We are asking to cover 400 meters in line under greenhouse, Wifi works in some everoinments but as soon temperature go under 10ºC celsius coverage go down and connection is not enough. I decided to connect each Wemos to ethernet to get a good connection.
I found ethernet cable at 11 cents of euro a roll of 305 meter .
Of course test is at home and my suspect is wrong pins selection.
I still don’t get it. How are you connecting things? Can you make a little drawing or something? I’ve got a feeling we are missing something in your story.
Then skip the Wemos and use an Arduino. Otherwise I think you will be looking at more trouble then just pinouts. I don’t think you can completely disable all WiFi processes on an ESP based device and might end up with all sorts of conflicts.
Regardless, what you are asking to do is not Blynk related, so not sure how much assistance will be available… but I guess we will see
I have peppers and I must control Humidity and temperature I also use Tensiometers of irrometer plus I am making an alarm System across all the greenhouse.
That’s a bit over the top. You can do with a switch every 90 or 100 meters. Good ethernet cable is certified for up to 100 meters.
And than, I assume you will have a bunch of stuff on a Arduino or other MCU controlling the Greenhouse things. That Arduino or other MCU will connect, apparently, with ethernet to your main internet connection, right? In that case you will need an Arduino to connect to the Ethernet network, not a Wemos. Unless you plan on putting up an Accesspoint in the Greenhouse and connect the Wemos to there with Wifi (which would probably a good idea).
Having worked on many long distance 1-10+Km WiFi setups that ran all year long (we get -30C around here)… Just get a good WiFi repeater and/or directional antennas (if the Wemos accept external antenna).
Not everything you read on the internet is true… Besides, I manage an Enterprise network with over 15.000 ethernet ports, so I know what I’m talking about.
Ring topology can’t be done with Ethernet because it’s a bus. You would create a loop.
Anyway, I think you have to rethink your design and consider the Accesspoint in the greenhouse scenario. I think that would be a great idea. You could attach a bunch of Wemos’ devices wireless. There is no way to connect those to the ethernet. You would need Arduino’s with ethernet ports for that.
Also, if you plan on covering more than 100meters I’d highly recommend using fiber optics instead of ethernet. For one, if lightning strikes, you don’t want the ethernet cable to transport that energy to your house network and blow everything to smithereens
Step1: create a drawing of what you want instead of just trying to explain it. You’ll gain good insight and we will be able to help you much better.
1.-Nano station loco m2 with internet (home) to another nanostation loco m2 (500 meter good signal on top green house)
2.- Nano station loco m2 to a switch …need to cover a lot of meter
I have an access point in the greenshouse on top but it is not realiable after you go so long. This is the real situation. Circles are sensors or Switch that should be put.
But you cannot use the W5100 with a Wemos. You need an Arduino for that. Or maybe it can be done, but there is no need for it. Why would you want a wireless board and connect it to ethernet?
With a lot of hassle you probably could connect the board to it physically, but chances are you cannot load the UIP library into it because that’s not made for a Wifi MCU.
Anway, did you try? You could try an ENC28J60 ethernet interface. That is just SPI and should work, but I still have my doubts about the library. I think it will not work.
A Lamborghini is more powerful than a dune buggy, but you don’t put mudders on it and play in the dirt
If you must run cable from your router location to the greenhouse or centralized location for the Wemos devices, then simply use the cabling to go to the access point, then from there to the WiFi devices. Even a mesh network would be better than hacking ethernet into Wemos.
