hi, I am trying to get upyeasy on a esp32. after installing python, first hurdler taken, I had to install pyserial and finally got it done, but it took me some time to get there. next hurdle: I want to start Firmware install on esp32 by: esptool.py --port COM4 write_flash --baud 460800 --compress 0x...

Hi Thx for the input! I think i have found my approach. I will use an esp32 in order to have sufficient cpu power as well as gpios and adcs for at least 4 cells in parallel. Maybe i use an ADC wit i2c as well es i2c gpio. Esp32 will be used to switch mosfets and measure voltage and current on a 5 or...

karl222

Many thanks for the explanation!!! It is not even the fact that i am having a spreaded infrastructure. I want to use many adc‘s and gpio‘s as well as pwm for a battery testing station for several batteries in parallel and i am running out of tasks, especially when using esp32 but also with esp. Ther...

Hi guays, I really llok forward to using upyeasy but haven‘t had a chance to try it yet. Are there more than 12 tasks available in standard upyeasy, as this would make things more easy for me doing more complex projects... Especially when thinking of more powerfull hardware like the esp32. I have ch...

No idea guys?

Great, thx!

Unfortunately i am not running a linux system...

karl222

hey guys, many thanks for your great efforts bringing espeasy to the next Level!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! As I am not a pro on all that stuff I would appreciate having a FlashESPxxx tool as with ESP Mega in order to install upyeasy... Maybe you did already and I am just too dumb to have it seen...

Hi there, I would like to realize a Charge/Discharge module for Li-Ion batteries with ESPEASY which can control a bunch of batteries at one time. Setup as follows: 1. activate TP4056 with relay or mosfet in order to Charge 18650 battery 2. readout led "fully charged" with esp using a MCP23...

karl222

ok. will set it up like this...

karl222

Thx
Nano easy seems to be on R148, though not really up to date...
Esp32: I didnt know that development is progressing so well. Seems promising!

Karl

karl222

You are right, probably the better way...

Thx

karl222

I would be happy to drive a mosfet for powering up the esp... e.g. a bs170 but don’t know how to...

Hi, in my house i am using Merten Argus Basic smoke detectors, which I want to become smart. They look good and Pollin has them for EUR 15,-/per 3 PCs. I bought them for 18,- each some years ago :cry: I have found out, that they use an IC called A5366CLWT. datasheet is here https://www.digikey.at/pr...

karl222

Nearly any small N-FET should work (BS270, BSS138, 2N7000, 2N7002.....) Just one point: These FETs are somewhat sensitive to electrostatic discharge. So a serial resistor between gate and sensor and a small ceramic capacitor 10nF .. 47nF between gate and ground gives at least some protection agains...

karl222

I'd like to challenge another approach. why not use the bs170 to power up the esp. this saves standby power at all. bs170 doesn't consume any power at all, when there is no water detected, only in case of high water gain of bs170 is errected and esp is powered up and sends a message on boot. I have ...

karl222

It was a hint from an other user. I think a standard transistor needs a higher current but maybe it works with a BC237 as well...

with the BS270 it works, I can confirm

karl222

Hi, I just did a fritzing for you. As a casing I ordered a few of these and will take out electronics in order to replace it with esp: https://www.ebay.de/itm/Wireless-Buzz-Warning-Water-Sensor-Alarm-Home-Security-Water-Leak-Detector-QP0/192217728047?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p205787...

Hi,

I have just tried a solution where I start the ESP out of deep sleep by giving a GND Signal to RST via a BS170 MOSFET Transistor. the current on the gate of the BS270 which is led through water is sufficient to errect the BS170...

karl

karl222

as I don't want to wake up the esp via delay I thought it is not necessary to wire GPIO16 to RST... and tataaaa, it works

by the way web log Level is already set to 2 by default...

thanks
karl

Hi there, I am experiencing issues with deep sleep again. Yesterday I was trying to build a water leak sensor where the esp should be started via signal on RST pin. But it doesn‘t go into deep sleep, just once and I couldn‘t get it happen twice. I have googled a lot and I am not sure what the right ...

karl222

you say "Circuit, witch switch on power for ESPEasy when water leak is detected, its not big problem. "

how are you going to solve it?

karl222

Hi
Thanks for inputs...

