@gohan That is a novel idea. Never tried it but i would think it should work as long as you can change the value on your controller. it should be simple enough to load the returning value into the sleep variable.
@Nca78 Yes, I was actually thinking using DIP switch (or even more easy to read thumbwheel switch) to give a unique ID to each node! As soon as I receive the extra radio modules I ordered, I'll test that.
@Grubstake I'm afraid you're right! But it's ok to have just a few days of battery life. As I wrote, it might be often disassembled and reassembled.
Hardware signing provide read back protection. If a node is stolen that use software signing, the hmac key will be available to the attacker and the entire network will be compromised. If a personalized atsha device is stolen, the programmed hmac key will still be unavailable to the attacker and the network will remain secure.
just to give you background of this, i have rpi based heating systems that i built and its working fine 99% but its all wires system temperature sensors are wired, relay for zone wired, relay for boiler wired, now i want to make this all wireless.
to make it wireless i m using mysensors and i have done all ground work done and it all works fine apart from
i. relay nodes are very unpredictable
ii. if i reboot my wifi router my gateway do not try to re-connect i have to press re-set button to get it connected to wifi.
hence i thought what if i have small little screen or tft on gateway that can tell me what is going on. i m testing wifi gateway but probably same goes to Ethernet gateway.
Here is my project that i m working on and trying to publish it PiHome
I did contact postmasters of free.fr with the errors you reported as well as a copy of the email I had receievd on my other email address. They replied to me that they need to receive the email directly from sender so that they can replicate the issue. IN parallel, I'm supposed to send the same email to a second address to let them know of the error.
The detailed process to be followed is:
resend the same email to my email address (****@free.fr) with email@example.com in BCC using the same tools than the "standard" email
then send another email to firstname.lastname@example.org to let them know the issue detailing in it the sender, the topic and the error messages received.
If you're willing to follow that process, of course I'd be happy (and maybe it can be useful for other French people since free.fr is a common email provider). But if you don't, don't worry, I understand you're very busy and you have more exciting things to do.
I was thinking trying to do it myself by utsing the email address they mentioned, but I'd miss the BCC recipient.
Sorry to jump into this duscussion late... I had this issue as well on some linux version. I downloaded it using sudo-apt-get install arduino and It didnt work for me either so I had to manual download it to get it to work. This was about 34-6 months ago though.
If you wan to run all nodes throug one gateway you need NRF24 on all of your devices. Both gateway and sensor nodes. But you only use the Gateway code on the Gateway and sensor code on the rest of them and only the Gateway needs a connection to your WiFi.
Max speed is 150kbit/s so it's 10 times longer TX time at twice the max current compared to nrf24.
That's the moment when the Livolo power supply can reach its limits so it doesn't sound like the right compromise to me. I never had problems while in RX mode.m with nrf24.
