Can I use esp8266 to directly simulate button?

[t0ny-peng]

Hi, I'm thinking of using an ESP8266 to control the desk. Its GPIO pin can be set to either 3.3V or 0V.

Can I connect the pin directly to the button? So that I can set the GPIO to 0 to simulate the button being pushed, and reset it back to 3.3V when I want it to stop.

Thanks.

I'm planning to do the same. I'm still searching for a good LIN lib to esp8266, but my idea is to hardwire a wemos D1 mini or a nodeMCU to it. My two concern right now is to find a LIN package to read the data, and if the current electronics can power a nodeMCU or not.

Had you any success?

Hey @slaesh, did you publish it or not yet?

I would like to do it soon but I don't have enough experience with projects like this one so I don't want to fuck it up lol.

BTW did you guys finally tried it? @left4taco @tg44

Not yet. Still interested in this project, but I had no free-time to possibly brick my working table...

@alfonmga @tg44 not yet finished.. covid crashed my plans and results in some urgent projects to be done.. currently waiting for some parts shipped over the sea.. and trying to print a case..

hopefully i will be able to tinker in a few weeks! :)

keep you updated!

Hi @slaesh what you have done look really good. Could you give more details about the interface of the board ? (restAPI and Mqtt) how do you setup the connection wifi ?

Does this hack works also for the RODULF standup desk?
