#Opensprinkler to home automation full
Go for the most rigid, largest diameter (up to the full diameter of the valve opening or supply) you can justify. If you drop a lot of pressure in the hose, it won't ever get to the drip system. If you do use hose, sleeve it or shade it to protect from UV. Garden hose will bake, delaminate, and leak. If you have plumbing that goes from the manifold to where your drip irrigation begins, use either heavy duty hose, or regular plumbing. Don't try to integrate that into the zone valves, those die every so often when the diaphragm dries out or ruptures, so don't bond them solidly in. If you need metering, or mixing, say if you want to mix in a fertilizer, do that either up-stream of the zones, so that it's done once for the manifold, or downstream of them, if you only want one or two, or if you have very specific needs. Your controller will output the right voltages for that without thinking most of the time. Most valves will be on/off solenoid valves, usually 24VAC (at least state side). Consider putting a union after it, if the supply is in an annoying spot to shut off, so that if you do have issues with the manifold, the entire downstream section can be swapped.
#Opensprinkler to home automation manual
If you're going to have some seasonal zones, say, misting for high summer, put a manual ball valve in for those, and another between your initial supply in, and branched section of the manifold, unless your supply tap is easily in reach. I usually just use schedule 80 PVC and a bunch of tees, with schedule 40 threads going to the valves, so that if it freezes those pop, rather than the rest of it. You need a manifold that can take enough valves.
I’m somewhat flexible with costs (within reason) and really want something that just works reliably without too much difficulty. Does anyone already use any of these with Home Assistant, and can recommend (or not) any of these particular brand controllers? Any gotchas or problems I should be looking out for? I expect 4 zones like this would be best due to (lack of) water pressure, so that I can separate and time each zone/water line to run in sequence rather than parallel.ĭoes this sound correct for the plumbing side of things? Or should I be doing something different? Any suggestions for brands/models of equipment, especially the manifold and solenoid valves? I guess I should probably try and buy a combination set of manifold and valves.įor the controller, Home Assistant has direct integrations for 5 brands listed here Hunter, Melnor, Rachio, Rain Bird, RainMachine. If I understand things correctly, I’m thinking I’ll need a 4 zone smart controller, a water pipe manifold going from the tap to 4x solenoid valves wired to each zone of the controller, a container box for the valves, 4x drip line hoses with enough water emitters for all the plants. The water pressure from the tap is not great at the moment, but I’m trying to get that improved with building maintenance people. The beds and pots contain quite a mixture of various plants, flowers and trees. Below is a simple diagram of the terrace I have a garden bed at each end and 10 or so pots running along each edge.
On the terrace is a water tap, several power outlets, and cabled/wireless network connectivity. I live on the top floor of a low condo/apartment building and above I have a pretty good size private rooftop terrace (so this irrigation is not for a large lawn/in ground system). Every day is really hot and humid all year round, and usually everything gets sunbaked on most days. This is the first time I’ve attempted to build an irrigation system so it’s a case of learning as I go, hopefully you guys can help me with some suggestions to make it work nicely And I want it to be managed using a smart controller that will be integrated into Home Assistant which is my home automation platform. So I’m needing to build a plant irrigation system for where I live.
