Hikvision won't sell to you anyway, then. With the exception of the low-end stuff, it's all now trade only. Wasn't a popular decision by them (and, to be fair, plenty of non-professional installers can still get their hands on the kit if they really want), but as far as I know it still stands...

Stock is tricky, but try here: https://shop.pimoroni.com/products/raspberry-pi-4-essentials-kit?variant=39850460086355 They have a bundle that's in stock, not too insanely priced and includes a (good quality) power supply and SD card (even with an SSD you need this to boot from). I've used this...

Good call on both of these. I used to use a fan (controlled by HA :) ) but swapped to this case which reduced temperature by 30C and resolved some stability issues I was seeing. You can get high-endurance SD cards now (commonly used in dashcams), but I've also swapped to an SSD (one I had lying...

I would certainly say an RPi 4 with 4GB - you can definitely run with less, but my experience with HA is that you'll soon be adding more and more components to it and will probably regret not getting more RAM (it's only £10 difference). One challenge is that RPi4s are quite tricky to get hold of...

To echo @secureiam , I use Home Assistant extensively with my Elite panel (integration add-on thread here: https://community.home-assistant.io/t/texecom2mqtt-texecom-alarm-panel-and-mqtt-integration-with-ha-support/219354) and it's absolutely bomb proof. I've even recently decommissioned my old...

Yup, agreed. You're thinking of TV-style pictures, where the crimewatch suspect stands passport-photo style in front of the camera, but this just isn't realistic in CCTV. Cameras have to cover a wider area from further away and if you want intruders to be more than a vague smear on the screen...

Yes, indeed, you are quite right: If you have a 2G device and your SIM does initially connect to the SMARTY network, this will only be temporary. Our systems will detect this pretty quickly and your device will soon stop working. Will have a look into some other options over the weekend.

I can get a Smarty contract sim for £4.50/mo, so the price of something specific isn't so different (e.g. https://www.quicksafe.co.uk/sim-for-alarm-systems-c32/alarm-system-sim-with-preloaded-credit-p57). Looks like there's not a whole lot of proper, bargain-basement PAYG sims available these...

Thanks gents, much appreciated. I will do so and have a read of the documentation. Downside of this is that I suspect it will only notify through Texecom Cloud and their app, which is not what I want. Not sure if it can just send SMS / call direct, but I suspect not. I could replace my...

I have a 20 year old Honeywell PSTN dialler that was a carry-over from my old alarm and is now running on a Texecom Premier Elite (driven from IOs), but as we move to FTTP, it's occurred to me that the PSTN line will vanish, and I will need a new solution to replace this. I already have...

From the documentation I've been using, it says to put it at the switch end, while it would make definitely more sense to get it closer to the lock. As it happens, it's a moot point as the lock has a 6ft captive cable, so the closest you can get it is at the end of this bit of wire, which I've...

I forgot to mention this one - the door lock (which came with the least useful instructions every seen!) came with a mysterious small blue electrical component. However, a bit of Googling found this page which not only explained what the impact of back EMF is with magnetic door locks, but also...

Thanks, very useful. Will have a play later this week when the rest of the family are out and I can play with full sets without annoying anyone. For now, I just have the output working and can at least monitor the gate status through the appropriate zone (even if it plays no part in the alarm)...

This does make sense - the documentation doesn't make it clear that the when using Force Omit that the zone only remains omitted until it's secure, at which point it becomes a guard zone again. What I'm trying to achieve is something like this: As you can see, the gate zone will never report...

Thanks for this. Reading the docs suggests that this will actually omit the zone if it's not secure when the alarm arms, so I don't think this will do what I need. What I think I might do is common two (active low) outputs together, which should allow me to say "output active if in exit OR...

All installed and working. In the end, I decided against using a dedicated PSU and went with my original plan of running it directly from the expander PSU (after all, this was one of the reasons I went for an expander-with-PSU in the first place, rather than using an un-powered expansion...

I'll be honest - I was mostly being lazy :-) I've ordered a power supply and will do it the correct way. Thanks for the advice as always!

Thanks all. To explain my slight reticence here - adding the magnetic lock to the existing system would only cost me about £50 for the lock as well as some cable, relays and bits that I already have knocking about. If, on the other hand, I need a separate PSU, it potentially gets a bit more...

Thanks @sparkymarka! Any particular reason? Should be more than enough capacity in the PSU200XP (which, to be fair, is already overrated for its use) but sure there's something I've not thought about here.

Not sure if you got this bit sorted, but you don't need SmartCom to use HA (although it will work with one) - in fact, what you really need is a dedicated SmartCom / ComIP that isn't being used for anything else (e.g. Texecom's own app) as the two don't live together especially well due to the...
