The unit is well built but came with no documentation and no links to any on tindie or on the creators website. I was unable to get the item to function properly. The web interface was not working and the manual button did not engage the relay. On power-up the unit would simply toggle the relay continuously every few seconds. After about an hour of tinkering I reflashed the firmware.
The unit performed exactly as expected after it had been reflashed.

thanks for your review. I have left a link to the first start pdf with my shipping message and It should be visible in your order details. Tasmota has a factory reset feature, by holding the (mode) button for 40 seconds it will reset everything, there are also other modes connected to the button, but this is well documented on the tasmota docs.
I'm going to be using the TeHyBug to monitor the the workspace under our acquarium, to detect any leaks (for a couple reasons, a simple water flood detector won't work; humidity sensing is best). So I hooked it up with some off-the-shelf packages to provide everything needed.
