Do not blow this up to the sky.
I already have WiFi 1 meter away from Neuron, so no expenses for that.
At us is like that if anything wil be burned, that the overcurrent will come over PHONE LINE, electricity is NOT the problem anymore, we solved that out few years ago, and now is not the issue anymore.
If i put the surge protector(belive me i tryed that) it is blown too and i have two expenses, surge protector and router, if i use only wifi i only change router and that's it.
But this router is "blown-burned" only if nobody is home, that happends werry rearly, but it happends, if anybody is home all you need to do is unplug the DSL line and NO problems at alll.
What about that WiFi connection is not so 100% like wired is ordinarry BS, before Neuron i made automation by myself and it was runing wirelesly for 3 YEARS with any problem at all, it was not burned by lightning, line was woking 24/7 and i NEVER had wireless connection problem at all, so that is why i want to connect Neuron wirelesly, i could use eg. wireless extender if there was a problem and put between extender and Neuron a UTP wire, and let between extender and router be a wireless connection, that would be even better than the RPI3 onboard wireless.
But i can go on but i think i explained why i need wifi connecton.
PS. All power for mixing walves, pumps and Neuron itself, are connected over 2kW UPS (i know that is an overkill), that anything make and come trough all pover protection for the house, will rather destroy the UPS before all other things that are connected to UPS, at least i hope so.
