Hi All, I finally I had a short 10 minute chat/ show and tell with my farmer friend. He decided to go with the Wireless Tag solution. I want to emphasize that I'm a light weight tech enthusiast and he's a heads down farmer with little knowledge or background in technology. Preventive maintenance is almost non existent on his farm equipment. It's a fix it on the fly - however it's possible environment!! Not a great mix for anything more than a canned plug and play technical solution needing little care & feeding.
I did a quick fly by to check out his network infrastructure in the main farmhouse. Not sure if his cable modem is DOCSIS 3?? or his WLAN Router will make the final cut. I believe the WLAN is running wide open, so password protection is high on the list. I plan to install one Ethernet Tag Manager and then configure the account, gui, parameters, alerts, etc for a couple sensors and then move them as far from Tag Manager #1. If the Tag Manager detects the sensors at the the farthest greenhouses, then we're golden and will likely use a single Tag Manager to configure/monitor all the sensors
Here's what I've come up with so far to get this off the ground.
* (2) Ethernet Tag Managers - One located at his home/farm house, the other (if necessary) located at a secondary house at the other end of the farm.
* (40) Wireless Sensor Tag Pro ALS - rainproof (includes spares and additional greenhouses not initially factored) to measure temp, humidity, and ambient light
* (1) WLAN Router - 8 port
* (2) TP-Link N300 Wi-Fi Range Extender (TL-WA855RE) - might be a cheap option if there are fringe areas (all greenhouses have AC power)
Thanks again to everyone who took the time to offer suggestions and contribute. I may provide a quick update to share progress.
Happy Holidays!!
