Today the water pressure in my central heating did this.... a drop from 1.8 to 0.7....and I got a nice email warning from Domoticz as configured.
So I could spend the afternoon to find the leak and fix it, instead of ending up in a cold house. Thank you !!

With second hand OpenTherm Gateway (OTGW) in between my thermostat and boiler.

Nice. In the ages before domoticz I always noted the meter values for gas and electricity, combined with degrees days. One time I noted a deviation and checked out the boiler. The culprit turned out to be a locked flow switch. This kept turning the boiler on and off because max temperature is reached. I cleaned the switch and everything was fine afterwards.

One of the most useful features I have installed in Domoticz: an e-mail alert when the water pressure in my central heating becomes too low.
After filling up the system last week, I got an alert this morning. Turns out the pressure dropped from 1.8 to 1.0 in 2 days.....leak has now been fixed.
The spikes at the end of the graph is me filling up the system, locating the leak and fixing it.
