Sonoff Touch LED

[LexPrima]

The Itead website adverts this with "Its LED backlight lets you easily find and turn on the switch at night." However tasmota seems do interchange these states. The LEDs are off when the switch is off.

I tried playing around with ledpower and ledstate but these only control the wifi indicator. And also either completely on or off when switch is off.

I have seen a possible solution on another website by changing GPIO_LED1_INV to GPIO_LED1 in the sonoff/sonoff_template.h file. Haven't tried this though..

That website is just a front for github anyway - thats this ticket #214

The touch has two leds. One connected to the same control line as the relay (in the middle) so that when the relay is on the led is also on. Unable to control it seperately from the relay.

The second led is the wifi indicator which my software controls with both commands ledstate and ledpower.

Those are all leds available on my touch so other than the wifi led I see no possibility for a "LED backlight".

Thanks for clearing things up

Quick question:
@LexPrima make sure to set the Module type to Sonoff Touch and not Sonoff Basic in Module configuration menu. Then the WiFi led is on when the switch is off (to help you find the switch in the dark :)) and vice versa

However i would prefer for the WiFi led to somehow reflect the status of the switch i.e. to turn on once the swtich has established WiFi or MQTT connection and reported Online to LWT topic, and turn off when offline? Maybe blink while attempting to connect?

I have found a way to turn on the led of the touchpanel (so not the indicator led) forever. This means it is always on, also in the dark.
I think this is better then the default behaviour, off when it is dark.

I have a touch EU version, with 1 button with this board:

If you want the left led always on, you have to cut the print track in the blue cirkel. Connect the lower part (which is going to the led) to GND.

For the led in the right and the middle go to the back of the print:

For the led in the middle, cut the right print track at the blue arrow. Connect the lower part of the print track to GND. I have done this at the read arrow.

For the led on the right, do the same but on the left print track at the same position.

Now the touch led is always on.

Is it meaningfull to add this to the wiki: https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-T1-UK,-EU,-and-US ?

@glsf91 can you make a picture or explain what you mean with "connect to GND?". Do you mean hardwire the track to GND? Can you show us how this looks like?

[glsf91]

@madradrakie
Yes, I mean hardwire the track to GND.

[madradrakie]

@glsf91 , can you maybe share a picture how you hardwired the lower part to GND. I would like to know were and how you attached to wire.

@madradrakie
You can see it at the red arrow, the big soldering you see.

[madradrakie]

@gls91, it worked! Thanks. Do you also know how to tweak the sonoff touch T2? In that version the buttons are at the right and left.

[glsf91]

@madradrakie, I don't have a T2 so I don't know.

[madradrakie]

@glsf91 thanks for your help anyway. 4 of my Touch T1 are now modified and glowing in the dark! :-)

I think the T2 works at the same way as the T3, the only problem is that the connection for the left LED is underneath the touch button which i can not reach.
