A #SmartHome should be completely independent of any internet connection.

Diogo Constantino

@jwildeboer That's a different take, and I agree and practice it.

Jan Wildeboer 😷:krulorange:

@DiogoConstantino I have updated my toot to clarify. Thx for your intervention!

Yes. Serious question: How do I do this with new cars. I need a newer car. My 34 y/o Acura is showing its age.

There are a lot of interesting new cars, EV, Hybrids, etc.

BUT I am an older InfoSec guy.

I want zero connectivity. No GPS, no Bluetooth, no RF connectivity of any sort. No "Keyless" entry.

I have a smart phone. It has all the connectivity I desire or need.

I understand that an EV needs firmware, but that can updated manually/locally.

Thoughts?

As #IPv6 GUA addresses are assigned dynamically by all German ISPs, as soon as the Internet connection goes down, the #Smarthome is only functional until the end of the preferred_lifetime. ULA addressing helps a bit but brings other challenges.

No new car for you. Sorry.
New EU cars all have mandatory cell phone connection.

Same with PV battery storage. Only very few require no Internet connection.

@goetz Yep. One of the unexpected side effects of IPv6. Even less control over your home network. This was surely just a little oopsie

Jan Wildeboer 😷:krulorange:

@goetz I don’t use a car and even if I did, I wouldn’t park it in my livingroom, so I don’t consider it as part of my smarthome. @oldguycrusty

@goetz @jwildeboer Probably not MUCH of an issue as ESPs and Tuya devices (which from what I've seen account for a big chunk of smarthome devices) only support IPv4 anyway.

@jwildeboer even easier: no smart home devices at all!

Jan Wildeboer 😷:krulorange:

@acm_redfox So no internet at home? Sure. Possible. But not very common.

@jwildeboer @acm_redfox that isn't the same thing. We don't call a PC smart because it has a WiFi card.

Jan Wildeboer 😷:krulorange:

@LovesTha The premise of my toot was a #Smarthome with devices that use the internet. The reply was to have no connected devices at all. Which is not the same, obviously. So your reply makes even less sense, IMHO, and moves the discussion far away from the point I tried to make. @acm_redfox

@blindcoder
Esps with #esphome work fine with #IPv6 unfortunately they still need Dual stack.
What Jan says for no need for the Internet, I have the requirement that smart home devices need to work with #ipv6only to be considered worthy to be integrated.

@jwildeboer

@jwildeboer That's also the reason why #AVM made to ULA addresses default in the LAN in the latest software update of #FritzBox

Benjamin

@goetz @jwildeboer interesting. I mostly have tasmota flashed and from what I saw they claimed that the WiFi blob for the esp devises doesn't do v6.
Esphome seemed too complex for me yet so I haven't looked into that yet.

@blindcoder
You need to compile #IPv6 into the 8266 manually. The online tasmota compiler does not allow for this.
@jwildeboer

goetz 🚲

@blindcoder @jwildeboer

For ESP8266 you need to add:

# user_config_override.h:
```
#ifndef USE_IPV6
#define USE_IPV6
#endif
```

# platformio.ini:
```
; -DPIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH_LOW_FLASH
-DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH -DUSE_IPV6
```

This gives a GUA and LL #IPv6 addresses.
Unfortunately things like DHCPv6 or #PrivacyExtensionsforIPv6 is not available, due to #lwIP not supporting it yet.
