    Do you have battery relay pin set?

    I don't understand this. This is my pin setup.
    Screenshot showing pin configuration settings of an electronic device, with functions assigned to each pin.

    EDIT:
    I copied the pin settings from the Tuya PIR sensor, this had a battery relay pin.
    Now battery voltage measurement work as as expected.

    I am not an expert when it comes to battery driver, but you've posted this JSON in your previous post:
    Code: text Expand Select all Copy to clipboard
    
	"samp_sw_pin":"17",
	"max_V":"3000",
	"min_V":"2200",
	"samp_pin":"23",

    This means that sampling pin (ADC) is P23 and the sampling switch (Battery Relay) pin is P17.

    See the related battery driver article:

    Sending HTTP GET also allows you to control other devices (e.g. Tasmoty or OBK, via cm?cmnd=COMMAND), but I don`t know if it is needed, because OBK also supports the Tasmoty Device Groups protocol anyway:

    Could I ask for an example of how to set the sensor in OBK so that when it wakes up, it performs a GET request to an external HTTP server?

    All examples are here:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/autoexecExamples.md
    If sending data via HTTP GET, search for "SendGET" on the website, for example:

    Is it possible to reduce the waiting time for mqtt connection? Or should I disable it completely so that deepSleep follows the defined DSTime?

    Hello, from your description it looks like it uses the DoorSensor driver. DoorSensor assumes that the sensor is used with MQTT. However, then you write that you want to completely turn off waiting for MQTT... maybe it would be better to script the sensor "on foot" using the command PinDeepSleep ? I posted a similar example in the previous post, you just replace DeepSleep with PinDeepSleep to wake up with a button.

    @p.kaczmarek2 admits that it crossed my mind, although I wasn`t sure which command I should use to send him to sleep :)
    So in my case, the reed switch energizes the device and:
    Code: text Expand Select all Copy to clipboard
    waitFor WiFiState 4
SendGET http:/ip?doorState=$var1
delay_s 10 (poczekam na zamknięcie drzwi)
PinDeepSleep (żeby poszedł spać aż znowu obudzę go kontaktronem) 


    The question is how to extract the variable from the reed switch? In terms of whether the door is open or closed.
    How to extract state from BatteryADC to a variable? publishFloat "voltage" $CH1/1000 ?? (from your examples) always gives me 0
    How to code a trigger that will send SendGET when the sensor state changes during wake-up?

    This is not correct. We store variables in channels, for example:
    Code: text Expand Select all Copy to clipboard
    
SendGET http:/ip?doorState=$CH1

    Mad_Maxs wrote:

    The question is how to extract the variable from the reed switch?

    You set the pin with the sensor to the appropriate role (e.g. dInput - digital input, or its version with pull up) and assign it a channel, it will read the value 1 or 0 to this channel, and you will use $CH1 in the script (change the index accordingly) to read the channel.

    Even ADC is handled in the same way - you set the ADC pin, assign a channel to it, and the script has access to the values from the ADC. But that`s just incidentally, I`m giving an example.

    Search for "battery" in the list here:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/constants.md
    The above assumes that the battery controller is configured.

    Mad_Maxs wrote:

    This is a strange question. You currently have a script that is executed immediately after waking up, so in fact you have already created the trigger.

    I will just add a small tip - depending on what you want to achieve, it is worth considering the situation in which someone opens the door for one second and then closes it immediately.

    PS: You chose the challenge with this door sensor a bit difficult. This can be problematic, because if you create a script like "wait 1 second and sleep", you will block the possibility of saving the sensor without UART. I recommend caution. Maybe it would be worth practicing with longer delays to get to know the environment and not make any mistakes in the script due to ignorance.

    Added after 46 [seconds]:

    You can try it yourself and maybe tomorrow I will write (but without testing) a sketch/example of autoexec for what you want to achieve

    Now I think so, maybe this question is about what if someone opens and closes the door before the WiFi is connected?
    If so, script writing the sensor value to another channel at startup and publish both values via HTTP after connecting to WiFi.
    Something like:
    Code: text Expand Select all Copy to clipboard
    
// save door state at boot time - it assumes that channel 5 is a temporary variable, and channel 1 is door sensor
setChannel 5 $CH1
// wait for WiFi
waitFor WiFistate 4
// send both states
SendGET http:/ip?doorState=$CH5
delay_s 2
SendGET http:/ip?doorState=$CH1

    @p.kaczmarek2 so putting everything together, I get:
    Code: text Expand Select all Copy to clipboard
    
setChannel 5 $CH0
waitFor WiFiState 4
SendGET http://IP/sensor.php?doorSensor=1&sensor=$CH5&bat=$batteryLevel
delay_s 2
SendGET http://IP/sensor.php?doorSensor=1&sensor=$CH0&bat=$batteryLevel
delay_s 2
PinDeepSleep

    Unfortunately, there is always a chance that someone will shoot perfectly at the moment when the sensor falls asleep, although tests show that you must be lucky. This delay_2 before PinDeepSleep is important. Without it, it was impossible to send the second GET

