Hi I’m new at Losant. I’m testing with Particle Photon following this link: > **[How to Integrate Particle with Losant](https://www.losant.com/blog/how-to-integrate-particle-with-losant)** > > This is a quick reference on how to connect Particle, a maker of inexpensive IoT hardware, with the Losant IoT Platform. Apparently the integration with Particle works, but I keep getting this error. What device id this error refer to? To particle device id ( From particle Web IDE ) or the one you find at Device tab on the top right? Thank you. ---

What is the error you are receiving? I don’t see one in your question. If you provide the error we should be able to help. ---

At debug tab, on top of the payload said: **ValidationError** Invalid device id: ```auto { "device_to_update": null, "globals": {}, "applicationName": "Moon", "flowName": "Moon Workflow", "flowId": "5c396a1deaf910000868d8b5", "flowVersion": "develop", "relayType": "integration", "relayId": "5c3969c5b6722e0007d0af60", "triggerType": "integration", "triggerId": "5c3969c5b6722e0007d0af60", "applicationId": "5c39691aeaf910000868d8b2", "data": { "temperatureF": "232.109890", "voltage": "1.611722", "name": "climate_reading", "coreid": "3e0039000247363339343638", "published_at": "2019-01-12T15:40:26.551Z", "ttl": 60, "data": "1.611722:232.109890" }, "time": "2019-01-12T15:40:28.880Z" } ``` ---

I’m assuming the device ID you’re trying to reference is at `device_to_update` on your payload, whose value is `null` in the snippet you provided. This would be the invalid device ID in question. If you’re following the tutorial from the link you posted, then your “Device: Get” Node must not be returning a Losant device. Can you paste screenshots of your Device: Get Node’s configuration as well as the tags you have applied to the device as you set it up in Losant? ---

It looks like your workflow screenshot didn’t come through; you do have the `particle_device_id` tag on your device, and it does match the value on your payload at `data.coreid`. So in order to return that device in Losant, your [Device: Get node](https://docs.losant.com/workflows/data/get-device/) should be configured exactly as it is in [this screenshot](https://www.losant.com/hs-fs/hubfs/Blog/how-to-integrate-particle-with-losant/device-get.png?width=1170&height=1650&name=device-get.png) from the article you mentioned in your original post. After that, you should have an object at the `device_to_update` payload path, off of which you can pull the Losant ID to use to update state in your workflow. Let us know if you’re still having issues. ---

OK, everything is working fine. The problem was that Device:Get node for some reason did not take correctly the settings. I went back to edit it and it worked. Thank you very much for tour help. ---

I just started with this platform. I am able to send data to Losant but yet I am struggling to get the slider value on my Electrone code. I understand that the slider should send itst value to the Broker but I do not find the way to set a variable for the slider. Can you give me some tip for do that? Thank you in advance.
