Hey everyone, I recently picked up a Eureka vacuum cleaner, but unfortunately, the box didn’t include a user manual. I’ve been trying to figure things out on my own, but some of the features and attachments are not that straightforward. For example, there are several cleaning modes, and I’m not completely sure how to switch between them properly. I also noticed that the dust container has a couple of release points, and I don’t want to risk damaging it by forcing anything. Does anyone know where I can find a reliable and clear manual that walks through setup, cleaning, and maintenance steps? Having one would make things a lot easier, especially for keeping the device in good condition long-term.

I have two of these plugs (possibly 3) that are broken. One would not turn on the relay. I tried updating the firmware via OTA and got stuck in SAFEBOOT mode. I did a "reset 1" and no change (came back in SAFEBOOT. I did a "reset 2" and it did not come back. Nothing at all. No lights, no access point, no response to ping, no web UI. I tried plugging/unplugging 6-10 times quickly, no change. I tried holding the hardware button down for 30+ seconds and nothing. The other one I have the relay appears to have stopped working. It would not stay on and kept shutting off. Now I cannot get it to turn the relay on even under just a lightbulb load. Tasmota is working and I can toggle but nothing is happening. Is there a way to open these devices to inspect or access for direct firmware upgrade? I didn't want to physically break into it, not sure if they are glued or should they pop apart? Unless someone has other thoughts on how to revive them? Thank you! -Tim

This is probably an odd question, so here's some background: I have a particular type of commercial garage door opener that operates at 320Mhz. This is unfiltered, and basically takes anything that's on that band as input. If the proper codes aren't there it doesn't work, of course, but if you've got something that broadcasts on or around 320Mhz it will light up the "I've received a signal" lamp on the device. It's wide enough that X10 RF controllers, car fobs on 315MHz, etc. will light it up. Some years ago when the ESP8266 and ESP32 chipsets became cheap and available, I bought a bunch of devices for experiments and other electronic goodness. I spun up a few devices that would read humidity and temperature - this was before smart home stuff really got super cheap and available. While the devices I designed worked, I noticed that putting more than a few of them on the air knocked my garage door opener off. The received signal lamp was on all the time. All I had was a SDR stick, so I tuned it to 320MHz, and right there was a giant RF noise spur at 319.98MHz. This was overpowering the opener's radio. (This noise is in the FCC filing, so it's my fault for not looking.) However, I've purchased some of those cheap "weather displays" from chinese vendors, they use an ESP chipset but don't seem to have this problem. My question here: Has anyone had issues using Athom ESP devices with a garage door opener that operates at 320MHz? In particular, Linear (company) makes gate and door openers that operate here, and only here. If you have an SDR radio, it's easy enough to see the noise by tuning your device to 320MHz with a few MHz of bandwidth and observing the waterfall.
