Had hive in old house, installed nest in new house, of the two massively prefer nest, hive may have changed but it used to be come in at X go off at Y. Nest you set it to be a temp at a time and it knows how long it takes to get to that temperature and comes on in time to get you to that temp, which i vastly prefer
I have the smoke alarms around the house, as well as 3 nest cameras and like how it’s all in one app. The cameras recognise people so tell you the post lady is at the door etc. Smoke alarms and cameras both give push notifications and app access
Also had a nightmare with BG as they damaged my heating system installing it and wouldn’t admit to liability so it cost us £150 for a repair. Had a few brief issues with nest but they’ve been quick to resolve.
Ultimately comes down to cost and which features you will make the most of and if you would expand it to other devices, look at what each company offers
To comment on lighting etc every bulb in our house apart from the en suite and downstairs bog is a hue full colour bulb. We also have garden lights and light strips in garden, behind desks, lights behind tv etc and behind sideboard unit that sort of thing. They don’t have to be on colour but we do use the colours quite a lot
Everything is controlled by voice or motion sensor. We have wall switches still and they work for off on if needed, but we rarely use them. Lights are grouped and we have routines written in Alexa, and via Harmony, to automate things. For example to watch a film on Nvidia shield, it’ll turn on the tv, switch to the right hdmi input on the receiver, set volume level, turn on the Nvidia shield and if it’s dark, set the lights to an appropriate level.
We’ve got routines for all sorts, and at night motion sensors trigger the lights for us. We have ones that boost the heating for x amount of time, or that turn on all sonos devices and my receiver which is linked and starts a playlist etc. There is also geofencing so we turn on the hall and kitchen lights once it gets dark once we are within 500m of the house so that we can bring shopping in easily, and turn off heating or lights when we leave the house, other then home presence mimicking routines
Coloured lights can sync to music when we have friends over, tv lights sync to content in the screen and my pc lights do the same. Pc and home cinema setups are both pretty high end and adds to the experience
I also have a stream deck on my pc so can trigger much of this at the push of a button, or can use apps but it’s 99% Alexa. For which there is an Alexa device in every room. There are cheaper smart lights out there then hue but hue are consistent, good customer service and huge product range to choose from. Compatible with zigbee so lidl smart plugs work with them (we used to control the Christmas tree, and I use one for some non-smart garden lights and also my neon sign in my office)
None of this is needed or essential, but we like having this level of automation.
I take advantage of deals;multi buys, ebay codes, buy used and do topcashback so hasn’t really cost me a huge deal.
