ET#1. Review of cheap ESP01 / ESP8266 Relay V4 board. 5V USB operation. Tasmota compatible.
A quick over view of the V4 ESP01 relay board available from China. Compatible with Tasmota - a template already exists. A cheap and easy way to implement low voltage home automation.
As 'Clark' points out below: The separation between the low voltage side operating the ESP and the relay contacts is very small. Please don't use this for mains voltages. I'd suggest 24V max!
Available from a number of places including EBay and Amazon, I bought this from AliExpress. A link to the sellers site is below.
