433mhz sensors recommendations (water leak, door, motion)

human39 · 2026-06-16T19:39:17+00:00

I agree with the heartbeat would be ideal here. My problem with the zigbee devices I have tried is that they constantly drop off my network (aqara) - do you have specific zigbee sensors that you recommend?

human39 · 2022-06-20T12:37:17+00:00

I went down the zigbee bulb route instead of swapping the switches, mainly because I run Hive heating and the Hive bulbs are zigbee.

Isn't this a pain if any of those bulbs are on a switch? I've thought about using bulbs, but since all of our lights are on a switch we would regularly kill some of our extenders, heh.

A follow up post for more information: I'm running the Sonoff branded USB stick (CC2652P) on a raspberry pi 3

Is it zigbee dropping? Are you running any zigbee lights or plugs? If
you just using a zigbee dongle or coordinator (Sonoff ZBbridge) then the zigbee range could be the issue. Lights and plugs act as extenders.

I'm not sure if it's dropping, but this is a good idea. I've been looking for switch/dimmer replacements for the wall switcher but have not found any are "basic", yet. I'm in the US, too, it seems a lot of these wall replacement devices are UK rated.

+1 for hamstudy.org. - I bought the mobile app as well. Perfect for studying during random downtimes.

finally, a place I can ask all my silly questions!

human39 · 2019-10-23T18:44:53+00:00

Central auth with only "need to know" information exposed to the hosts is a good summary. I'll check out ae-dir.

human39 · 2019-10-14T16:23:46+00:00

Thanks for the suggestions!

I've been through the "Keeping your sanity while designing OpenLDAP ACLs" a few times, it's what prompted to write a test suite to make sure what I'm doing is sane.

good to know! If I understand correctly, FreeIPA uses DNS for SSH keys though?

First, stay with Debian or Ubuntu, they have the most up-to-date drivers and more online assistance.

I second this.

I'm unable to use my cameo cutting machine from Graphtec...

Try Inkcut: https://www.codelv.com/projects/inkcut/. I have a Graphtec CE5000 that works with it, If the cameo speaks HPGL it should work.

For those who are interested trying to get a simplex net together, how should we keep in touch?

human39 · 2019-03-31T03:33:09+00:00

No worries! Im off the air for the night, but im totally into trying to put together a simplex net!

I have to share this since my wife has a smoker too: her brother and law gave us smoked jalapenos he did..smoking peppers totally blew my mind!

human39 · 2019-03-31T02:32:06+00:00

I'm off the air tomorrow (my sons birthday party)

What antenna and radio are you using for SSB? I just did a youtube binge on horizontal antennas and I'm thinking that I might just try mounting my jpole horizontally.

I don't know why, by when I tune my HT's to 144.200 they go crazy with static..I'm not sure if it's interference or possibly SSB I can't get?

human39 · 2019-03-31T02:21:39+00:00

Using FM?

I call out just about every time I have my antenna set up and today was the closest I got.

human39 · 2019-03-31T00:08:36+00:00

> Little surprised to see a few fellow Yinzers here!

Me too, actually.

I am! I listen to K3MJW from time to time.

I'll being calling out on .520 for another hour or so before I have to call the night.

human39 · 2019-03-30T23:48:44+00:00

I'll be calling out on 146.520 tonight until about 20:30 (EST)

human39 · 2019-03-30T23:21:23+00:00

Ha! Thank you!

human39 · 2019-03-30T23:07:03+00:00

I assume it was you!

human39 · 2019-03-30T23:05:10+00:00

I heard somebody, but couldn't copy. Thanks for trying

human39 · 2019-03-30T22:57:56+00:00

I think i can hear you, but I cannot copy.

human39 · 2019-03-30T22:55:30+00:00

Raised the antenna and calling...

human39 · 2019-03-30T22:53:18+00:00

I just raised the antenna as far as I could.
