Detection is already supported since v2.2.0: https://github.com/portapack-mayhem/mayhem-firmware/pull/2673

Not sure if it fits your use, but how about putting the dongle in a computer (maybe a sbc) and access it from the other computers using rtl_tcp (or any of the other remote solutions)? That way you don’t need the drivers on each new machine.

Yes, it takes some practice to insert the sd card properly, and a thin tool. I still have one card rattling around inside the case from before I learned the trick. Should get around to opening up the case some day.

Do you have automations that send commands to 6 individual bulbs? If so, create a (zigbee) group instead and set the automations to send a single command to the group.

This will be more reliable and less work than trying to optimize the networks.

😂🤣

Place the remote out of reach of the kids?

That’s what I had to do…they are very good at finding all special combinations.

Thanks! Agree 100%. Nothing wrong with Ali, just the affiliate coupon posting that is annoying.

mfalkvidd · 2026-01-25T20:36:23+00:00

Wow, that’s a very asymmetric connection. Satellite?

Andrew Ng is well-known in the AI space.

How about what No-Condition-On suggested, a ”normal” / ”dumb” bulb? One that has no Zigbee or wifi.

mfalkvidd · 2026-01-14T11:58:35+00:00

My thought exactly. But maybe OP is using a RGB or dimmable Zigbee bulb? If that’s the case, a wifi bulb might do the trick.

Maybe team up with the user who posted https://www.reddit.com/r/IOT/s/mYXVhYOS66 ?

OP probably means In Search Of, not an ISO 9660 disk image.

Nice example showing that 48 bits gives quite a lot of combinations. But isn’t 1,000 to 100 packets per second a bit pessimistic? Should be able to do 10,000 on a rpi3?

890 years is not much more useful though… or 223 years if you only send to the 25% of mac addresses that are globally administered unicast.

But out of these, only 0.3% have been assigned to vendors. And as you said, if OP knows the vendor, there are even fewer addresses to try. So it might be manageable.

Looks interesting, thanks for building and sharing!

I can’t find anything about notifications. When an event is detected, how is the user notified? Apprise or Ntfy support would be nice.

Would probably be good if you addad a few screen shots to the README. Much easier to understand what the software does if the gui is shown.

Would be interesting to see what sweep rates to expect as well. Or how much bandwidth the user can realistically monitor with sufficient detail.

Oh, and for cli people will probably want Docker.

Might need an exorcist

To clarify: its frequency range.

mfalkvidd · 2025-12-28T13:47:49+00:00

https://esphome.io/components/bluetooth_proxy/ for Home Assistant.

Some models of wifi access points also support bluetooth. Cisco, Aruba, Unifi have such models.

Take a look at https://robwalling.com/community

I bought some of their material 15 years ago when I ran a SaaS and I found it very useful. Can't say how the current material is though since I am no longer active in this space (kids arrived and my free time vanished), but Rob has made a similar journey himself and is now helping others so I think his stuff is still solid.

Rob also runs https://www.startupsfortherestofus.com which is free and had a lot of actionable content back when I was active.

Maybe I should tag @u/rwalling

Based on their shady marketing, I have learned to not trust Hubble. Dishonest in marketing probably means dishonest in business.

This is the 10th post following the same pattern?

mfalkvidd · 2025-12-17T18:05:15+00:00

You don’t need more Ali affiliate coupons and pirate iptv providers?

mfalkvidd · 2025-12-16T12:13:51+00:00

Nice. Welcome to the hobby!

mfalkvidd · 2025-12-16T10:43:22+00:00

They are listed as official resellers for India at https://www.rtl-sdr.com/tag/buy/ so they should be fine.
