[afnog] XLAT646 deployment

[JORDI PALET MARTINEZ]

I've a similar setup to control also my heating/DHW,  and electricity ... replaced myself most of the electric wiring, and devices in the electricity distribution panel, so they have WiFi and can measure consumption, etc.

In addition to that, 2 years ago deployed 6Kw solar, and made my own LFP 80Kw battery (90x3,2V cells and a Batrium BMS  https://twitter.com/jordipalet/status/1389193991716020227) ... next step, summer job, is to add 1Kw PVs, replace my 20 years-old gas heating/DHW with an aerotherm system (government is funding 45% of the cost), so I can take more advantage of my own electricity. I "sell" the excess to the electric company, but the Spanish law compensation system is not good, is monthly basis, so I've excess electricity 8-9 months per year that I never get paid for and 3 months that I pay some electricity + the gas bill. Now I will change that.

My previous monthly electricity bill was 120 euros, now is below 12 euros ... My yearly gas bill was around 500-600 euros, will turn into 0 and will increase something like 20-30 euros the electricity bill for 2-3 months when we have not sufficient sun.

All that is controlled by self-developed monitoring with Influx/Telegram/Grafana ... and now I'm working in an interface between the different electric meters (in the WiFi MCBs and MCBOs), so I can tell the aerotherm to "slow-down" for some minutes when there is an excess of energy demand in the house, for example when I turn on the oven ... so to avoid asking the inverter more than continuous 5-6 Kw which may trigger a security disconnect or even trigger the electricity company switch, etc. (my contract was 4.6 Kw, now only 1Kw with the electricity company during the day, 3Kw in the night - in case there is no sufficient sun, so I can recharge battery at the lower energy price).

    It is happening here, if you are Nishal, Mark, Andrew, Edrich, Edward, 
    Ben, e.t.c. But just like you, Randy, Philip, Job, Owen, e.t.c., we are 
    not representative of the wider demographic in any of our regions. I can 
    tell you, exactly, just how much electricity every circuit breaker in my 
    house is currently using on a per-second basis; I don't ever expect that 
    to become the norm at scale.

    Having a ton of devices and sensors in the home does not automatically 
    mean that they would be connected on separate VLAN's. This goes for all 
    regions in the world.

    It is very likely that any new CPE's being deployed will have the 
    capability of supporting multiple VLAN's, and if it all goes to plan, 
    even a CLAT. But that doesn't mean that the customers will actually know 
    about all that, or even care enough to figure out how to enable it.

    All this stuff is great, but we need to remember how simple users 
    approach the problem. They just want things to work, and can't be asked 
    to deal with all the fuss. That's our problem.


    > If the African ISPs take advantage of choosing a good CPE *now* which is almost the same price, they are making their investment "more" future proof, specially if that means saving IPv4 addresses and using that money for deploying IPv6 with better CPEs.

    You need to remember that in Africa, the majority of users that access 
    the Internet do so on or through their mobile phone. Fixed line services 
    are on the rise, but they pale in comparison to mobile-based connectivity.
