I've added an Open Therm GateWay to my home setup. This device is situated between the central heating and the thermostat, and it monitors the communication between those two. Ypu are then able to indert extra messages. The device I bought from Nodo Shop. It's an DIY project, and I had only to solder a few parts. I added an NodeMCU to act as an bridge from serial to WiFi.
I hooked this up, added the gateway to Domoticz and it worked.
I've removed the contact form, it was actively being misused. The builders of the Joomla module shroud themselves in silence, so I won't mention them.
I'm very happy with the results from using a Pi-hole for blocking all kinds of internet advertisements. Running on a Raspberry Pi 3 in my home network, it 
takes care of allmost all ads. It works by acting as DNS server, but it has an automatic maintained list of ad-serving domains and every request for such an domain results in a blockade. I've now got it running for more than three months.
I hardly get any feedback through the contact form, so whenever something pops up, I'm always curious. This time it's Marilyn Shaw informing me that I've got a broken link in one of my articles. And, very helpfull, she pointed me to a useful replacement.
And that's when the cautious mode kicks in, the message contains a shortened URL , and the shortened URL and the useful replacement both end up at the same domain www.whoishostingthis.com , and the email address also points there. The ip-address that's used for the posting originates from the Philippines. Searching the internet reveals more of these spams, including another message if you do not reply or change the link.
What surprises me the most is the effort that went in to sending me the message, as the contact form I've used requires you to select a picture to send the mail. There's no simple way to script this, so an actual human, in my case Marilyn, has to type that message
Message after the break
