Re: Is it possible to clone 868 Rolling Code remote with raspberry pi

Thank you for your reply!

So even if the remotes are working by utilizing rolling code, i should be able to clone that signal?
Could you recommend some 868 module for raspi?

Could this one work? https://www.aliexpress.com/item/32962150714.html

Is it possible to clone 868 Rolling Code remote with raspberry pi

Hello everyone, simple question. Is it by all means possible to clone a 868MHz RF Remote control with a rolling code using raspberry pi? If i long press the remote key i could use that to pair another remote, that is to clone from one remote to another if the other remote is in cloning phase. Could ...

Re: Is it possible for RaspberryPi 3 B+ to power a 6V device

Thanks for the input. I've been researching optoisoloators but that would require me to remove a button from a remote and solder the optoisolator, right? At this point i was thinking of connecting wires to the button contacts itself and insure connection by maybe using glue gun or some kind of wax. ...

Packet loss/Jitter spikes on 5GHz WiFi - Raspberry Pi 3B+

Hello everyone, I've been experiencing annoying packet loss/jitter spikes on my RPi. It's connected to a 5GHz WiFi, which access point is in the same room as Pi. Maybe 5m distance (~16ft). It's not noticeable on normal usage. But when i stream video using steamlink from my PC, it gets really annoyin...

Re: Simple Thermostat ON/OFF Control Wiring

Exactly. In my case, it has protection if water temperature goes over 80 degrees celsius. It will shut itself off after some period of time if temperature doesn't drop or keeps rising. And it also has few operation modes that will keep that from happening. I will set the max temp on furnace itself, ...

Re: Simple Thermostat ON/OFF Control Wiring

I would not risk it with your level of knowledge as any error could fry the Pi, break the controller, burn the house down through incorrect controls or even kill you as mains voltage is deadly. I would look at capturing the signal sent via IR or Wireless between the units - lots safer for your heal...

Re: Screen randomly turns off, sometimes wouldn't even turn on during boot or reboot

So i would like to check in on this.

Issue seemed to be with an HDMI cable. Don't know why.
When i used the same cable to connect laptop or set-top box to same TV it works without issues.
As soon as i replaced the cable, issue disappeared.

Maximum RPi3B+ and RPi4B Network Speed

Hello everyone, I've been using RPi 3B+ for a long time and I'm loving it so far. One thing i have noticed, is it possible that network speed (both 5GHz Wifi and on Ethernet cable) goes up to 100mbps? I know that for Ethernet, RPi has 100MBit card, it's not a Gigabit one, so that's fine. I'm ok with...

Re: Raspbian is sending invalid ARP Response

Sorry for late response. Yeah, the problem was definitely due to ASUS changing OUI when acting as Range Extender. I should've notice this before. Didn't actually knew it would do that.
Thanks!
