  • Welcome to the world of electronic gadgets. You’re right there’s nowhere near $100 worth of hardware in this thing. I’d also love a color touchscreen. But I’d rather a color touchscreen that I could integrate in HA than one running some proprietary cloud connected ThermostatOS.

    You could do that yourself- put an old tablet on the wall, run power to it, then get something like a zooz zen16 multi-relay or an ESPHome relay board to drive the hvac. Then the thermostat becomes a totally software defined virtual thing in Home Assistant that pulls data from a temp sensor in the room and controls the HVAC as appropriate.



  • Look up a product called Thrift. You can get it on Amazon. It’s a type of flake drain cleaner, comes in a bottle. Basically run your shower on super hot for a few minutes to heat up the pipe, then pour a bunch of this stuff down, and a bit more hot water. Leave it alone for a few minutes, then flush with hot water. Unlike Drano, this stuff actually works. Originally I found it on a plumbing subreddit. I’ve done it to my shower a few times and it seems to have a longer lasting effect every time, like it’s actually cleaning out the pipe.



  • You’re looking in the wrong direction.

    Let’s say you get an electric heater of that size. How would you control it on a thermostat? I promise you in a warehouse where that would be used it wouldn’t just be a circuit breaker you turn on and off.

    The answer is a relay, AKA a contactor. A small amount of power, either 24 volt or 120 volt at low amperage energizes the coil, which then pulls the contactor and engages a much larger power flow. With such a thing you could use any any thermostat such as a Z-Wave Honeywell T6 Pro or a Smart switch to control the big load.

    That said, such an electric heater will use an awful lot of power. You should really consider a mini split.
    Electric heaters are about 100% efficient. 5000 w of power input equals 5000 w of heat output. Heat pumps depending on the conditions can be 250% to 400% efficient. That’s because they aren’t turning electricity into heat, they are using electricity to move already existing heat in from the outside. Thus 5000 w of power input could mean 15,000 w of heat output.

    A lot of mini splits work with an external thermostat, but you don’t want to use them that way. Mini splits are modulated output, which means the compressor can run at almost any speed from 1% to 100%. They get maximum efficiency when working at about half output. So you want to be able to enable that savings. That means using the mini splits internal thermostat rather than an external thermostat that just switches it on and off.
    A great many of them use infrared, so you could just rig up an IR emitter that would send it commands. Then don’t use the remote control that comes with it and it will still have whatever state you just broadcast it via infrared.
    Alternatively there are some that have online connections and can be controlled via the cloud. For certain ones there is a replacement connection board you can get that replaces the Wi-Fi cloud connector with an ESP device enabling local control via home assistant. Do some research on this before you purchase.



  • You are confusing the spread of ideology with the spread of a conquistadorial government. Remember, most of the Germans who supported Hitler didn’t realize the Jews were being massacred. And we didn’t go to war to stop Nazi ideology, we went to war to stop Germany from conquering the entire fucking world through military means.

    The problem with using force to stop an ideology is that to the people who might follow that ideology, the fact that you care enough to use force against a belief system must mean there is something important in that belief system they should be checking out. Trying to stop an ideology with force only makes that ideology stronger, gives it validation.
    If you want to stop an ideology, ridicule it. Make fun of those who believe in it. Talk about how stupid they are. Talk about how they are morons not worth your time. Don’t give that ideology the validation of deserving force.

    The other problem with violence, is it prevents dialogue. If you are hitting somebody while talking to them, they are not going to hear what you are saying.


  • Hitler was defeated by being nice to him

    In that sense you’re right- some people only understand and respect force, and the only way to stop them is to use force against them. The analogy of Hitler might be compared to hardened criminals- being nice to a criminal won’t stop them from victimizing you.

    This is a different battle though. The small % of racists who want to burn minorities’ houses down, they must be met with force.

    Force doesn’t win hearts and minds though. Force is intertwined with fear- ‘if you do xxx, force will be used against you’. So it might stop some church burnings, but it doesn’t stop racism. Force doesn’t win ‘hearts and minds’. Force doesn’t convince a racist that they were wrong. It might make them too afraid to speak up, but it doesn’t win them over, and they will only take their message underground, where it will thrive.


