I built a Serverless Unclocker to bypass this using AWS Lambda and API Gateway.</p> <p><strong>Why use it?</strong><br> Zero Cost: Stays within the AWS Free Tier, avoiding expensive licenses.<br> Automated: No more manual user creation or dashboard assignment.<br> Secure: Handles public onboarding without exposing your ThingsBoard root credentials.<br> If you are tired of "resource scarcity" and manual tasks in IoT, this bridge is for you.</p> <p><strong>Check the Repo:</strong> <a href="https://github.com/DanielBustillos/Users-self-registration-Thingsboard-community-edition" rel="noopener noreferrer">https://github.com/DanielBustillos/Users-self-registration-Thingsboard-community-edition</a></p> <p>What other CE features should I "unlock" next?</p> <p>I love Thingsboard ⭐️</p> <h1> iot #thingsboard #aws #serverless #esp32 #makers </h1> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Ffwff45rbirc560i6sfgg.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Ffwff45rbirc560i6sfgg.png" alt=" " width="800" height="543"></a></p> beginners iot tutorial Juan Daniel Bustillos Camargo Wed, 21 Jan 2026 20:53:14 +0000 https://forem.com/danielbustillos/8tbmonth-why-compute-clusters-when-you-can-just-use-hexagons-4a7a https://forem.com/danielbustillos/8tbmonth-why-compute-clusters-when-you-can-just-use-hexagons-4a7a <p>Handling 8TB of mobile pings every month is a nightmare for traditional clustering. I spent a lot of time with DBSCAN—the results were great, but the compute cost at this scale is a killer.</p> <p>My current "lazy" experiment: Stop clustering and start indexing.</p> <p>I’m treating H3 hexagons as pre-realized clusters. Instead of running expensive algorithms, I’m letting the spatial grid do the discretization for me.</p> <p>If you’ve pushed spatial indexing to its breaking point at the terabyte level, tell me: where is this going to fail?</p> <h1> geospatial #bigdata #h3 #python #aws </h1> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fihnrsoqkd0d7rsrq732j.jpeg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fihnrsoqkd0d7rsrq732j.jpeg" alt=" " width="800" height="477"></a></p>
