We're still on the dock leaf technology here!

I work off farm as a consultant with a cloud software vender but I'm focused more on the front end configuring with the customer rather than the back end tech.

One idea I've been play with is an online platform that is all based around the map for the farm. On it would be able to see all your animals using gps/geofensing on animals with alerts if they leave the paddock. Monitor the water usage through flow sensors in the water pipes to monitor flow and potential leaks, also have IOT values to turn off water so if you input that the animals will leave the paddock today at 4pm, at 2pm the vale would switch off to ensure the trough empties. When the GPS on the animals detect the animals enter a new paddock it would turn on the water.

Most useful part of all I think though would be something simular to what someone posted earlier where it lifted wire using a a little motor. On the out farm we have cattle, we could setup a timers to lift the wire at a particular time to give them more grass and use the Geofencing to confirm they have all moved to the next paddock before lowering it again. Pair all this up then with a little drone. You mark on the map which field you want the drone to go to and it would set off on a preconfigured route taking the stress out of flying a drone allowing you to focus on the camara output

All of this sounds great but I suppose the amount of value/time it would safe would be minimal

Came across the same 800 metre limitation when reading up on it last night. From what I read, the tech to measure accurately enough isn't currently out there except for possibly in the US military

Id like to extend my wifi network to the back of the house as my router signal can be spotty because of the stone dividing walls.
I have tried wifi network adaptors which do work, but give me like an 80% reduction in speed compared to being connected to the router regardless of where I plug it in. Also I would prefer one wifi network as opposed to having 2.
I have an old cat5 cable running from my router to the back of the house which im sure is good.

My existing router is a generic one, local line of sight provider, getting 40mbps on a good day. Im not sure if its security is set to default but I can probably get details if I had to.

Im wondering if I can buy another router, connect it to the first via the cat5, configure and have a seamless network back and front?

Might this do?

Ok whippersnappers who do all this tinkering.

I’ve no broadband on the farm, for the moment.

But I want to have WiFi switches for lights.

Does anyone know if I use a regular router will I be able to have WiFi switches operated from my phone without being internet connected ?

I could temporarily hotspot of my phone to do the setup but it would need to work with no internet afterwards.
