Re: Can Raspberry PI triggering power meters tripping off?

If it’s just the main RCD tripping it can be pain to find which device is causing the problem. This is the reason why I have 10 RCBOs, one on each circuit. Makes it easy to isolate a problem and also put offline any section.

Reserved addresses (they are NOT static addresses) on a router can give just as much pain as real static device addresses. Just wait until you change your router.

Be aware that is you put the Pi-Hole box as the first DNS server and a second address for another DNS server the second address is not a standby for the first. The way DNS works either could be selected. I run 2 Pi-Holes to overcome this problem and to give redundancy. Also any devices with a fixed ...

Re: Is My Cable Eligible to Power A Raspberry Pi?

You cannot overpower a devices, it will only take what it needs. So if you used a 10A 5V supply it would be perfectly ok. This question has been raised many times in connection with the iPhone, mine charges ok from an 87W Mac power supply!

Re: connect two PIs using straight Ethernet cable?

As long as it’s wired correctly, a four wire cable should work, but only at 100M. I’ve seen lots of bad cables dropping back to 100M when the interfaces used are 1G.

Re: Pi Hole

A few things to remember with Pi-Hole. If a device has a DNS address in its fixed IP statements then this will be used and bypass Pi-Hole. It’s best to run two Pi-Holes for contingency. You can fix then problem of bypassing Pi-Hole if you can put code in your router. I have my router set to use Ph1 ...

Re: Enforcing Pihole usage

You cannot just put the Pi-holes IP address in your router. Users will only get given it if they do a DHCP request. It’s easy for people to bypass by just hard coding a DNS address in their device. The only way that I know of that you can guarantee all DNS requests go to your Pi-hole/s is to put cod...

Re: Pi-Hole

I use twin Pi-holes for redundancy and it works exceedingly well. One thing to watch out for is that uses can bypass Pi-hole by setting their own DNS servers in their device. I get around this by trapping all 53 data-grams in my Ubiquiti router and redirecting them to the Pi-hole servers.

Re: Measuring number of devices connected to a router python

My Unifi WAPs with their software running an a Pi does this nicely. You can have 4 SSIDs on each radio and assign users to a particular SSID. You can get data rates, usage and time used from the software and data is collected in a DB so you could probably also analyse it too.
