I used to run the Davis Instruments, now Texas Weather Instruments 1Wire systems. There was no real progression to Web/App/Reality with the devices so I abandoned them (have like 5 systems with full setups)
I moved to the Acu-Rite 5-n-1 with the Acu-Link internet bridge because it is low cost. By that, I mean you can catch them on sale for ~120, with the minimal lcd display for inside the house. You can add on up to 3 other sensors for temp/humidity (inside, celler, wine, humidor, etc).
The app is showing it’s age, but works. The device does do rapid-fire to wUnderground.
Wunderground was one of my requirements.
It is like 400mhz wireless, runs on 4 double A’s and my batteries last over a year in the unit.
When I said, if you find a deal, they have 20% off for the Memorial Day Weekend, so that 20% comes a few times a year.
The Pro 5-n-1:

Has Windspeed, direction, temp, humidity, rain, Solar cell to run a fan, that draws air across the humidity to get a better sample. All in a single pole mount unit.
The only thing I’d like over and above that, is have one of the solar cells charge some l-ion, or even nm-h batteries so I never had to change them.
I intended to look at building a circuit, since it would be small and would work off of one solar cell on the pro version (has two cells for the fan)
I see one post on here about aculink, so assume someone has gotten this data driven to openhab, but can’t find anything else.
Love input, hope what I said helps.
