My mate Angie (she's lovely) has a pub (and that's why she needs to remain my mate).
She has two letting rooms in an annex. The heating system for these two rooms can (and will) be made independant of the rest of the building. The proposal is to install two SonOff TH10 wi-fi switches to allow her to remotely 'enable' the heating. Each room, once enabled, will have independant temperature control under the control of the user via a simple domestic dial thermostat. That's simple to achieve.
The wi-fi signal at that end of the building is dreadful and unreliable, so she wants to improve wi-fi for the room users too. Here the proposal is to run an ethernet cable (easily) through the cellar from the office router to a new router near to the rooms, thus providing a new wi-fi address for the users and for the SonOffs.
My question is simple: Is this use of a CAT5 cable to link two routers a sensble way to achieve her needs, and will the letting rooms have a different SSID to the main office? In doing this will the password protected security of the office network be compromised by having another network (with a freely given password) wired into it?
My second question is a little more complex: The TH10 uses a DS18B20 digital temperature sensor. I want to run a (longer than standard) cable from the SonOff jack socket to a wall mounted enclosure (one in each room). What measurements of the electrical characteristics of the standard sensor (terminating in a jack plug, and therefore being measured at that jack plug) can I make to determine which jack connection is Vss, which is Vdd, and which is data (short of hacking into the SonOff or chopping up the std sensor)? ie non destructive determination of the pin-out of a DS18B20.
PS the SonOff does not read the sensor's digital address, as it only has one sensor per TH10.
For those who want to know more, the temperature measured will be used to limit the let room's temperature to above 15C and below 23C, or whatever temps she decides.
