Review: Good, simple modules - These are basic SPDT relay modules with the relay controlled by IO0 from the module. This module doesn't have anything beyond the relay driver, so no coprocessors or anything to get in the way. I was able to flash the modules to Tasmota over serial in-situ and the Tasmota template was trivial to get working. I didn't try the stock firmware at all, I immediately reflashed them to Tasmota. The only downside I noticed is the trace spacing between the low voltage and high voltage side is a bit low, so I wouldn't trust this to isolate the 5v side from line voltage on the contacts. This module has a PC817 optocoupler on it, so I found this odd as someone was clearly thinking about isolation, but I guess module size won the battle or the circuit PCB was redrawn by someone who didn't understand why the PC817 was there. Not a big deal, though, as this is a wireless module that's not a problem, isolation for safety isn't needed. Just know that when planning the 5v supply, that side should still be insulated as if it's line voltage. I recommend this board as a simple, starter board.
Review: Great price on a viable solution. - Normal ESP-01S chips and a functional relay. Due to the relay control pin choice, the relay cycles on ESP power up. My use case was to monitor a garage door with a magnetic switch sensor AND use the relay to push the opener button. Acheived via ESPHome with little complication. Wires soldered onto the bottom of the relay board provided access to a spare pin for the magnetic sensor, as well as power or ground. I chose not to deploy the functional device because I didn't want a power blink to open all of my garage doors. This problem can be solved by rerouting the pins to use something different to trigger the relay. The easy way is to achieve this is to use a stackable header and bend the trigger pin over one slot. I chose to switch to an ESP32-s2 relay combo, and gained more capacity to add additional sensors. These relays function well, just not the best fit if you can't live with a relay cycle on powerup. Honestly in real world use the ESP-01S probably boots so quickly that the garage door opener isn't listening to the open signal yet.

### ⭐ bad design, 3v board with 5v relays wont work
*by K***K on December 21, 2025*

Bad juju.. not sure if its a bad batch or what.. but 5vdc relay on a 3v board is not going to work. i supply 5volts to the board, program esp-01s, it comes to life, i trigger GPIO0 , blue activation light comes on, but no relay, checking voltage at the relay shows 3 volts dc, not 5volts. while gpio 0 is active, i check supply voltage and it reads 5 volts.. yet relay pins show 3volts. the relay will never activate with only 3 volts.. someone screwed up big time.. all 3 of my boards are exactly the same. they all dont work. thanks for causing me a waste of time. . hopefully manufacture will replace them with working 5 volt relay modules, or i'll even take 3volt boards at this point. i can deal with either.. but i'm not going to swap relays on the boards. that's their job to supply the right relay on the board i purchased.
