Correct also tried with B1204 with BCE.
I can see switching with my multimeter, but as soon as i attach the relay the voltage drops.

Re: Control 5v SSR relay with ESP01 GPIO
thanx, trying:
I have a transistor: P45N02LD
Diode: 1N5406
20K resistor between GPIO and B
GND connected to E (coming from ESP01)
C connected to Diode >| other side to 5v
But relay is not clicking

Re: Control 5v SSR relay with ESP01 GPIO
Hi Any updates on this?
So situation is as follws, I want to control W11-1a2ste 5v, thorugh GPIO, problem is when directly connecting it to the GPIO and ground the voltage drops to less then 2.7 volt which is minimum to operate.
Is there a workaround to fix this?

Re: Control 5v SSR relay with ESP01 GPIO
Sorry someone told me ssr, it is indeed complete coming from a sonoff basic board, as the sonoff itself is broken i was hoping to reuse it with my esp-01.

Re: Control 5v SSR relay with ESP01 GPIO
Hi,
Would any transistor do? Do i also need to place a diode to protect the flow back?
How would ik be connecting the transistor i have 3.3v and gnd coming from the esp. The transistor has 3 legs so where does what go? Appreciate the help.
I’m not that familiar with electrical circuits.

Control 5v SSR relay with ESP01 GPIO
Hi, Would it be possible to control a 5v SSR relay from my GPIO? When I connect the rely it does not switch on seems voltage drops, while a common 1.2V pair of rechargeable batteries can operate the Relay easily. When I measure the GPIO at High it provides 3.3V but when Relay is connected i'm left w...

GPIO1 as output
Hi, I would like to use the ESP01 GPIO1 as output, so i can control something using GPIO1. Would that be possible and if yes how would the wiring look like. I currently have GPIO3 as input using GND and RX, if I want TX as output would i use GND and GPIO1 (TX) any resistors required. I understand th...

Re: ESP01 1CHANNEL Relay, help appreciated
Hi all,
Added 10k to r1 en hooked up 100uf.
The relay is working now as it was supposed to.
No more pulse during diconnect.
Thanx for all the help great forum!
Now worked to fix my next challenge to getting this in homebridge weer reed switch and relay control.
Cheers,
Hemant

Re: ESP01 1CHANNEL Relay, help appreciated
Hi,
I guess I can resure 10k from R2 and put it on R1.
100uf, could I use 1000uF en what would be the impact?

Re: ESP01 1CHANNEL Relay, help appreciated
By the way there is no current on the relay. It is used to simulate the pulse on the garage

Sorry r1 is 2k r2 is 10k which i removed to get the esp01s working on this board.
My solder skills are not that wel, other options?

Hi,
Already have a 15k between gpio0 and 3.3
Did alteady remove r1 10k from the board.
Where is gpio15?
Would it not break the board removing r2 2k resistor?

Hi, Thanks for your reply. I have a resistor between chpd and 3.3v 10k Also a resistor between 3.3 and gpio0 15k But did not solve the issue. Pluse is about .5 sec which is not much but enough to trigger the door. Where would the capacitor go? And what would be the spec of the capacitor 1000uf ok? W...

Hi M8's I have a ESP01 1 channel relay V1.0. This is hooked up to my Garage with 1 reed switch and the door itself to NO/COM. All works from a control perspective and I can open/close with DOMOtiz/Homebridge and Homekit. There is however only 1 issue, i get a small pulse during a powercycle which tr...
