Tasmota: Sonoff Basic with external button and single press/double press/hold

[twieland]

Hi,

I've been trying for some time now, but I'm not sure how to achieve what I want (or if it's actually possible). I have a Sonoff Basic with an external push button and here's what I want to do:

for single push: change the local relay state
for double push: send some command via MQTT (-> want to switch another device on/off)
for HOLD: send another command (or the same with HOLD message) via MQTT (-> want to switch a THIRD device on/off)

I've been trying all kinds of different options but didn't succeed so far. Is it even possible?

Thanks!

That works for the internal button now as expected! What do I have to set for switchmode/switchtopic to make it work for the external button? It's connected to GPIO14 and set to "09 Switch 1"

[ascillato]

The external button is a pushbutton or a key (like the wall key to turn on/off a light)?

[twieland]

A pushbutton, i.e. the same kind as the internal button on the basic

[ascillato]

The HOLD feature is only available if you set your pushbutton as button in the module configuration.

[twieland]

ah, ok. I can only set it to Button2 then, right? how can I configure it then to do the same thing as the internal button?

[ascillato]

For button2 do as the same as button1.

But, if for the button2 you need to have a different topic, you will need to use rules as the example: https://github.com/arendst/Sonoff-Tasmota/wiki/Rules#13-toggle-a-relay-only-when-holding-the-button-for-2-seconds

[ascillato]

Have you managed to solve your issue?

[benzino77]

The HOLD feature is only available if you set your pushbutton as button in the module configuration.

I think switchmode 5 and switchmode 6 can do the trick with the HOLD functionality for a switch, but I believe that still you need rules (as @ascillato suggested) to do what you want with the second input.

[ascillato]

@benzino77 You are right! The HOLD feature is available also for switches if using switchmode 5 or 6.

Thanks for pointing that :+1:

I have updated the example of the wiki: https://github.com/arendst/Sonoff-Tasmota/wiki/Rules#13-toggle-a-relay-only-when-holding-the-button-for-2-seconds

[benzino77]

@ascillato the example you provided covers two situations for button:
when the button is HOLD for two secs
rule on button1#state=3 do power1 2 endon

and when button is pressed once:
on button1#state=2 do delay endon

What is a state number for "double press"?

[ascillato]

What is a state number for "double press"? [ FOR BUTTONS ]

There is not a state number for "double press". It is designed that double press will toggle the relay. More information at: https://github.com/arendst/Sonoff-Tasmota/wiki/Control-other-devices

In the case you want to avoid the double press feature you can configure your button as switch and also set the switchmode that fits you (like switchmode 5 to make it behave as a pushbutton) [SWITCH does not have double press ]

Again, Thanks for pointing this as the explanation was required. Updated the example in the wiki. Thanks :+1:

[twieland]

thanks for your help!

the example works, but if I understand correctly there is no way to get three different actions done with single press/double press/hold with an external button?

[ascillato]

You can have all 3 actions but defining your GPIO as button. In that case the double press will toggle the relay.

There is also an option to swap the actions of the single press and double press.

So,

_BUTTON WITH 3 DIFFERENT ACTIONS_

• As an example:

_[ assuming gpio0 is configured as button1 ]_

And that you want:

single press: Turn relay 1
double press: send a mqtt message
hold 2 secs: send another mqtt message

buttontopic 0
setoption1 1
setoption11 1
setoption32 20
rule on button1#state=3 do pubilsh cmnd/topicHOLD/power 2 endon on button1#state=2 do pubilsh cmnd/topicDOUBLEPRESS/power 2 endon
rule 1

• Another example:

_[ assuming gpio0 is configured as button1 ]_

And that you want:

single press: send a mqtt message
double press: Turn relay 1
hold 2 secs: send another mqtt message

buttontopic 0
setoption1 1
setoption11 0
setoption32 20
rule on button1#state=3 do pubilsh cmnd/topicHOLD/power 2 endon on button1#state=2 do pubilsh cmnd/topicSINGLEPRESS/power 2 endon
rule 1

please note that setoption11 0.

_SWITCHS WITH 2 DIFFERENT ACTIONS_

Switchs do not have double press feature

• Example:

_[ assuming gpio0 is configured as switch1 and that you have a pushbutton connected ]_

And that you want:

single press: do nothing
hold 2 secs: toggle relay 1

switchtopic1 0
switchmode1 5
setoption32 20
rule on switch1#state=3 do power1 2 endon on switch1#state=2 do delay endon
rule 1

Added this set of examples to the wiki at rules and button usage. Thanks for pointing this out. :+1:

[twieland]

Thank you, that's perfect!
FYI, the piece I was missing is setting the configuration to "generic" and the external button on GPIO14 as button1. Maybe that'll help others in the furture

hi, i'm new with github. i found this one quite similar with my issue. I flashed the 2.4.2 fw to nodemcuv1, then i selected the sonoff_basic in configuration. the relay2/switch2 on gpio4/14 work perfect, however, the relay1/swith1 on gpio 12/0 work as push button (momentum switch). I tried with swithmode1 1 but it still work as button push. are there any way to change its behavior, even with modification the code inside?

[ascillato]

Switchmode is for switches. In a sonoff basic the pushbutton in gpio0 is configured as button. So as to configure it as switch you need to select generic as module. If you are using a nodemcu you need to use generic module
