I read the code for the Arduino, as well as the Python code for the Raspberry Pi, and it looks like they're using pubnub.com as an MQTT-like service. Basically a middle man between your IoT device and your computer, so it makes sense that they're using it.
If you didn't want to use pubnub, you could potentially have the device send an update to your website using a format similar to how weather underground does it. For example, yoursite.com/lightningupdate.php?lightningcount=<lightning counter>&lightningtimestamp=<lightning timestamp>&more-variables-here. The PHP file could submit that data to your database so your website can pull it from the database when a visitor loads your site. Something along those lines. I think your device is using an ESP8266 for its WiFi connectivity, so you could replace the pubnub stuff with an HTTP GET method from the ESP library. In your code, the section publishPubNubMessage is where they are publishing it to pubnub. You could instead format the message variable and format it like mentioned above. Then you need to do the HTTP GET. Maybe something along the lines of this <https://techtutorialsx.com/2016/07/17/esp8266-http-get-requests/>? The bits where you see http.begin(); and http.GET(); You could also keep the pubnub and add the HTTP GET portions to have it send the data in parallel. This does sound perfect for weewx though since it already uses a database and you can extend the the database for all these fields. The only challenge would be ingesting that data since you're already using a driver. I've never created a service, but I think a service can bind to the loop so it can input to the database much like a driver. So maybe a combination of many things could make this work for weewx? 1) Create a new service which runs an http server that can accept data from HTTP GET and submit to the loop. (Think a hybrid of the interceptor driver and the maxbotix service) 2) Re-program your arduino to use the http get as above and program it to submit to your weewx server instead of your web server 3) Figure out what variables you want to keep and how often you want to archive them and use those in the GET. Then update the service so it's aware of these variable names to submit. 4) Extend the weewx database schema for the variable data you want to save. 5) Update your weewx skin, or your website, to get this data from the database. This is all speculation though since I don't own the hardware, but that's a couple potential workaround to get away from pubnub and still being able to get the data into a database.
