#ambienthvac — Public Fediverse posts

remember that air-exchange based HVAC assistance stuff I used to talk about all the time like two years ago?

hasn't gone anywhere, still working.

29°C composite outdoors, 23.5°C composite indoors, no AC running.

Also I should note we have a server farm and it's obviously indoors and contributing to indoor temperatures

Here's each set of sensors in °F and °C for your convenience

i keep bringing it up because people can do this and it's cost negative in less than a year

That's not nice! That's not nice at ALL!

if you're wondering how firework smoke shows up in my HVAC assist system

oh yeah, i got the new weather sensor shield painted today so it's out tonight, let's see how she do

the funny side note is that the two AA batteries in the sensor, installed two years ago and operating continuously since then, test as nearly full charge. that's what the remote software was telling me but i was having a hard time believing it. BUT WHELP

wanted a couple of pics of the temperature and humidity sensor I printed before hitting it with a coat of spray paint for hopefully improved durability

one down only like... six? more to go?

chug chug chug

print print print

these are like 7 hours each because they can’t be in fast mode because they have to have decent tolerances to stack together right :/

"fall" mode is new btw

basically means "ignore the windows and open the air-exchange system on a distributed timer for fresh air but not _too_ much fresh air"

Here, have a really, really niche printable solution

As part of my ongoing air-exchange-based HVAC project, I have an outdoor air quality sensor from Ambient Weather (disclosure: nothing to disclose, no sponsorship, I bought it). It’s battery/solar powered, and that’s fine… except for the part where that doesn’t work here in the winter. We’re too far north and too dark.

But […]

I made a thing!

As part of my ongoing air-exchange-based #HVAC project, I have an outdoor air quality sensor from #AmbientWeather (no sponsorship, I bought it). It's battery/solar powered, and that's fine... except for the part where that doesn't work here in the winter.

But since it plugs in to charge and keeps working when plugged in, winner winner chicken dinner, right?

NO! Because first you have to take the bottom off the case, then the charge plug sticks directly out from the bottom facing down, like a goddamn Apple Magic Mouse.

I can't fix the mouse, but I can fix _this_, and I have made a printable tray and rack system to let you use it that way. Enjoy!

Nice to see my air-exchange HVAC assist system sensing air-quality issues overnight, overriding the temperature- and time-based system, and keeping the air-exchange system closed, exactly as designed.

code lives on github, btw

another new, smaller ambient-hvac drop

Did I already push out another new version of ambient-hvac, this one adding a new seasonal mode for spring/fall? And only a day after pushing out the biggest update since launch?

Yes. Yes, I did. ^_^

Did I already push out another new version of ambient-hvac, the second in two days, this one adding a new seasonal mode for spring/fall?

Yes. Yes, I did. ^_^

massive new ambient-hvac drop

aw yeah 0.6 is in the HOUSE

huge code refactor, it has a config file now, and it has all the added functionality i’ve been talking about for the last few months. it is i will admit still kind of a mess but despite that it still grows ever more l33t. enjoy!

ambient-hvac air quality control at work

Oh hell yeah the air-exchange vent did the thing! It’s probably not the first time but I did just roll out the code over the weekend and it’s the first time I’ve caught it doing this:

log file output showing ambient_hvac noticing the air outside is better than inside from a 2.5nm ppm standpoint, and opening the air exchange vent to let outside air […]

100% live data

100% live data, folks. Got the new controller hooked up to the actual, real air-exchange system and we’re up and running. 😀

Semi-passive/air-exchange HVAC assistance system running against live data on real hardware. We’re in summer mode and it’s warmer outside than in – building composite temperature 22.0°C, outdoor 22.5°C – so the […]

Guess who has AUTOMATION going? :D

So I spun up my air-exchange HVAC system’s test platform in “summer” more with the new air-exchanger controller board set up and programme, and it checked all the temperatures, recognised it was cooler outside than in, overrode the time-of-day basic programme and wirelessly opened the vent to bring in cooler air!

Or turned on the […]

Okay then. It works! The wireless relay block works!

I am finally going to get remote control going on the fresh air intake vent – with expansion for three more. (And I have plans for those relays! Or at least ideas. Ideas. Yes. At least ideas.)

It’s not much to look at right now. I mean, it’s a little block of relays with a wifi transmitter on it. But it’s arduino programmable, which means that […]