Concerning NAND, you mean I should connect both NAND inputs and use it as one electrode and put + on another electrode. In case of water shortcutting electrode NAND goes on high...

Right?

What would i have to set as parameters in espeasy?

Karl

karl222

hi there, has anyone built a water leak sensor with the esp? I would like to put it next to our washing machine on a battery powered Basis which sends a message to my homeautomation system... From my point of view there are two Options: 1. having esp in deep sleep and waking it up via interupt comin...

karl222

hey guys, After digging a bit deeper I found the solution. the sensor itself has i2c but the breakout module delivers analog signal which can be processed by an ADC. this is fine! Curious, I only get values between 10 and 30 on an esp ADC, which translates to 0,01 to 0,03V with 1024 Digits (10bit) a...

karl222

thanks for help. i didn't know the wiki on that - very helpful!

karl222

hi there, does anyone have an idea how to integrate this VOC sensor. it has an i2c interface. it seems obvious that it needs some re-coding but in general should be doable due to i2c interface. her is the datasheet https://cdn-shop.adafruit.com/product-files/3199/MiCS-5524.pdf it sells for just USD ...

karl222

hi there, I want to make my smoke detector smart by attaching an esp to it. there is a trigger output on the smoke detector which goes to high on alarm. with it I will power up the esp - this means no deep sleep setup and absolutely no power consumption during standby. what do I have to add to rules...

karl222

That looks really promising but unfortunately it does not look very mature. In general i would prefere smaller hardware...

But anyway, thanks for the hint!

karl222

Hi
I am looking for a device like esp with programming like espeasy but it should support ethernet...

Does someone have an idea?

Regards
Karl

karl222

I don‘t know how but i finally got it to work!

Thx to all that tried to help

Karl

karl222

as it is quite cheap, i will go for a new one. i also have a 2.4" one and this one works fine...

many thanks
karl

karl222

interesting!
please keep me updated

with my solution I am running the sensor 6-8 weeks on one full 18650 cell... this is ok for me now.

hi, I am using mega 2.0 V12 and I have connected GPIO16 and RST in order to have deep sleep available. When I check deep sleep in the frontend with 120s delay, it doesn't work. Same issue with V11... are there any known issues with espeasy? can I check somehow, whether the esp accepts the new settin...

karl222

I have tried a ssd1309 now with ssd1306 settings and surprise, surprise 1309 is identified and works very well! I will try to figure out why the ssd1306 doesn´t work the 1306 display shows VDD and the 1309 shows VCC. VCC works well with 5V, maybe I've killed the 1306 by applying 5V. The datasheet fo...

karl222

hi there, I have done several things with esp and espeasy so far and I am very happy with results. Today I have tried to get a SSD 1306 OLED up and running but I was not successfull. In general it is easy to connect SDA and SCL and + / - Then I did a i2c scan but nothing happens.. also tried to chan...

karl222

Hi,

many thanks for your input. the smartest way to get a long battery duration is to use a sensor with low current like the BME 280. I am going to use this one.

best regards
karl

karl222

Of course i can switch it off via relay. Thanks for the transistor solution! How should parameters for espeasy should look like? How can i configure espeasy in order to activate a gpio for lets say 15 sec.or for uptime of esp... By the way, i am using that kind of battery shield, which works very we...

karl222

Hi all,

Has anyone developed a solution to run a esp8266 with espeasy and an i2c sensor, where the sensor is switched of, when esp is in deep sleep. When sensor is not turned off, it will empty the battery.

Any ideas or plans ho to realize that.

Best regards
Karl
