This relay module has a microcontroller as the control element. There are some units that have this uc not programmed. The symptom is a flashing diode and a flapping relay. There are also some which have the wrong resistors.
However, to get it working on a Tasmota or ESPeasy, read this:

If you find it unprogrammed I have somewhere the batch and program to load into this uc.

Simply connect with a cable to the rs232 port of the ttl and test by sending the commands A00101A2 to switch on and A00101A1 to switch off the relay. The first version works on 9600 and the second on 115200.
