I went through various stages of this myself and got an Sonoff RF Bridge, that allowed me to capture and replay RF via Home Assistant. In the end though, it was always easier to use an off the shelf solution, especially for boilers. OpenTherm with Tado worked perfectly.

For the most part, yes.

You can easily verify by simply logging all data in/out of your network that the monitor is connected to and seeing if there is any unexpected traffic etc.

Some manufacturers are known to have added backdoors or methods to access data on remote devices but the internet community love tearing things apart, dumping firmware etc to see how things work and someone ends finding it in the end.

Not that it's the correct way of thinking, but if you have anything actually worth capturing in that respect and you believe you're being watched, you'd need to findn alternative ways to access it.

Commonly it's because emails are not being sent from mycompanydomain's own SMTP server and via the service provider's own.

When setting up the service, account owners are required to setup DNS records that authorise the service providers SMTP server to send on behalf of mycompanydomain so that the emails don't get rejected or end up in the spam folder.

If setup properly, they'll follow what Recaptcha done in the early days and use multiple sources and use the common answer rather than relying on a single source.

The only issues is that if people know this, they could simply flood the internet etc with fake information and if used, it could skew the results.

Recaptcha suffered from this in the early days when people found the first word was the control (known) word and the second was the word they wanted to convert to text.

People then started putting the same offensive word in for the second word, which was accepted and is likely to have affected the results.

I joined a company to help modernise it as the stack was based upon ColdFusion and they struggled to find/retain developers to maintain it.

The previous developers done a great job of documenting and structuring the system in a way that made it easy for me to migrate it onto something maintainable.

If there was enough developers floating around to make it viable to maintain in ColdFusion it would still be going now and doing a great job too!
