IoTorero enters the ring If you've spent any time browsing pre-flashed smart home tech online, there's a good chance you've come across IoTorero. And if you haven't, let us introduce you! Founded in 2020, the company (formerly Athom Technology) was tinkering with ESPHome right out of the gate. Their new name is a nod to the Internet of Things (IoT), but unlike standard IoT gadgets that stop working if your internet drops or a company closes its servers, IoTorero champion open source firmware. Other smart devices run manufacturer-written software, which is tuned to work well with Home Assistant for certification to the program. IoTorero go a step further to make sure their tech is accessible for all: all seven of their certified devices are pre-flashed with ESPHome, meaning there's no installation required - the devices will integrate into your Home Assistant setup straight out of the box. And because their devices are genuinely open, you can always tweak and customize them if you want to. "Since inception in 2020, IoTorero (Athom Technology) has been dedicated to the research, development, and manufacturing of open source smart home hardware products. We provide Home Assistant users with high-quality devices pre-flashed with ESPHome firmware. By joining the Works with Home Assistant program, we ensure that customers can select and purchase our products with complete confidence." - Aiden Tang, CTO and Co-Founder, IoTorero That same spirit of openness carried over to last year's Community Day, where IoTorero donated a stack of samples for attendees to try - a gesture we loved to see, and one that speaks to how seriously they take supporting our community 💪. It shows up in their approach to code, too: IoTorero maintain a pu ## The triage is the product: running AI agents against Ethereum's protocol code DevFeed: [The triage is the product: running AI agents against Ethereum's protocol code]() Original publisher: [Read original article]() Author: Nikos Baxevanis Published: 2026-07-09T00:00:00Z Content type: article Language: en Sources: [Ethereum Foundation Blog]() Topics: [Artificial Intelligence](), [Ethereum](), [Security](), [AI research agents](), [Code](), [P2P]() Tags: [agents](), [ai](), [ai-agents](), [cve](), [ethereum](), [protocol](), [research](), [research-development](), [security](), [security-research]() ### AI overview The Ethereum Foundation's Protocol Security team describes how it uses coordinated AI agents to audit Ethereum protocol code.
