And Yet in Shelly2.5

Hi Shelly, I'm trying locally to interlock a Shelly2 without much success.

Why can't this be done locally from your software, it works in flashed to Tasmota, but not in your programme

Has DeepSeek is a thing i asked it. "code a shelly2 to interlock relays" did not work, Why?

To interlock two relays on a Shelly 2 device, you need to ensure that only one relay can be active at any given time. This is commonly used in applications like controlling a motor's forward and reverse directions, where both relays should never be on simultaneously.

Here’s how you can achieve this using the Shelly 2's built-in scripting capabilities:

### Step 1: Set Up the Shelly 2

1. **Connect the Shelly 2** to your Wi-Fi network and configure it using the Shelly app or web interface.

2. **Assign the relays** to the appropriate outputs (e.g., Relay 1 and Relay 2).

### Step 2: Write the Interlock Script

Shelly devices support scripting using the **Shelly Scripting API**. Below is an example script that ensures only one relay is active at a time.

```

javascript

// Define the relays

let relay1 = "0"; // Relay 1

let relay2 = "1"; // Relay 2

// Function to turn on Relay 1 and turn off Relay 2

function turnOnRelay1() {

Shelly.call("Switch.Set", { id: relay1, on: true });

Shelly.call("Switch.Set", { id: relay2, on: false });

}

// Function to turn on Relay 2 and turn off Relay 1

function turnOnRelay2() {

Shelly.call("Switch.Set", { id: relay2, on: true });

Shelly.call("Switch.Set", { id: relay1, on: false });

}

// Function to handle relay toggling

function toggleRelays(relay) {

if (relay === relay1) {

turnOnRelay1();

} else if (relay === relay2) {

turnOnRelay2();

}

}

// Add event listeners for relay changes

Shelly.addEventHandler(function (event) {

if (event.component === "switch:" + relay1 && event.info.output === true) {

toggleRelays(relay1);

} else if (event.component === "switch:" + relay2 && event.info.output === true) {

toggleRelays(relay2);

}

});

```

### Step 3: Upload the Script

1. Open the Shelly web interface.

2. Go to **Scripts** and create a new script.

3. Paste the above code into the script editor.

4. Save and enable the script.

### Step 4: Test the Interlock

- Use the Shelly app, web interface, or physical switches to toggle the relays.

- Verify that only one relay can be active at a time. If you try to turn on the second relay, the first one should automatically turn off.

### Explanation of the Script

- The script defines two relays (`relay1` and `relay2`).

- It includes functions to turn on one relay while ensuring the other is turned off.

- An event listener monitors changes to the relays and enforces the interlock logic.

This setup ensures safe operation by preventing both relays from being active simultaneously. Let me know if you need further assistance!

How do we set up the door, so I have the following

relay 1 protection setting I take it is set from http://YOUR IP ADDRESS /#/switch/0/settings/protections

relay 2 protection setting I take it is set from http://YOUR IP ADDRESS /#/switch/1/settings/protections

the web button interfaces button 0 Open/Close relay0/relay1

the web button interfaces button 1 Emergency Stop

Plus interlock relay, so relay 0 + 1 can not be on at the same time.

Finally, the web interface in Shelly 2.5 roller setup is easy and well documented.

"Shelly2.5 can operate in two distinct device modes: Relay and
Roller Shutter. Devices are initially programmed to work in Relay mode. The operating mode of Shelly2.5 can be set via the /settings"

Hi All,

I'm a NICEIC electrician working in England, after using your product's for two years, thought i would share some of the projects that i have used these in my professional capacity, one of the biggest problems with high tech networking switches from china is there all mostly fake, then in drops Shelly with safety marks from the EC standards has solved my biggest headache when a customer hands me a dimmer made in china.

1. used a shelly EM to monitor a supply, saved the customer thousands, because the extra capacity he had on his 3 phase supply.

2. used two shellies to local connected to each other for remote heating switch, adding switch live at boiler, worked like a charm

3. used a shellyPM and shelly button for outside socket to switch lights on/off.

also these 3 projects used there own local wifi, as customers wifi was poor. keep up the great work.

ongoing projects

rewire that customer requires a certain switches and sockets, but wants them controlled with Alexa or Google.

i will post in about 4 weeks time on 2nd fix with pics

i would also love more than 3 sensors,

on my Air Conditioner i have a shelly 1PM with the Addon

currently the temp sensor monitors

Thick Pipe from AC "Flow Temp"

Thin PIPE from AC "Return Temp"

Outside Temp

wish i could had Inside room Temp.

also name each sensor on there local network

anyway with a simple shelly it's helped my understanding my working's of the AC

Thanks
