Right before Trump declared that the USA would start charging tariffs on incoming shipments and would remove the De Minimus exemptions, I got into Home Assistant. This has replaced some of my older semi-homebrew things that ran on proprietary hardware like RoomAlert devices. (I'm not knocking on RoomAlert stuff, it's very expensive but it's been completely reliable and for the target audience, it's fine because you're protecting 100s of thousands of dollars of hardware with a $200 investment. These are reasonably equivalent to the Shelly Plus w/add-on devices, but designed for an IT environment.) The problem with the homebrew stuff is that X10 doesn't report back because it was designed in a world where that wasn't needed. The 1970s were a different place. Yes, it's old, but there's so much stuff out there for it, and the desktop console controllers and remote controllers are unmatched in their function-over-form usefulness. The RoomAlert stuff, as mentioned, is expensive, requires wires, and uses older protocols that make it difficult to get replacement parts for unless you stay within their system. It's also not an instant response system, running a Lantronix pico-computer inside that has a Linux kernel as it's OS, and it has all of the failings of Linux in this regard - that of the checks the system does runs on what appears to be a CRON job. They occur every minute, so you can miss quick events. It is what it is, and I understood that going in to the lion's den, so it's not a complaint but an observation. Back to HomeAssistant. HomeAssistant has the ability to use many many protocols, including the cheap, available, and easily-implemented-inna-chip ZigBee system. One of the many protocols that ride along with ZigBee is called Tuya. This is a Chinese standard, which they created because the rest of the world sat around on their asses doing other things. Tuya has been adopted by many of the little wireless sensor manufacturers, but the chipset firmware is maintained by the Chinese company. Again - it is what it is, and if you don't want this to happen then don't sit on your ass expecting the food to be shoveled into your gob. Of course, the easiest place to get these sensors for HomeAssistant is China. They're cheap, and places like AliExpress offer them by the boatload. I bought a bunch right before the tariffs supposedly started. I needed some more recently for a new project, and decided to hesitantly place an order. Prices don't seem to be any different, maybe a little more, certainly no more than inflationary increases would cause. I received them, no tariffs, no import notices, nothing. It's business as usual. I ordered a bunch, something that I would assume might trip customs. Nothing. It went through much faster, arriving in less time than some orders I place here in the USA for stuff. I thought that tariffs were supposed to make all of this impossible to buy? Now don't get me wrong. I'd love to buy the stuff made here. That $4 water leak sensor? Sure, I'd pay $10 for it if it was made here. But, **it's not**. There's nothing really equivalent to a reasonably priced, wireless, runs on a coin cell for a year, deployable sensor like that. There just isn't. I've seen a few offerings, but they almost always are hand-assembled with COTS items, and cost 10x or more for less functionality and more power consumption. What has this done for anyone except make a crowing point for the administration? Is it actually doing anything? I've seen no real increases or changes anywhere save that a few of the more unusual items I used to purchase have vanished - but I would pin that on better customs enforcement as packages seem to be spending more time in customs than before. Regardless, I plan on stocking as many devices as I can, while I can.
