If you are considering using the probe remotely http://www.sheepwalkelectronics.co.uk/index.php?cPath=23 have some hardware for using RJ45 plugs/sockets (and CAT5) cable to make connection plug/play AND you can connect multiple probes in parallel (because of the ‘one-wire’ bus) if this is helpful. You would need software modification to the standard probe library for probe addressing but this has {obviously} been done before. Also you might find additional information on the emoncms site http://www.sheepwalkelectronics.co.uk/index.php?cPath=23.
For a really simple display solution you could consider Node-Red Dashboard (which is pre-installed on a Raspberry Pi) and a cheap tablet such as an Amazon Fire using the browser only. There is quite a lot of information around about using Node-Red for control activities (timers and temperature control) that have graphical interfaces as well as displays for weather data http://tech.scargill.net/ is worth a read.
Finally MQTT is becoming the backbone as a data repository and for data exchange. The HA interface isn’t what I would call ‘plug and play’ but the Node-Red one is (because of the GUI and no YAML). SQL is also being used with Node-Red as a database to store configuration data and to drive some repetitive operations. I’m working on a Device Tracker (based on Ping) where the device IP address are held in a SQL file.
