Very cool, only 4 wires nice!

For 16 Channel I2C Electromagnetic Relay Module IoT

Got some of those boards. I use them with Raspberry Pi4 and Python.
Here is a easy code to switch the relays with 16 Buttons with TKInter GUI:

import tkinter as tk
from smbus2 import SMBus

I2C_ADDRESS = 0x22 # Adjust the address as needed
bus = SMBus(1)

# Set the configuration word to configure all pins as outputs
bus.write_word_data(I2C_ADDRESS, 0x00FF, 0x00FF)

# Initialize relay states (all off, since all bits are HIGH)
relay_states_1to8 = 0x00FF # Byte for relays 1-8
relay_states_9to16 = 0x00FF # Byte for relays 9-16

def toggle_relay(relay_num):
global relay_states_1to8, relay_states_9to16
if relay_num < 8:
relay_states_1to8 ^= (1 << relay_num)
else:
relay_states_9to16 ^= (1 << (relay_num - 8))

# Write to the output registers for all relays
bus.write_word_data(I2C_ADDRESS, relay_states_1to8, relay_states_9to16)

app = tk.Tk()
app.title("Relay Control")

buttons = []
for i in range(16):
button = tk.Button(app, text=f"Relay {i+1}", command=lambda i=i: toggle_relay(i))
button.pack()
buttons.append(button)

app.mainloop()

Equipamento muito bom, parabéns

For PWM 16A 3500W Triac Leading EDGE Dimmer 50HZ 60HZ

Estou utilizando o PWM 16A 3500W como gestor de excedentes, funcionou muito bem e voltaria a comprar sem problemas

Nice board

For WIFI 8 Channel Electromagnetic Relay Module

Board itself looks well made and works as expected.
Converting to Tasmota took more time than expected, so leaving some tips for others
Somehow Wemos didn't get into flashing mode automatically, so I used serial flasher and had to ground D3 while connecting power, to get into flash mode.
Tasmota does not PCF8574A out of the box, so need to compile your own binary - https://tasmota.github.io/docs/PCF8574/ Issue is that default driver does not support I2C address of 0x27, so need to change xdrv_28_pcf8574.ino for yourself. There are multiple ways this can be achieved, I changed '7' to '8' in line 114 to include 0x27 into scan - https://github.com/arendst/Tasmota/blob/development/tasmota/tasmota_xdrv_driver/xdrv_28_pcf8574.ino#L114
Once you get custom firmware onto the device, use Generic module type, set D1- SCL, D2 - SDA and after a restart, you should get the "Configure PCF8574" page mentioned in the documentation. Had to check the "Invert Ports" checkbox for 'normal' operation.
