Customer Reviews
Had programmed and in service in one hour.
uso T-relay per il controllo delle tapparelle e temperature di tutti i locali.
Like I said in the description it's a great little board. I use it for an automated plant watering system and keeping a bird bath filled. My only suggestion is adding or pre-purchasing ESP32's with a U.FL Connector for an external antenna. The short distance wifi is the only drawback of the board.
Works perfect!
I really like the T-Relay Board! The design and functionality are well done. The only thing that is missing on the board is an Ethernet Port. I've already suggested this to the team, and they're on it. Can't wait to see the updated version!
