I know I'm not the only one out there with a ton of square pegs and a variety of round holes to try to fit.
My current challenge is mountaintop sites that almost but don't fit small standby generators like this
At 8000 watts it is overkill on the 100 or 200 watt loads that I run, at 5 pounds of fuel per hour at (near) idle you get almost a day out of a 100 pound tank. Is wasting a bit of fuel a huge problem ? No, but delivering it would be painful or expensive or both.
Plan B is to have a good battery bank and heavy charger(s) to bank power from the generator. By pushing its duty cycle down to 1 hour in 10 I could get 8 (!) days of runtime out of a single 100 pound tank.
But now I need some way to trick it into running when I want it to. The Champion unit above has no network connectivity and apparently tightly integrated control modules which would make much harder to replace a switch with something remote operable.
Another nice one is this
which has some network (LAN !) control but still is outside its "normal" operation to start/stop on demand, I think.
I do not want to butcher up a portable generator, I have done this, it works, and if there is ever a fire the insurance companies would howl with laughter, its picture would appear on bulletin boards and be circulated as a cautionary tale.
So I ask, what have you got that is :

Genmon will work with the newer-generation Generac units, at least. We have an 8kw at at tower site. I don't deal with it as much as others, but he's got it where it's sending alert emails on status chagnes and I can remote start/stop the unit via HTTPS.

@ryanmsweeeeeeEEEEEEEeeeeet no need to reinvent the wheel I'd mark your answer as the solution, but I'm hoping for even more feedback.

Genmon will talk to the proprietary Generac autostart? Cool.
Last time I looked into this (January 2017), the small Kohler home backup model still had two-wire autostart. That makes it really simple -- just close a contact and let 'er rip.
If you want to add autostart to a basic electric-start genny, this will get the job done for under $200.

I am a big Honda generator fan. If only they would make the 1000 and 2000-Watt models electric start they would be perfect. For safety of not storing (or aged) gas I have converted to propane 2 Honda 2000s that can be paralleled. I could have sourced out all the individual parts, but or a little extra I just got 2 of this kit. https://www.ebay.com/itm/IMPCO-TRI-FUEL-CONVERSION-KIT-HONDA-GENERATOR-HONDA-EU2000IS-INVERTER-NATUR...
After some fine tuning the generator after sitting for 6 months will start on 1 pull!
Find an electric start kit for either the 1000s or 2000s for the perfect size generator for a WISP and we will beat path to that door.

We're in dire need of a generator that only needs to supply about 100 watts for just a few days in the winter.
And it needs remote start capability and it needs to run off a portable propane tank.
About 32 volt DC out would be nice instead of 110 VAC - no need for regulation , a charge controller would handle that.
Even more than that we'd like reasonably priced fuel cells that would preferable run off a propane tank and provide even just 50 watts to charge a 24 volt battery bank.
This is just to handle the load over a few times during the winter at remote solar powered relay sites.

I'd love to see a small (probably more like 200-500W) fuel cell option. An adjustable DC output capable of charging both 24V and 48V battery packs (20-60VDC?) would broaden the market quite a bit. I could live with LPG, methanol, or even hydrogen as a fuel source as long as the price & performance were right.

Problem is they are very expensive - and not at all a mature technology - there's a place online called the Fuel Cell Store which is full of components and test cells for doing R&D, but nothing commercial to buy that I see. Great tech, but you're just a bit to early unless you want to be on the bleeding edge with it...
