Wow . . . you can see my hothouse from space . . .
The tree at the center of the hothouse is a bit under 55 feet from my desk. Presumably, the MCU controlling the heater will hang from the center tree.
Between the are the interior drywall/gypsum wall, probably the glass mirrors of the closet (but possibly the very edge of the interior wall, likely the corner of the next wall (drywall with wood frame, but I think there’smnetal at the corner), either the edge of the brick chimney or the heavy glass sliding door, and (in the winter) a 6 mil plastic sheet on the side of the hothouse.
It’s a bit under 75 feet to the two left corners, and a bit under 65 feet to the two right corners.
It looks like about 25-30 feet through an interior wall, a window, and back through the garage wall from the desk to the sprinkler mcu.
Ultimately, the left grapes will have about three controllers (maybe one if the sensor lead lengths work out) and three valves (they get different sunlight), the center grapes will have one, multiple along the back and right wall for the berries (the manifold doesn;'t currently extend that far), probably a couple along the back of the house, , and one or two each left and right of the hothouse, and in the upper right. one at each junction and terminus of the tree manifold (except the junction just outside the hotheouse, so about two dozen in the back (lead lengths to sensors and available pins will govern), and maybe a dozen in the front (it doesn’t show in this, but from where you see the lawn starting to the sidewalk has about a two foot drop, limiting watering time).
Keeping the cost of the units down will help ![and, it’s part of the challenge. AT-09 are about 1.80, while NRF are about .65, and HC-12 about $2.75. (Minis are about $1.60!).
The “eventual” valves are kind of new, and still about $5 each (latching 1/2", with a pulse that a battery powered 328p could handle), so for the next couple of years, entire manifolds will be on or off.
(How’s that for too much information ? )
