

DC driven rain sensors are nice for experimenting. They are not made for permanent use.

The sensor i used has it's own voltage regulator from 5...15 Volts to 3,3V. i can't say what the small sensors use, i didn't test them yet. The PIR's with their own regulator will not work easily with 3,3V as the regulator needs some volts for itself to work. This so called "Drop Out Voltage&qu...

Shardan

I'm wondering why it is not working. I just have soldered a server room sensor prototype that includes a PIR sensor and tested it: . USIR-Sensor Frontside.jpg USIR-Sensor-Backside.jpg . It works quite nice without issues. The PIR runs on 5V, the output is directly connected to GPIO2. Regards Shardan

Shardan

Hello,

if you use the Standard Setup of the Arduino IDE the "Export compiled Binary" command
generates the .bin-Files in the source folder where the ESPEasy.ino-File resides.

Regards
Shardan.

Shardan

Hello Dylantje,

put a resistor of 10K-Ohm from +3,3V to the Data Out / GPIO-Pin you use for PIR.
