Some years ago I tried Denkovi products (wifi relay board: Wi-Fi Relay Module - 12 Relays, IO, WEB, HTTP API, SMTP, Telnet for another application and worked well.
But the relays from the wifi board doesn’t work in multiple mode (using digital inputs and logical command). Only one config can be set. Also the relay status feedback for HA is by pooling, which is a bad way to do.
In my lighting control I want to use push switches and the relay status feedback can be done by MQTT, that’s why I will try the smartDEN board.
Good news! The SmartDEN arrived.
I’ll post a detailed review in a few days, but so far first impressions are good.
I did a quick workbench setup for relays with pushbuttons on digital inputs (setup directly on module - it doenst depends on HA to work “offline”. It works great.
Also, I did the MQTT integration on HA and the module worked like a charm… the feedback time to/from HA <-> SmartDEN is very good.
First of all, sorry for the late reply! I am in the process of starting construction of the new house. So there are many things that take up time during the work.
In the meantime, I bought Kincony A32 board and testing togheter.
The relay boards I’m testing are very good. Good integration with HA, good operation and reliable, so far.
I’m going to use these boards in my new house. I gonna control ~150 light circuits (most are LED), 10 window blinds (external), some controlled outlets, solenoids, and others.
I’m intended to use Kincony boards, because of number of circuits, I would need buy a lot of 8 channel boards. Using de A32, the number decreases substantially.
I installed the KCS firmware and using MQTT protocol to talk to HA. It works like a charm.
My concern is about the lifespan of relay modules. However, this is a issue I would face on others market boards and suppliers. To prevent short life of the relays, I gonna protect some of them (those who gonna control critical loads like garden/wet lights/circuits, solenoids, using contactors and couple relays between load and boards.
@EarthK the relays are activated by the boards (the HA can be offline and everything still working) using the related Digital Input of the board. The cable from pulse switch will be awg 26 because they will be working on 12v.
