About this deal
If you go for the Byron, then the sparky is likely to put the Byron transformer in to the Consumer Unit, which would mean when you switch to the Pro2 you would have to open up the consumer unit itself to switch transformers.
Your Ring Video Doorbell Pro requires a power source that supplies a minimum of 16 volts AC at ~20 volt-amps when connected directly to a transformer (supplied) or plug-in adapter. If that is the case then there's no way I'll be able to neatly get a cable from the CU to the front door.If, like most doorbells in Europe, your doorbell only works at 8-12 Volts AC, your existing transformer won't have enough power to support your Ring device, and will need to be replaced by the included 24 Volt Ring transformer. This seems to be the most future proof solution as bell wire will probably be usable by any future system while the rest of it could be switched out easily. Some mention that it does the job, looks good, and works fine with wired ring doorbell, while others say that it's too expensive and won't work.

I installed a transformer by my consumer unit that is 24v / 500mA DC, but Ring are saying this isn't correct and i need an AC transformer plus the separate power pack which i think converts from AC to DC). You could take mains supply from an existing socket, into the Ring transformer, but you would need to locate a housing for the transformer at some point in the supply to the doorbell.

Therefore using a bell transformer for continuous use determines a temperature rise of the transformer which could cause it to stop supplying power, unless the work/pause cycle allows the transformer to sufficiently cool down. It may be worth avoiding having a bellbox completely as it will not be used once you have the Ring Doorbell (+Chime).
