Sorry, hadnt seen this post yet.
I completely switched from X10 -> Z-Wave a few months ago:
Primary Controller: ZTH-200
Secondary Controller: ZCU201 USB adapter
5x ZDW230 Build-in Dimmer Switch
And 2x Qees Power
I still want to buy some DANFOSS RA-PLUS for the Heating part, i've only read good things about them.
First you set up all the devices you want to include in your network (you have to use a primary controller for this)
Then you transfer all that info to the secondary controller (PC USB / Serial interface)
(this will also include the devices into Housebot)
The last step is to pair all the devices with the PC interface so that when you switch / dim a device with the local buttons, Housebot will be notified of the change immediately.
The only 'problem' I seem to have with the zwave interface is when I shut down Housebot, the process will hang for minutes, but as soon as I unplug the Zwave interface, Housebot can shut down immediately. Since I dont shut down housebot that often, I dont mind this.
For the door lock you can go 2 ways I guess:
1) Go for a complete lock with automation capabilities (pretty expensive) :

2) Take a universal door opener that works on 12V, and use a Z-Wave Qees Power switch for switching it when needed.
On the irragation part I cant help you since I dont have a garden to automate