  • Can you point to some other times in history where the threat of being beaten up has been effective in eradicating an ideology?

    I can point to plenty of instances where driving an ideology underground only fuels its growth…

    And look at the simple logic of it- if the guy in the big KKK hood says ‘the establishment doesn’t want you to acknowledge this’ and he then gets beaten up by mainstream majority people, you’ve just proved him right in the eyes of a would-be follower.

    It’s like if you found someone who knows nothing about astronomy, and told them ‘today the sun will rise at 7:15am and set at 5:43pm, and the moon is mostly made of bleu cheese’ you’ve predicted two things correctly so that gives you credibility when they consider the 3rd.
    If I said that to you, you’d say ‘you looked that up on Google, anyone can do that, and it’s well known the moon is made of rock’. But you are knowledgeable about astronomy (on a basic level at least).

    This works with the KKK person because chances are the KKK person has had limited or no actual contact and understanding with black people. So he sees news reports of inner city black people doing crimes and it becomes easy to convince him black people are somehow inferior. And ‘THEY don’t want you to know the truth’ is a powerful message for someone already interested in counterculture / dislike of the mainstream.

    That’s why Daryl Davis is effective- he sits down with the racist, who has a mental image of what a ‘black person’ is, and he’s not that. It’s like putting you on a rocket and flying you out to the moon and saying ‘okay we’re here, where’s the cheese?’

    And that’s why violence ISN’T effective- because the racist is expecting violence, so being violent only reinforces their belief.


  • I think we need both of these —punching Nazis and talking with them to change their views.

    Can you explain to me how punching Nazis works to reduce Naziism and racism? What is the mechanism of action? Like how specifically does getting punched make someone less racist?

    That is a genuine question and I’d love an answer.

    I personally believe that punching racists only creates more hatred. The racist will be angry at the one who punched him, and thus less open to anti-racist messaging.



  • I think that’s called conflict exhaustion. You’re sick of fighting, sick of holding your nose and respecting things and people you find repugnant, while there’s little/no serious progress in your direction, it seems like there’s more racism and hatred than ever. So part of you is ready to set the world on fire if it gets rid of MAGA and all the thinly veiled (or not so thinly veiled) racism and intolerance.

    Just keep in mind that the dark wolf actually serves those nazi punks. Punching them only makes them stronger.



  • No worries my friend. I know it’s hard, but it’s useful to always assume good faith.

    “The monster never sees a monster in the mirror. We all have good reasons and justifications for what we do.” – J. Michael Straczynski

    That applies to us too.

    I think it especially applied in 2016, first time in my life that all pretense of respectful debate went away, replaced with ‘unfriend me if you like Trump’ as a mainstream accepted even encouraged position to have.
    I talk to a lot of people who supported Trump. Most of them talked about tariffs, manufacturing, jobs, there was a dream of bringing back American industry and rolling back outsourcing. Yes there was some assholes, but there were plenty of good American folks who just wanted to keep their jobs.
    But if you listened to Democrats, the only valid reason anyone would vote for Trump is because they are a tiki torch wielding racist misogynist sexist xenophobic islamophobic basket of deplorables. The public discourse broke down for good, it was all just insults from both sides.

    Nobody saw a monster in the mirror. We only saw an opposition supporting a guy who was basically openly racist and creeped on his own daughter.
    But they didn’t see a monster in the mirror either. They only saw an ivory tower elite whipping ourselves into a frenzy over which bathroom someone uses while the middle class is dying.

    That’s why, in my opinion at least, it is always vitally important to generally assume good faith on the part of your opposition. Because if there is good faith, then we repair the cracks that are dividing the country. And if there really isn’t good faith, then we are all totally fucked anyway so it doesn’t make any goddamn difference.


  • People who I used to think were smart and empathetic were jumping on the “fuck your feelings” bandwagon.

    I don’t know your friends. But I’d argue there’s at least some reasoning for this.
    If trade policies like globalization have harmed your economic status, offshoring a lot of the jobs you’d previously held, and you were having trouble feeding your family, wouldn’t you vote for the person you thought could fix this? Wouldn’t you say ‘fuck your feelings, I need to feed my family so I’m sorry if you have trouble putting the sex you want on your passport I’m more worried about feeding my family’? At least in concept?

