There is the Arduino Plugin but start here for ideas : https://www.youtube.com/results?sear...s+with+Arduino

What the quick and dirty way to control Form-C Relays?

Get a Z-Wave socket module of your choosing, plugin a low voltage power supply and connect it to the coil. The Z-Wave module now controls the relay.

Or look for Z-Wave modules which have volt free contacts and do something similar, not a great deal different to the first approach.

AC? DC? Voltage? Can you describe the use case?

[David Johnson]

Form-C Relays are dry-contacts - do not care what the coil voltage might be - 3.3V, 5 V, 12V, 24 V - any will work. Ideally looking for at relay card/module with a USB or network I/F and a compatible plug-in. Seems simple enough!

Appreciate the feedback.

The Arduino plugin can do usb , Ethernet or WIF depending on the board you use and there are lots of relay boards available to.

I use these:

I've had them in service for years and they've been flawless.There is more info on the subject of relays (including the scripts I use to control mine) here:

There are many possible options to buy a relay board. It's sort of chicken and egg situation. Do you buy the board first and than look for plug-in or you find the plug-in first to integrate with HS4.

I personally use many relay boards for various applications. I use ESP8266 or ESP32 based relay boards, that connect to WiFi so that no extra wiring is necessary. I use either Zumungo (zumungo.com) or Tasmota (https://tasmota.github.io/docs/) software and control them using MQTT controls with Big6 plug-in for HS4.

I also played with I2C relay boards controlled by ESP32 board. I did create my own software to control them over MQTT. Once they are MQTT controlled than again I use Big6 to control them and read the status.

As far as software goes Tasmota (https://tasmota.github.io/docs/) is free and supports basic functions over MQTT.

Zumungo ( https://zumungo.com/ ) on the other hand is not free but is quite flexible and powerful for special applications. It does support MQTT, TCP, HTTP, UDP plus many special relay functions such as single pulse, delays, schedules, Sunset/Sunrise, sensor driven, temperature driven, hysteresis, kill function, virtual relays (that are at remote location) etc.

I don't agree with "chicken and egg" philosophy - I search for relays with good API and good support. Not cheap Chinese boards without any support or user manual in Chinese. You get what you pay for.

I write the plugins, so I find relay boards which support HTTP/REST API (plug-and-play, no Tasmota or MQTT) - and either ask the manufacturer to provide a sample for testing, or many manufacturers have online demo I can use.

If you check my AKWebIO or AKControlByWeb plugins - I support huge range of boards and controllers and can add any decent boards on request.
