HS3 in a van?

LOL!

Since there won’t be any 120vac, what could be used to dim 12vdc LEDs?

Any ideas for a/d converters to display holding tank levels?

Use these:

Supply side hooked to your 12V rail, output side powering your LEDs. They come in a variety of constant current levels, 300mA, 350mA 1000mA etc.

Then you connect the PWM wire to a PWM output pin of an Arduino, and control it with either Michael or Greigs plugin.

This is how I'm doing the lighting in my home now. I use the LDD-H board mount variants supplied by a 48V DC PSU, powering BridgeLux Vero 10 COBs in the downlights. Concept is exactly the same just with different voltages.

Edit:

Alternatively, the Qubino RGBW Z-Wave module can be configured to control 4 x 12/24V lights independently. And it only requires a 12/24 VDC supply.

All the ones I've dealt with in RV/Marine applications wind up having problems. It's usually debri gets caught on the float or capacitive sensor. And, it doesn't take long for operators to just give up on them. If I were to build my own RV, I would probably try using an ultrasonic sensor with an Aurdino. The same kind of thing can control LED's, btw. But, I don't know how comfortable you are making your own kit. I get it if you would prefer an off the shelf option.

I use SeeLevel gauges in my Airstream. It’s an ultrasonic transmitter into the tank. Avoids those issues. But I’d like something I could read with HS3.

One thing to consider is your battery usage. Sending sensors and such over radio waves will use more power then wired. I would consider wiring as much as possible.

There are a few DC powered LED dimmers on the market. I would use a buck/boost converter, voltage regulation, etc.

have a look at MQTT and the Tasmota stuff, i bet you could do nearly all of what you want using that.

I can almost hear Chris Farley saying, "I've got Z-Wave in a van, down by the river!"

Haven't watched that clip in a while. Made my day.

Um, why not just use a Zee S2?

Built on a Rasberry Pi, which is powered by 5V I believe. Then use a buck converter to supply 5V from your 12V rail?

i have installed one of these when i had a pc in my car like then year ago https://www.mo-co-so.com/Intelligent...ies-s/1867.htm

I have noticed that new class B RV’s have touch screen systems that control lighting (including 12vdc dimming, tank monitors, generator controls, etc.

I’m looking into buying a cargo van and unfitting it myself to a RV. I would like to incorporate a touch screen system and, of course, I thought of HS3 with fire tablets.

Is is there a low power 12vdc PC that would work? Can I use my home license?

Is there a better system for this already built at hobbyist pricing?
