This relay worked great and was very easy to flash with Tasmota which everyone who buys it will do anyway. I'm deducting a star for lack of documentation. As in the case, there is nothing but a link to a DIY article on the internet. This in itself wouldn't be such a problem if the screen printing on the PCB told you what all the various terminal connections were, which isn't the case.
