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.

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))(edit i dont have acces to the wifi networks so qrcode sharing wont really work)
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.

So I recently bought a new honor magic 5 pro. My last phone the Huawei p20 pro was around 5 years old and started to show significantly less battery life. So I want to use this phone again for 5 years. But now I wonder should I keep the battery around 50% (65-35) and charge twice as often or should I 80-20 and charge once every two days? Is there any science that proves one is better than the other? Thank you for your information and sources.

hello guys i am wondering what are some must have iso's for a ventoy drive? and what size ventoy drive would you recomend (i am considering buying a 512gb, 1tb or 2tb tranced 220s nvme)

Back story: So i recently started my own "business" in computer support and i need a drive to put ventoy on (its currently on a 32gb micro sd card) so i can easily have memtest, ultimatebootcd and some linux distro's/windows install media and i am wondering if there would be any reason not to go with the cheapest per gb drive(2tb) as i could then also use it for some nice snappy file transfers. I am also looking to compile a list of iso's to put on it. As i mentioned before i already have a few things but you guys probably have more suggestions for iso's to put on a drive for repair\troubleshooting.

Thanks in advance for your advice on drive size and ISO recommendations.
