Can confirm, the metal spray guns are way better than the disposable cans. Their 'reusable' disposable cans had poor flow and kept clogging on me.
Wikipedia says Europe uses mainly the shorter cab-over-engine tractors in order to maximize trailer length while staying under the total length limit. They commonly pull standard ISO shipping containers, so in that case at least the difference is all in the tractor.
I see the Unistrut SLR100 solar panel clamps and they appear to be UL-listed, so that does seem like a good option . I just need to find galvanized or aluminum strut locally.
Do you have any recommendations for hardware to mount the strut to the roof?
Panel Mounting System Recommendations
Hey all,
I've got a set of three 60-cell panels and microinverters that I want to mount on an asphalt shingle roof. I'm planning to expand the array to 16 panels in time.
Does anyone have recommendations for low-cost mounting systems and online retailers that sell them? I like the idea of rails, but from what I've seen shipping costs are prohibitive and I'm trying to do this on a budget, so rail-less options are appealing also.
The storage capacity is sized for daily consumption, not the yearly figure you quoted. And of course, this is one small project out of the hundreds of plants that will be needed to meet climate goals.
The biggest issue with solar right now is that the output varies over the course of the day, leaving other power plants to take up the load at night or during cloudy weather. The attached battery storage averages out the solar plant's output, letting it be a useful contributor to the grid around the clock. There's other benefits like grid stabilization and peak shaving, where the battery stores and releases oversupply from the rest of the grid, not just the attached solar panels.
OP here, I ended up buying one USI MI106S, which advertises the following:
- Combines the benefits of both Photoelectric & Ionization technology in one alarm
- Smart Alarm Technology virtually eliminates nuisance alarms
- Automatic temperature and humidity compensation continuously adjusts to variations in environmental conditions, reducing nuisance alarms
Which sounds like what I'm looking for. I'll try some informal tests on it before I buy more.

It's a good idea, but at this point I'm too frustrated to wait a few months to see if the moved alarm does or does not go off. And then I'd have to figure out what's different and how to fix it.
Right now I'd rather spend some money and get smarter alarms, if they're available.
Multi-Criteria Fire Alarms
Hey all,
This is only tangentially related to HA, but it seems like this crowd might have answers. HA integration would be nice but is not required
We moved into a new house about 3 years ago and have been plagued by nuisance alarms ever since. They happen most often in the middle of the night, but aren't uncommon in the daytime.
I have:
- Replaced all the old hardwired detectors with new battery-only ones thinking it might be caused by EMI.
- Ruled out insects crawling into the detectors.
- Sealed the electrical boxes thinking it might be dust from the attic.
- Installed an excellent filter system in the HVAC.
- Cleaned out all of the detectors with canned air.
Other random info:
- Only the ones on the second floor go off. There are five upstairs and two downstairs.
- I'm pretty sure one (and only one) of the false alarms was caused by humidity from a shower.
- Seems like they're happening less often since I installed a new HVAC system, but that could be due to less dust or due to smaller temperature swings (less of a setback at night).
I think at this point I want to get some fancy multi-criteria alarms, ones that are specifically for reducing your nuisance alarm rate. Also for increased capability, though - one of my coworkers just narrowly escaped a housefire with his wife and dog. Their fire alarms failed to go off and he was only woken by the sound of the flames.
Any suggestions for multi-criteria alarms that work with hardwired 120VAC, preferably with hardwired interconnection?
Full-on alarms, not the low-battery chirps. I think the first incident after I replaced the old detectors happened in less than a month. They're the 10-year sealed style, anyway.
Did you replace them with alkaline or lithium 9V batteries? In my limited experience the alkaline batteries last less than a year before the low battery chirps start again. If your house is significantly cooler at night, battery voltage might drop enough to start the chirps, also.

But the pressure from the atmosphere applies to both sides of the sphincter, resulting in zero net pressure. Unless the suit actually does press against the outside of the sphincter like it does the rest of the body, I think OP's concern about the suit squeezing you like a tube of toothpaste is valid.
Maybe the suit only applies a few PSI instead of the full 14.7, which it seems like one's sphincters would be able to withstand.
FYI, there is a Scheduler card that might make that automation easier.
I've got a T6 Z-Wave also, controlling a 2-stage heat pump. I have it connected to HA through Zwave2mqtt. It's been pretty great except for two things:
A. Changing the time has no effect, as if the clock is read-only due to a hardware issue. I've had to set up the daily schedule in HA instead, but it's probably better that way anyway.
B. I can't see the stage and aux heat status in HA. Looks like all it exposes is a 'heating' or 'cooling' state. Anybody know how to get more info?
I've had 10 of the RGB ones, E21-N1EA, for a few months now and they've been working perfectly. Not the brightest or the most accurate color, but they're simple, cheap, and local-only.
Have you checked out Frigate? It's a local service that captures RTSP streams from cameras and uses neural net image recognition to trigger events / recordings. It has good integration with Home Assistant.
