Thanks for your reply it really helps the video’s you linked I already found. and found that they where really helpful for understanding. Together with your experience I am probably going to experiment a little to(I like to make my own stuff to so not looking nice is less of a concern as long as it works). Thanks for explaining the few details I didn’t understand. I feel like they are a perfect tool for presence detection that together with something else are exactly what I need. Once again thank you for sharing your experience and knowledge
Interference never though about that good to know might go 60ghz then and get 3 for 180 degree coverage. Also they can look through walls? Also trough wood or concrete or only the american paper walls? As this would be amazing for my hallway where there is a staircase kind of in the way.
what esphome presence detection sensor?

what esphome presence detection sensor? - Lemmy.World
So I am looking to get precense detection in my living room. I think I want
mmwave as I do want to detect people that are sitting on the couch for example.
And I saw most don’t have a large distance and angle as my living room/kitchen
is 8m by 12m(in an L shape) so most with a 4-6m detection distance are not
enough. Also regarding the price I am looking at esphome with a hi-link sensor.
But I would like to get some recommendations if I should get a LD2420 or LD2410.
Some say the 2420 can’t detect a stationary target but the 2410 has less
range(6m vs 8m). So I thought place 2 LD2420’s for 120 degree 8m coverage in the
corner of the L with a esp8266. Would this work for stationary targets? (it
doesn’t have to be able to differentiate between the two just not be like a
infrared motion sensor). Also if you have done this and have found problems or
something to share please do so. Thanks for your sharing experience with one or
both of the sensors and your knowledge about this topic.
that doesnt seem to work i can only forget the network and see the encryption type
i forgot to mention i want to do it when i am not connected to them they are not mine but logins from family and friends that i want to all do without having to go to their house with both phones

looking to solve some minor problems i have with my new honor magic 5 pro - Lemmy.World
So i have since a few months a new phone the honor magic 5 pro and have some
things i am looking for and hope you guys might be able to help me solve the
problems i have i will list them from most likely you can solve them to least
likely. 1. i have loads of saved wifi passwords/names on my old huawei p20 pro
that i want to migrate to my new phone how do i do that (i currently don’t have
root on both phone’s but am willing to get it if it doesn’t void my warranty on
the new phone and doesn’t require me to do a new system install/wipe my phone
and doesn’t cost a crap ton of money (time is no issue)) 2. how do i optimize my
battery usage regarding refresh rate and resolution? put it on low or smart?
(both 60hz and low res is more than enough for me) also i have a app (track work
time) that checks my location often can i maybe limit its frequency in settings?
3. how do i teach the power management system to without me disabling it
(putting it off auto) in the settings not kill my mail apps and some other apps?
4. where is my wifi scanning frequency toggle in developers settings on my old
phone it only ran a wifi scan every 30 seconds or so but in dev settings there
was a disable rate limit switch. 5. do you know somewhere in the Netherlands
that has public wifi 7 so i can test if it works on my phone? 6. how do i map my
volume up and down buttons in the camera to something like manual focus or zoom?
7. in my camera app where is my megapixel setting or is there non and just high
res or normal? 8. can i in software (again i dont have root see question 1)
control my charging speed to limit it to something like 500ma instead of the max
a charger can supply? 9. is there a way to get an lower brightness than the
minimum on the slider? or will my display look just always display white at max
brightness(or what feels like it when its dark around me)? 10. is there a way to
get my 960fps 720p slowmo back from my 5 year old huawei p20 pro on my honor
magic 5 pro? Thanks for your help solving this issues for me or letting me know
if it can not be done.
Okey I see everyone telling me power will be 100w+ so I think I won’t do it as we pay around the 30-50 cents per kWh but I see why purpose made hardware is more expensive now
That is not for multigig yes for 1gbit this ain’t worth it but for 2.5 or 10 it is a bit cheaper €20 per 2 10g ports
Mining motherboard+ 10g network cards= cheap network switch?

Mining motherboard+ 10g network cards= cheap network switch? - Lemmy.world
So with Crypto mining being less profitable and miners selling their rigs for
cheap I thought how can I get my self a cheap managed network switch. I saw
mining motherboards with 12 PCIe 2.0 1x slots(4gbit bandwidth) and tought hey if
I plug in some cheap 10g 2port network adapters I can make my own network switch
with exactly the ports I need(SFP+ rj45). Put opensence on it and boom Managed
network switch with multigig(2gbit per port). Is there something I am missing or
have I found a way to get cheap multigig? Also can anyone who has a 10g only
network switch tell me what kind of power it is using per port so I can compare?
Thanks for debunking my idea and saving me a few bucks.
