Thanks for the quick reply – I am learning this all quite quickly and quite enjoying it. I wasnt concerned with the $$ (I think it cost me $10 for the ESP8266), just thought it would be one less component in the mix, but if its going to be quicker and easier to use a second esp8266 then I will just go ahead and purchase one. The specific item I purchased is this one: http://www.ebay.com.au/itm/272580283375 – do you see any reason this wouldnt work? I have successfully upgraded to firmware 0.96, configured it onto my network and started a tiny web server on it to test the unit works and it seems fine. Obviously I havent even looked at the pin config as yet, so if you can see why it wouldnt work I would appreciate it. If you confirm its ok, then I will grab another one the same, or if you can recommend a better one then I will go for that.
Cheers,
RaoulHi Paolo,
My hardware arrived today finally so I am going to start working on this shortly. I was wondering if it would be possible to change it a little so that the Ultrasonic Sensor is run from the Raspberry Pi direct (which is running opensprinkler) and just use a single ESP2688 at the remote end. Given I am only doing a maximum of 12 zones from the raspberry pi for sprinkler operations (likely only 2-3 in the next couple of years), there should be sufficient pins left to physically hook everything up. Basically just trying to reduce the number of components required at the end of the day if possible.
I tried connecting to Arduino IDE 1.8.2 and have been having a few issues getting it to do anything, so I downloaded ESP8266 LuaLoader 0.91 and flashed the firmware and have been able to get it connected to my wifi and respond to commands straight away. I am incredibly new to this and learning as I go so any guidance you can provide on what I am doing wrong / what I might be missing for Arduino IDE to not be working?
What are your thoughts on connecting the sensor directly to the Pi, and if you think it will work, are you able to assist me with the code required and how to integrate it with the proposed system, including the code for the remote receiver (ESP8266) that is responsible for turning the remote pump on and off.
Cheers,
RaoulHi Paolo,
Thanks so much for your quick reply. Your attachment is spot on. Both water tanks are already within wifi range of each other (and more importantly the router). I can absolutely install sensor 1 in top of tank 1 and 2. I am not sure as to whether to use an electronic sensor for tank 2 or a manual float valve to stop the well pump from filling it at this stage as either should work fine. If you could assist with the schematics and component list and SW would be awesome.Thanks again,
RaoulHi Paolo,
This is exactly what I have been looking for. I am about to setup a Raspberry Pi running Opensprinkler to manage 12 different watering zones. The watering system is fed from a header tank that is filled but water runoff from a shed and we have recently added a line to fill it from another tank that is @ 700 feet away that is in turn, filled by a well. I want to pump from the remote tank up to the header tank for the watering system. I need to be able to have the remote pump turned on and off based on the water level of the header tank. (your example 1 scenario). I checked out the wiki but couldn’t see any detailed notes on how you set this up. Any assistance you could provide including details of hardware used would be greatly appreciated.
