thank you fast delivery ..i add extra payment 20riyal
Great product, first relay flicker on boot (default setup) but it can be fixed by connecting first relay to some other (GP)IO (I connected it to IO15). Instead of jumper, for first relay make wire and connect it to IO4/5/15.. Flashed with Tasmota and it works great.
Received damaged products, packing was very poor
Good
one relay is connected to IO16 and is always turned ON when powered ON, but fortunately IO2 or IO15 thru-holes are available