    I saw it with the channels, but somehow I convinced myself that it should be a value, e.g. $CH00 instead of $CH0.
    Sometimes it`s hard to get off such a wrong path on your own.
    I already made Delay_s 1 by adding DeepSleep 120 to autoexec.bat :) apparently a person once programmed ESP8266, where the command was similar, but when I made the connection, it was too late. An additional question arises: how to remove such a whip from the programmer level? Because I uploaded the firmware again, but the configuration was saved ;) only when I uploaded ori and it went obk

    Added after 6 [minutes]:

    I think that it would be worth adding an if here that will check whether $ch5 == $ch0, and if so, it will not send a second SendGET

    I would suggest scripting better in bat so that an additional button (e.g. with a Btn_ScriptOnly pin, or even as DigitalInput) checks whether it is pressed and if it is pressed, exits the script.
    Maybe something like:
    Code: text Expand Select all Copy to clipboard
    
// script assumes there is a digitalInput on channel 2, which is low by default and high if user presses the button
if $CH2==1 then goto nothing
// here remaining script 
(...)
// at the end of everything:
nothing:

    The above code will make it so that when the configuration button is pressed, "goto" will skip the rest of the script and leave the device turned on permanently (until the user reboots)

    So, summing up all the additional changes, we get:

setChannel 5 $CH0
waitFor WiFiState 4
SendGET http://ip/sensor.php?doorSensor=1&sensor=$CH5&bat=$batteryLevel

if $CH5!=$CH0 then SendGET http://ip/sensor.php?doorSensor=1&sensor=$CH0&bat=$batteryLevel; delay_s 2
if $CH1==1 then goto nothing
PinDeepSleep

nothing:

    I added this IF with a comparison of channels 5 and 0, just check if I wrote down the execution of two commands correctly (separated by a semicolon), are any additional brackets necessary?

    If I replaced PinDeepSleep with the DeepSleep 43 200 command, is wake-up from the pin still available, but I have a control signal every 12 hours? in ESP, excitation from the pin was independent of the code, but I want to make sure :)

    This won`t work. At the beginning with @btsimonh we decided to follow the basic Tasmota syntax, so if you want to enter several commands with a semicolon you have to use backlog . backlog something; something; something

    You could divide these delay_s 5 into 5 delay_s 1 (with a loop or manually) and check this safe mode pin every second

    Currently, DeepSleep will not be woken up from the pin because there was no such option in the SDK. Only recently a PR for the SDK appeared:
    https://github.com/openshwprojects/OpenBK7231N/pull/18
    And only in the future will I integrate it, then it will work as you write.

    You`re right, but in its current form, you`d have to wait those few seconds while keeping it pressed. Alternatively, in nothing, you could blink the WiFi LED 3 times as confirmation of exiting the script to be sure that it is finished.

    Bright:
    Close-up of an electronic module with connected wires and a battery compartment.

    However, I have a strange problem: I loaded the pinout into it:
    Code: JSON
    Log in, to see the code

    I have a reading of the battery status, on channel 0 I see a change when the magnet changes position, and yet after switching to PinDeepSleep mode, the change in the magnet position does not wake him up

    //EDIT
    I found that the btn is pin 14, now when it sleeps, I can wake it up with the button, but it still doesn`t respond to the magnet.

    By the way, how can you calibrate the battery reading, because it`s a bit off with the meter ;)

    Doesn`t changing the position of the magnet wake up the equipment only when, for example, "opening the door" or only when "closing" it, or does it not wake up at all?

    You must correctly select the pin role, i.e. DoorSnsrWSleep without pull up/down or DoorSnsrWSleep with pull up or pull down.
    Additionally, you also need to choose one of the three DSEdge options.

    It does the job, although btn works more like a switch. By default, $CH2 is 0, I press (and release) and the state changes to 1, I press and release again and the state returns to 0. Is it supposed to be like that? Because this is another device that reacts this way to the use of BTN

    Congratulations, you found an edge case in the if that was handled incorrectly by the parser. I posted an update, can you first disable deep sleep and then do an OTA to the version that will appear on Github in about 10 minutes (when it compiles)?

    EDIT: yes, an alias can help, but I also posted a fix for it on the repo so this problem won`t happen again, the automatic testing system will take care of it:

    Hi,

    I have successfully flashed the device and everything appears to be operating as expected. However, altering the DSTime setting does not result in any change. The countdown always starts from 60, regardless of the setting. I've attempted to modify this in the startup code and tried initiating the Driver beforehand, but to no avail. Does anyone know how to change the DSTime setting or is it a bug?

    Thanks!

Topic summary

The discussion focuses on configuring a door/window sensor using OpenBeken without TuyaMCU, emphasizing deep sleep functionality for energy efficiency. The sensor connects to WiFi only to send state changes to an MQTT server, minimizing power consumption. Users inquire about HTTP event notifications, firmware updates, and the impact of static IP on battery life. Various responses address configuration issues, connection times, and the importance of using the correct firmware version. The conversation also covers the calibration of battery readings, the implementation of GET requests upon waking, and troubleshooting connection delays. Key solutions include using the DSEdge command for wake-up configuration and ensuring proper pin assignments for functionality.
