  • OpenWRT is a different scope than opnSense.

    I have a few OpenWRT devices to cover WiFi in my home and definitely an opnSense on top of them for wan access and all the fancy stuff.

    OpnSense can’t to WiFi access point, thanks to BSD limited WiFi cards support, and definitely cannot fit on cots devices like OpenWRT can.

    As well as indeed opnSense is a better choice than OpenWRT for edge devices.

    While OpenWRT would do opsSense job, at least in part, the opposite is not true.

    I missed the business part… That make absolutely sense and gives out a different prospect. Here, you would be able to write off taxes all your home rig expenses I think.

    Yes, factoring in all energy costs (including the public television tax which is part of your utility bills) energy cost me 60€c per kWh.

    We use gas extensively, but for heating I use wood pellets with an idro-stove (heats the water that then circulate in the heaters).

    In summer I can use ac for those nights that doesn’t cool off, but during the day having 50cm thick stone walls never heats up enough inside. Winter are a different story, heating is on from 1 October to 1 of may, and here Home Assistant with per-room ZigBee thermostats and thermovalves is helping a lot to keep the pellet usage down to 2x15kg bags per day when its below freezing outside in daytime.

    Until we upgraded from 3kWh to 6kWh (at nice 300€ price point) we frequently had the power disconnected because the oven was on while drying hairs… Or washer and toaster… What a fun ride.

    3kWh is actually enough only for a condo, not for a house, but still it’s how it works here.

    All my hardware is refurbished from work, got it from surplus or things going to be dismissed. And way overpowered for the services I run (full arr stack, Usenet and torrents, WebDAV and filebrowser sharing, navidrome jellyfin actual budget homepage romm radicale and stuff I surely forgot).

    I even have two ISPs for redundancy because living in the woods make it unreliable, so FWA (5G 300mbps but capped) and FTTC (20 shitty mbps but uncapoed) it is.

    Thank you, very insightful.

    That’s a lot of power. Consider where I live having 3kWh for domestic use is standard. I have 6kWh due to the PV, and its highly unusual.

    Also, at my energy costs that would be ridiculously expensive, and way out of any justification, PV or not PV.

    Even only sustain 3kWh just for self host would be madness. And the cost would be unsustainable as well.

    The point that you “save” on the various subscription is moot, IMO, as those would never be subscribed in the first place at my house, so the “saving” is purely a luxury justification.

    No, for domestic use only that is pure madness. I admire, and envy, you a lot… don’t get me wrong, but that just prove you want / can splurge on fancy toys ad much as if you purchased a huge SUV just to go grocery shopping.



  • Interesting feature, but how often is that needed? O I never had such issue ever in my life.

    Is it something that can happen on such filesystems? Then I guess ext4 is far superior (/s).

    Jokes aside, that extra space with raid5 if by far more tangible and statistically sound than the bit flipping fearmonger.

    Which never happened to me so far.

    Frankly, if a pixel of a photo or a piece of a scene of a movie is corrupted, I will just never know, and never even notice. Nor a corrupted bit in a text note would be critical.

    I cannot think of any unreplaceable file of mine that would actually suffer from bit rot issue.

    Can you? Would be interested in which kind.






  • Yes I follow the 3 2 1 rule, one local backup on the hdd, one on another disk at home (connected to a openwrt router) and one offsite on my vps.

    I was using ssd for backup because I was dumb… I guess…

    Because needed extra space and added mindlessly the hdd without realizing I should have moved to a more efficient approach.

    I was impressed that HDDs where drawing so much, compared to overall CPU usage…

    And its over 20% saving.

    Yes, pennies, but nevertheless interesting.

    My energy cost is about 0.6€/kWh, so not trivial, but I actually run it on PV, so not really a money factor, more an energy efficient consideration.
