I’d like to experiment a bit with some home automation but would like a little help to get started. I’m not so concerned right now about actually controlling much, I really just want to gather data at this point, but I’m hoping I can get some advice before I go spending any money. Currently I have a Raspberry PI with Raspbian that we primarily use for media streaming. I installed Domoticz onto the PI when I got my cameras set up and have them connected, but that’s as far as I’ve gotten. What I’d like to do right now: 1) Install temperature sensors in a few locations to track the current and past temperature. - Chest freezer in my basement - Chicken coop behind the shed - Pond (I’d really like something a foot below the surface and since I’m there, maybe 10 feet below surface. This is probably a stretch though) 2) Install a switch on my mailbox so that I can get an alert whenever it is opened. 3) Install a light sensor outside (probably on the shed) to have it turn some outdoor lights on and off automatically at dusk/dawn. I’ve seen on this forum that some of you use these really cheap temperature sensors (Amazon.com: WINOMO DS18B20 Digital Thermometer Temperature Sensor IC, Pack of 10: Home Improvement) but how are they wired into your network? Would I need a Raspberry PI relatively close to each location that I needed one of these sensors? For the other sensors (light/mailbox) I think Z Wave would be my best bet. I see some Z Wave temperature sensors but at around $30 each that’s way out of my price range for the simple things I want to watch (might be worthwhile to put on in the chest freezer though). From what I have read I will need some sort of controller to connect my devices (multiple temperature sensors, mailbox sensor, ect) to my network so that Domotocz can listen to them and alert me. What I think will work for me would be the Aeon Labs Z Wave USB Stick ( Amazon.com: Aeotec by Aeon Labs ZW090 Z Stick, Small, White: Home Improvement ). It’s only $45 and I could plug it into my PI which is roughly in the middle of my house on the 1st floor or in my router which is on the second floor, just above the PI. My concern is that the Aeon USB stick says it has a range of 100ft which will not be nearly enough to reach all of the buildings on my property. My biggest question right now is, how do I get all these devices connected to my network so that Domoticz can listen to them? Will I need a 2nd and 3rd PI and Aeon USB stick at each location (shed and barn) and just hope that the one in the house can see the sensor at the mailbox 150ft away? I have network access in the shed and barn so that helps. I feel like I have an idea of what I want to do, but it just isn’t quite clicking on exactly what I need to do to get there. Any help pointing me in the right direction would be appreciated! I'm pretty good at making things work for me if I know what im trying to do is possible in the first place. Does what I'm trying to do seem possible? Reasonable?
