It depends how deep they are. I run into a depressing number that have just been caught up in the misinformation storm. Getting them to stop and think often helps recalibrate their thinking.
It doesn’t help much on those that are deep enough their ego is heavily involved.
That’s exactly what I do. I also have IoT devices that are still trucking along a decade later. I fully expect them to likely do a decade more.
Both Tasmota and ESPhome provide open source firmware for many IoT devices. They throw up a local API interface that other systems can talk to. Providing legacy support is as hard as using HTML put and get commands.