    I think that’s where a lot of that sentiment came from. The people of the nation are hurting, and part of Trump’s message always was ‘I see you hurting and I want to fix it’. Dems are totally tone deaf in their messaging. A huge % of the populace gets left out of the ‘American Dream’ and they say nothing. And in recent years they focus a lot on social justice issues and identity politics while ignoring the elephant in the room. It’s why those good people are saying fuck your feelings (IMHO at least), because if the choice is your feelings or their livelihood, then of course they’ll tell your feelings to shove off.

    Of course it didn’t work out that way- government cutbacks, tariffs, foreign policy, all handled in such a ham-fisted non-strategic way that whatever benefit might have been gained was instead lost. And now it’s the little guy suffering, so you see a lot of people renouncing their votes.

    All I’m saying is keep in mind some of those people who said ‘fuck your feelings’ thought they were fighting for a greater good. I don’t believe they turned malicious. Some did I’m sure, but not all of them.


  • This thread got me thinking a little more about Mr. Davis.

    We talk about ‘not tolerating intolerance’ but I think there’s a second level-- there’s the intolerance (the actions of the racist), and then there’s the intolerant (the racists themselves). It’s easy and simple to group the two together- we don’t want racism, we don’t want the KKK, we don’t want KKK members, all of you go fuck yourselves with your burning cross and go die in a fire (preferably in another county).

    I don’t think Mr. Davis would tolerate intolerance any more than you or I. But I think what he does is tolerate the intolerant person, engage them in conversation, treat them like a human being. And THAT can help fix intolerance- by reaching out to the intolerant people and trying to bring them into the larger community and heal them, rather than shunning them and reinforcing their stereotypes.


  • It’s BY tolerating it (or more specifically, the people who espouse it) that he fights it.

    And I think that’s the key difference- tolerating intolerance (the action), vs tolerating the intolerant (the people).

    I think we would all (probably including Mr. Davis) agree that the action of intolerance should not be tolerated. For example, if a local movie theater wants to have ‘whites only’ movie nights, that should not be tolerated and in fact we should all aggressively fight back against such things wherever they happen.

    But what of the intolerant person? What of the theater owner in the above example? Should we run him out of town? Tar and feather him? Refuse to talk to him?
    The KKK folks he encountered are used to intolerance- threats, shouting, protests, etc. They know they’re not popular, but that helps feed the belief that they are right. They’re used to it. They’re NOT used to being welcomed by anti-racists.

    And thus Mr. Davis got through to the racist- by tolerating the intolerant, not by tolerating intolerance. It’s a subtle but vital difference.



  • We used to be. The rules changed about 10 years ago.

    I’d rather have 120v wiring I can do myself than 240v wiring that I have to pay someone $hundreds just to replace a light switch.

    A lot of big appliances require higher power. Dishwashers, clothes dryers, fridges.

    Here in US dishwashers and fridges run on <1500w. A fridge should only use a few hundred watts tops unless it’s horribly inefficient. A dishwasher needs power for the heating element but ours do okay on 1500w, although yours probably heat up faster. We use a different plug for clothes dryers, usually a NEMA 10-30 or NEMA 14-30 (30A at 240v), sometimes NEMA 14-50 (50A at 240v) for really big stuff like EV chargers.
    Our power is split phase (two 120v legs, 180° out of phase, so either phase against neutral/ground is 120v, phase A against phase B is 240v). So with those plugs you either get both legs and ground or both legs plus neutral plus ground.

    Some powers tools, drill press, plainer

    Almost all US power tools run on 120v 15A.
    There’s a few really big ones, mostly designed for professional shops, that need some flavor of 240v, usually with a NEMA 6-15 outlet (like normal US outlet but pins are horizontal rather than vertical). These outlets are uncommon outside of wood shops.

    I never worry about load splitting,.

    The only time I’ve ever even considered this is a. charging my Tesla on 120v, or b. running a space heater and a hair dryer at the same time in the bathroom. :)

    Bottom line- yeah NZ system has higher power density but I don’t think the benefits outweigh the loss of ability to work on it yourself.
