I’m new to this forum, but know the value of having many ideas, and heads providing feedback and knowledge to a project.
My situation is that on the farm we have multiple water tanks and would like to set up water pressure sensors at each of them (7) 2 stations have 2 tanks next to each other while the others are stand-alone tanks.
Additionally, we would like to monitor our water usage using flow meters to gauge how much water is being used at any one time, if there are any leaks or breaks in the irrigation lines, are running too many outlets for the water being delivered through the pipes (night time we gravity feed, sunlight time our water lines are pressurized from our dam’s solar pump delivering water both to the irrigation network and to top-up the gravity feed tank that has a mechanical min/max float valve inside).
Some of these flow meters are sited at solenoid valve stations or next to tanks which we plan to monitor.
Recently I’ve installed a Home Assistant Server to monitor the solar controller to collect data, and provide feedback on how much power we are harvesting from our roof panels and plan to continue to build upon this later after water monitoring and control is taken care of.
I have some LoRa / LoRaWan equipment that I’m trying to integrate with Home Assistant (HA), and anticipate that will be the appropriate method of our devices spread out on the property in conjunction with using MQTT protocol.
I’ve got a few Arduino boards ie. D1 Mini’s, 8266, Mega, Uno and recently purchased an a Gravity throw-in type liquid level transmitter (KIT0139) to test with, plus an ESP32 board due to its extra capabilities including deep sleep between actions, and have some LoRa Hats too,
I can do the basics when it comes to programing (a long time since my Uni days), that is why I’m going to be offloading much of the logic to HA. So really just need to connect and forward data.
The bind that I am in is the hardware at present. In the past, I have purchased gear that basically sat on the shelf because it didn’t result in doing the job that needed to be done.
Over this coming month, I’m hoping to get 1 tank monitor going and relaying it back to a LoRaWan AP then directing the MQTT data to the HA Server’s MQTT Server before finally displaying it there.
Has anyone else worked/completed anything similar, I am hopeful I can learn from you to build my project and hopefully through my journey help others.
