So, last time we worked out how communications were encrypted and managed to read the current status of the heating system (whether the boiler is on or not, the current temperature, and so on). That’s great – but it’d be even better if we could actually control the thermostat from Python: set the temperature, change […]
In the previous part we had established that the Worcester Wave thermostat app communicates with a remote server (run by Worcester Bosch) using the XMPP protocol, with TLS encryption. However, because of the encryption we haven’t yet managed to see the actual content of any of these messages! To decrypt the messages we need to do […]
When we bought a new boiler last year, we decided to install a ‘smart thermostat’. There are a wide range available these days, including the Google Nest, the Hive (from British Gas), and the Worcester Bosch ‘Wave’. As we had a Worcester Bosch boiler we got the Wave – and it wasn’t much more expensive […]
At the end of my last post I left you with a taster of what Part 2 would provide: a way of producing automatically-updating graphs of power usage over time. Part 1 was based purely on Python code that would run on any system (Windows, Linux or OS X) but this part will require a […]
After borrowing a CurrentCost electricity usage meter from my local library (if you’re in the area, then Eastleigh library will loan you one for free!), I decided to buy one, as I’d found it very useful in trying to reduce my electricity usage. The benefit of buying one as opposed to borrowing one was that […]
