electronic design

We need an IP connectivity module with integral webserver. Something akin to basic IoT home automation (but for a different purpose). It needs to accept a number of electronic inputs, probably at least 6 analogue inputs or maybe 8 analogue inputs plus a few logic inputs) and make the associated values available over the internet via secure connection. We also need display of selected values of those inputs on a web page accessed via internet so it needs a webserver preferably with https. Ideally (depending on any additional cost) there may need to be nonlinear (ax squared plus bx plus c) scaling of the values from the ADC output to some real world parameter such as Watts. There may need to be scaling calibrations on the web page which are not directly related to the ADC output. Also a settable visual indication of a 'normal' value for each parameter. Whether this is all text or graphical on the web interface can be discussed and may depend on cost. Text is the minimum of course and 8 bit resolution should be fine. Simple bargraph graphical display of analogue inputs is desirable but not essential. It also needs to have two or three relay outputs that can have their state changed via command from the same webpage. It needs to be based on well supported, widely available, low cost silicon with a good chance of it being available for a long time. Ideally PIC or similar. We absolutely will need source code, preferably in C or similar. If the designer has good familiarity with IP security considerations that would be a big plus. It is not a very high security application, but on the other hand we don't want our units getting hacked! There must be lots of boards like this already designed that could be modified to fit our needs exactly. If PCB design can be included (ideally in EasyPC) that would be perfect but we can have that done as a separate contract if preferred. Budget is just indicative, could be more or less, the market will decide. We won't go for cheap but will go for good value for money.
