Tasmota: Can I support the reed sensor?

[ChienTing]

Can I support the reed sensor?
In the door mounted on the reed sensor
Open the door relay on
Close the door relay off
Thanks

[smadds]

It's just a switch, @ChienTing, so wire it up like a button. MQTT will fire an update to any subscribers when the state changes, so you can use Node-Red or a home automation package to work out the logic

[off14]

if i wire it to GPIO14, how to tell sonoff that it is not for relay control?
so that relay control stays from WIFI or internal button (gpio0).

[davidelang]

define it as a switch and set switchtopic
k

[off14]

tks!
can it be done via user_config.h, or only after in console?

[davidelang]

I think only via commands (console, mqtt, etc)

[off14]

great - after playing with SwitchMode and SwitchTopic, sonoff now works as two independent devices:

1. switch (pulse switch in my case), can be toggled via wifi or via internal button
2. door sensor - when change status sends ON/OFF to a specified topic. works when gpio14 connected/disconneted to GND via reed sensor

[TRIROG]

@off14
Would you mind sharing your configuration - what commands did you use?
I'd like to achieve the exact same thing.

EDIT:
I think i have it.
I set GPIO14 to Switch2
Then via serial i defined SwitchMode2 1
And also via serial i set SwitchTopic to 1

However i can't seem to understand What is the difference between Switch and Button in module configuration? What is the purpose of ButtonTopic command?

[off14]

1. you have to to to WEB configuration/configure module and configure GPIO14 as switch1
2. go to console on web
   2a. type: switchmode 2
   2b. type: switchtopic alarm
3. DONE.

now, relay is INDEPENDENT from the gpio14.
you can still toggle relay using MQTT (or web). and if door is opened(or closed) you will receive "cmnd/alarm/POWER" message (ON or OFF).
you can toggle the relay using original topic e.g. "/cmnd/sonoff/POWER" but reedswitch becomes independent.

@off14 What Sonoff module and reed switch did you use for this setup?

[sabs01]

thanks off14 - this has been very useful - any idea how to set up GPIO3 or GPIO1 to accept a second and third reed switch like this???

[stale[bot]]

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[stale[bot]]

This issue will be auto-closed because there hasn't been any activity for a few months. Feel free to open a new one if you still experience this problem.

Hey guys, I have made all the changes as @off14 described but still can't get the state to update automatically in HA.

Reed is independent of the switch and it does update state if moved manually.
But I want to able to update state based on time interval or state update mqtt msg.
Reason being, state always defaults to unknown if mqtt server loses connection or HA restarts

I've tried all these three sensors in HA without any luck

  - platform: mqtt
    name: "Alarm"
    state_topic: "tele/alarm/SENSOR"
    value_template: "{{ value_json['Switch1'] }}"
    unit_of_measurement: "ON/OFF"
  - platform: mqtt
    name: "Alarm2"
    state_topic: "cmnd/alarm/POWER1"
    value_template: "{{ value_json['Switch1'] }}"
    unit_of_measurement: "ON/OFF"
  - platform: mqtt
    name: "Alarm3"
    state_topic: "tele/garage/SENSOR"
    value_template: "{{ value_json['Switch1'] }}"
    unit_of_measurement: "ON/OFF"

And here is my config.yaml setup

```cover:

• platform: mqtt
  name: "Garage"
  state_topic: "cmnd/alarm/POWER1"
  command_topic: "cmnd/garage/POWER"
  payload_open: "ON"
  payload_close: "ON"
  payload_stop: "ON"
  state_open: "ON"
  state_closed: "OFF"
  optomistic: false
  retain: false
  cover.garage:
  device_class: garage
  friendly_name: "Garage"
  ```

Hello,
I try to make an independent sensor and I follow the steps but I do not get results.
1 you have to to to WEB configuration/configure module and configure GPIO14 as switch1
go to console on web
2a. type: switchmode 2
2b. type: switchtopic alarm
DONE.

But not work, my sensor can activate relay and don´t have information on console about my sensor.

[RuneKyndal]

Im trying to do a similar thing. But on the sonoff seperately.

My garage door only have an open/close button. I want to know and control the state. Up or down. Not just "toggle"

Im adding a reed sw to be closed when door is closed

Relay and sensor on gpios. 14,RX

Want to do some logic in rules, switch and backlog
But it seams lacking in logic options.

(Human readable code)
Mqtt Cmd OPEN. "If sw1 closed"; Then POWER2 ON; delay 5; POWER2 OFF;
else do nothing
Mqtt Cmd CLOSE. "If sw1 open"; Then POWER2 ON; delay 5; POWER2 OFF;
else do nothing

With sw1 also being sent via tele. For visualizing the state.

Havent quite grasped the on, do, endon switch type logic yet

Although there are some examples of swiyching logic. Its not working for me yet.
Suggestions on how to do the logic part, independent on the sonoff?

"I´m solve my problem with mqtt, now work fine with my pir sensor (independient of Relay)"
Configure Gpio 14 Switch 3 and GPIO RX -->Relay 3. (This pin on the air, no need relay)
and type in web console:
switchmode3 1
SerialLog 0
Now PIR information sended to mqtt and can configure in my homeassistant.
I make a spanish manual in domology.es but I´m not sure if can put here external URL.

[RuneKyndal]

Id like to come up with a solution, independant of the mqtt server though

[ffontanac]

An old post, anyway very close to what I'm looking for.

I have it correctly working (switchmode, switchtopic... etc), except in case the sonoff reboots and the sensor is triggered, it doesn't boot. I think it reacts as if the button1 would be long-pressed during the boot.

Did someone experienced the same?

Solved!,

I'm using a R2 V1 sonoff (the new one) that doesn´t have visible GPIO14. Insted of GPIO14 I was using GPIO2 that cannot be low at boot (it doesn't boot when triggered).

Using GPIO03 (Rx) insted is fine.

Don't know why they remove the GPIO14 connector from the PCB!
