Trump’s EPA wants to let data centers hide their air pollution

Just as new data centers face growing backlash from neighboring communities, the US Environmental Protection Agency (EPA) is about to make it harder for people to weigh in on any pollution those centers create. The EPA plans to toss out a federal rule requiring public notice and an opportunity to comment when certain industrial sites […]

Is Slate Auto’s new electric truck the EV Americans need?

EVs account for under 10% of total new-vehicle sales in the US, and the numbers are declining. From a climate perspective, that’s pretty dismal, especially because the transportation sector is the single biggest source of greenhouse-gas emissions in the country. One thing that could help turn that around? Slate Auto’s new truck—a vehicle that seems…

Tesla sunsets its Solar Roof tiles

Tesla has discontinued Solar Roof, its solar panels designed to look like regular roofing tiles, Electrek reports. Sources "close to the program" told the publication that Tesla has informed its third-party installer network that Solar Roof is no longer available to order, and that only conventional solar panels will be supplied going forward. While Tesla […]

The next big thing in hydrogen could be underground

There’s a hunt for new sources of hydrogen, and the gas (or at least the right conditions to make it) could be hiding beneath our feet. Hydrogen can be used as a fuel in everything from large trucks to planes to steelmaking. It’s often hailed as a climate solution because when burned, it produces water…

Support networks aim to help kids through the polycrisis

Sometime in the late 2000s, Pim Sullivan-Tailyour was sitting in the back of a car, headed toward her great-grandmother’s tiny town in the south of Thailand. She watched big mountains pass by out the window. She was just six years old but was about to be hit by an adult-size realization. “They were just quarried…

How much hydrogen awaits us underground?

In the 1990s, Barbara Sherwood Lollar descended into the Kidd Creek mine in northern Ontario, which cuts more than three kilometers into the ancient root of North America. There her team of geochemists found water that had been confined underground for more than a billion years. This ancient brine turned out to be a habitat…

What’s behind this summer’s heat, and why 2027 could be worse

This summer has been a scorcher for much of the Northern Hemisphere. June and July marked the hottest two-month stretch in Europe since record-keeping began. The contiguous US endured its hottest month on record in July. South Korea saw its highest-ever recorded temperature. The heat isn’t over yet, but some scientists are already looking ahead…

Space mirrors could ruin astronomy — and your eyes

Solar energy, at any time of day or night - that's the dream of space mirror projects. Futurists have been imagining satellite mirrors that could reflect the sun's light onto the Earth's surface for over a century. Russian scientists experimented with the concept in the '90s with the Znamya project. The idea is to put […]

Nitecore’s latest power bank is the lightest and most compact yet

There's two things you should know about me, your intrepid reviewer: I hate the feature creep associated with modern power banks, and I love shaving grams off the gear I carry when backpacking, bikepacking, and trail running. So imagine my delight when Nitecore released a new generation of its ultralight NB10000 battery. After a few […]

Shelly in Home Assistant: Local Switching & Energy Metering

I didn't put Shelly Plus 1PM and 2PM behind my wall switches for the app or the cloud. I put them there because each one quietly does two jobs at once: it switches a circuit locally, and it measures exactly what that circuit draws. The moment I had them wired in, every light group and every roller shutter in the flat became both controllable AND measurable in Home Assistant — with no separate energy meter and, deliberately, no cloud in the loop. This is the part most Shelly write-ups skip: the metering isn't a bonus, it's the reason to use them. This is how I set them up, kept them fully local, wired the physical switches so they still work like switches, and pulled per-channel energy into the HA Energy Dashboard. Why the Plus series for in-wall use The Plus 1PM and 2PM are Gen2 devices. That matters: they speak a local RPC API over HTTP and WebSocket, they're supported by the native Home Assistant Shelly integration out of the box, and nothing about them needs the internet once they're on your Wi-Fi. The 1PM is a single relay with power metering — I use it behind light circuits. The 2PM has two relays with metering and a dedicated cover/roller-shutter mode — that's what sits behind my shutters. The catch you plan for up front: both need a neutral wire in the switch box. Older installations often don't have one at the switch, so check before you order. If the neutral is there, the rest is easy. The first thing I change: kill the cloud, pin the IP Straight out of the box I do two things in the Shelly web UI (just browse to the device's IP). First, I disable Bluetooth and Cloud under Settings — I don't want the device reaching out to anything, and Home Assistant talks to it directly on the LAN. Second, I give it a fixed address via a DHCP reservation on my router, so the native integration never loses it after a reboot. That's the whole hardening story. No firmware flashing, no third-party firmware — stock Shelly firmware with the cloud switched off is already a fully
