Yup; old home deck ran a plastic flexible PVC line for gas. It was a static connection and I did have a couple of issues with it in some 30 years of using it.
In current home ran outdoor black pipe out to a quick disconnect with shut off valve (well too in the home ingress pieces). The grill came with a flexible gas line with the other side of the quick disconnect. Its been now some 10 years and doing fine.
The HV box adjacent to the grill is just an outdoor 4X4 box (using outdoor conduit) with a weather proof cover over the switch and outlet. The overhead grill lamp is connected to the 3-way configured switch. Initially this switch was an X-10, then Insteon and now UPB. The kitchen by the window 4X4 box was just a single outlet with a single mudplate on it. I ran a new HV wire / conduit from the outside box to the first in-line box to the kitchen outlet, put in a double mudplate (PITA) with same old outlet plus another UPB switch. There is another HV coach lamp on the deck (well matches the rest of the home) with a UPB switch connected to it.
I redid a bit of the cedar trim on the deck. Initially removed the cap and put in the LV 12 guage wire along the top of the railings and replaced the cap. The LV wires are hidden. They run into the home to the multizone / DIN 12VDC powered LED section. (mutiple LV 12VDC setups for outdoor LED lighting).
PIR / CCTV / other LV wires run along another chases. Audio subzone is just using Russound outdoor speakers. They are mounted on brick. One speaker going into the home using a chase next to one kitchen speaker zone into the basement. The other on the brick wire is hidden by matching cedar deck trim. Lighting / security stuff is using multiple events driven by whatever.
I also had a water spigot installed on the deck (on the brick wall) for watering plants when doing the deck (water and gas lines installed at the same time).
The multiple chases going into the home under the deck were done before deck was completed. That said I did make a little access panel out of cedar that looks like the deck (well actually done up by the deck wood crafter / installer).
In a quickie syopsis; all of the outdoor lighting security events are switched on and off by UPB switches which are controllled by the OPII panel with outdoor security "do whats" also connected to the panel. There are no self contained non connected autonomous sensors configured (well if that makes any sense?). Now most / all CCTV is using IR LED lighting; regular lighting turns home into "daylight" during "nightime" sometimes. Lately a coyote and a cat has been triggering stuff at 3 AM.
