Any powered buttons that will work with Tuya wifi bulbs?

Want to install some smart buttons on wall that one can press to activate lights.

Unfirtunately have 4 light switches which cannot be replaced with wifi light switches unless I install/chase brand new switches.

Using google to link my ewelink and Tuya devices.

Do I need any additional hardware?

Doesn’t a WiFi SSID come up called Sonoff or Tasmota?

Then you can easily recover it through the web interface.

Guide is here.

Sonoff T1 - Tasmota

Documentation (Wiki) for Tasmota
tasmota.github.io tasmota.github.io

Try the 40-second button hold to reset it and see if you can access the built in SSID.

Likely it’s just stuck on the minimal firmware. That’s the worst that’s ever happened to me with these things.

*****

You can flash it easily enough just holding pins in the holes without soldering but I don’t think you’ll even need that.

I tried upgrading Tasmota to the latest from quite an old version so it didn't work. Now there's no web interface and the WiFi LED on the switch itself is permanently on. And to top it off, pressing the button doesn't even switch the light off. Need some way to recover the switch.

Ok will try tomorrow morning and post back.
 

Device Recovery - Tasmota

Device recovery procedures
tasmota.github.io tasmota.github.io

None of these recovery methods worked.

I tried the 40-second hold button and also the power cycle 6 times and nothing.

The LED light on button 3 is on but the wifi light is off.

Do you guys think it's still possible to re-flash with a serial to USB adapter? And is it possible to do it solderless with a Sonoff T1?

usb-to-serial always works after a failed OTA flash.
I have no experience with the T1, first lookup how it normally is flashed, the photos should give you a good idea

Here is the T1.

See: https://tasmota.github.io/docs/devices/Sonoff-T1/

Looks like you can just hold the cables in place on the holes.

Ok, I've ordered a FTDI thingy from Micro Robotics, will only get it over the weekend.

Are there any good tutorial videos? Those guides are hard to follow for a n00b.

(EDIT. This seems decent:
)

I know the software side but I hate having to flash it physically.

Maybe a dumb Q but just want to get the wiring straight before I pickup the FTDI connector.

What's happening in this pic?

There's 4 wires from the FTDI connector and then the jumper wire from GND to GPIO0 is connected to the same GND that the FTDI is connected to?

Yes, you need to bridge ground + GPIO0 momentarily when powering it up to get it into flashing mode.
 
Does it need to be the same GND pad that the FTDI is connected to?

On my T1 I see there's another GND pad separate from the one where the FTDI is connected.

Does it matter which one I use?

Doesn’t the button short the ground for you?

Can’t you just hold as you power it up as with most Sonoff things?

There is a physical button on there but none of the videos or guides say to use it. The only one I've seen where the physical button is pressed before powering on I think is the Sonoff Basic.

I'm picking up my FTDI adaptor tomorrow so let's see how I fair.

Still shouldn’t be hard to do without soldering if you have a few good wires.

And as said earlier some prestik can help, but I’ve never needed that.

I'm gonna pick up some male to male jumper wires tomorrow while I'm at it. No soldering though.

Yup exactly what I use.

And make sure to set it to 3.3v instead of 5v.

Tasmotizer makes the software dead easy these days.
