How to get help in groups

Another attempt at Answer to "I'm new what camera / automation should I get?"

I'm seeing multiple posts a day with people asking vague questions like:

  • What is the best security camera?
  • What is the best hub?
  • What is the best security or camera system?

Most of the responses are not any better. Lots of I use this and love it or I tried this and hated it.  With a vague question there can be not good reply other than asking for details. You do not see people asking what is the best vehicle or the best entertainments system? Ok maybe the second one from time to time but the reason you do not see people asking the vague question of what is the best vehicle is they have seem to get what you plan to do with it matters. A bike might work for some and odds are most will end up with some sort of car or SUV but there are many factors to take into account like:

  • distance you plan to drive 
  • number of passengers you may need to haul
  • other stuff you may haul or tow
  • any special needs equipment
  • your driving habits as in want good pickup or braking
  • how well the seating accommodates you and or your passengers
  • safety factors like armor or crash handling

Or in the case of the entertainment system a smallish 720p smart TV with a Netflix app maybe all one person wants while another  may want to have a large 4K TV linked to a PC or Roku with a cable like subscription to see the show they may want plus a DVD player or Plex setup for stuff that can not be streamed. Then there is surround sound, voice search and such which some would assume to be include while others deem them frivolious.

In short you need some basic specs before you can talk brands and models.

For example if you are looking to add one or more security cameras, are you looking looking to just get notified or want actionable footage. I have multiple posts on just figuring out the specs you need for a camera. Starting with "What is the best camera for X?"

A home automation hub like an entertainment or security system is even more subjective with virtually infinite options to work with. It should be obvious that any package "system" will be a starting point at best and only makes sense is it is cheaper than getting the parts you want and can use later separately. The blog where this post is located, Adventures in Home Automation, chronicles stuff I've tried to solve the problems I want to solve.  These posts might give you ideas of what you can do to solve yours. Note however this blog only goes back to 2016 after I'd already moved to Homeseer so most of the posts involve it. I started with X10 stuff back in the early 1980s adding TimeCommander Plus in the late 1990s then Insteon devices up till 2014 when keeping it all going outweighed the time savings of having it. Though I did not remove the last of it till 2016. Between 2014 when I bought my first modern home automation hub via the SmartThings Kickstarter, and moving to Homeseer I also tried 4 models of Vera hubs and 2 Lowes Iris hubs. The point being I went through a lot of them before finding that worked for me. One of the reasons I went to Homeseer was than I have 3 buildings to cover. My home, shop and barn which need their own network of devices since Z-Wave and Zigbee do not do well over distances. Note I see people claiming they can use them between buildings and even over 100 feet line of sight but I've never seen anything like that myself. I would be VERY sceptical of such claims. Going with Homeseer let me have one interface for the networks in all the buildings. Plus it is made to handle a large number devices unlike many of the popular hubs that are controlled and configured mainly via a phone app. I generally do not suggest it as a first home automation hub though because it is aimed at the market between the basic DIY hubs like Vera and SmartThings and the pro install system like Crestron and Control4. As such it tends to cost more and be a bit harder to setup than the basic DIY hubs. Though some things are actually easier to do in Homeseer than Vera or SmartThings and some things others do better. For instance Home Assistant has a plug in to talk directly to a Wyze sense hub that has me thinking of linking a Home Assistant instance to my Homeseer. Another thing to keep in mind it each hub has its way of doing things. Somethings that are point and click with one require programming with another.

So when it comes to choosing a home automation hub ask yourself:

  • Am I looking to do automation or just remote control? Automation is where things happen on their own like walking into a room and the lights come on versus you saying a command or pushing a button. You will often see both called automation and gateways like Hue and Harmony called hubs. There are even grey areas like Echo Plus which has a Zigbee interface and limited automation functionality.
  • What do you want to control and monitor? Make a spreadsheet of the hubs you are looking at and the things you want to do and fill in the cells with if it will do it and how. But do your research. "Works with" can mean anything from you plug the device in and the hub sees it to you need to build and configure a gateway system to make it work. There will be compromises not matter what you go with. For example this is my sheet of the things I've tried.
  • What skills do you have or want to have? Odds are you are going to have to learn something. Look at some examples to see what it takes to do the things with each. If programming it involved, how easy is it to learn to do. Is there a good community of supporters that can help you if you need it?
  • The whole cloud versus local debate. Avoiding the cloud is best but sometimes it is the only way or so much easier that you are willing to take the risk, at least for now.
  • Track record of company. We are just starting the shake out of companies. Look at their history and customer base.
  • How easy is it to move to another? Probably more of a device thing than hub since there really is no way to move from one brand hub to another yet. Often not even between models of a brand in some cases (SmartThings V1 to V2 for example). Buying devices supported by multiple hubs is always your best bet as is doing things like using a Hue gateway instead of pairing devices directly to the hub. Then if you need to change or replace a hub you can do so much easier.
Lastly remember most of the people posting in groups have only tried one or two things so they really can not compare much and most of the replies will be love X and hate Y.  You will need to gather, filter and weigh it all into something usable. Also I would discount anyone saying they have never had a problem. Everything has problems. Especially out on the bleeding edge where a lot of automation is. There are things you can do like avoiding the Internet / cloud services to make things more reliable but even totally local will occasionally go down.  Like the guy claiming his WiFi goes 300 feet to his security camera you have to wonder what his frame rate is and how many are getting dropped. Odds are he rarely looks at that camera and just does not notice how much it is missing. Till one day he needs the footage of course but then it will be too late. This analogy an installer told me sums it up perfectly. "I have to explain to my clients that if you have only ever ridden a horse and someone gives you a small compact car, you are gonna think it's awesome purely because you don't know you can get a Range Rover or a Truck for the same money."

Winix AM90 Wi-Fi Air Purifier

Winix AM90 Wi-Fi Air Purifier, 360sq ft Room Capacity, Amazon Alexa and Dash Replenishment Enabled

I love my 2 Winix WAC9500 Ultimate Pet True HEPA Air Cleaner with PlasmaWave Technology filters. Been great for going on 5 years now. Been dry enough lately that the vent that pulls in cooler outside air at night into the computer room is pulling a fair bit of dust too.  So I decided to get a third. The WAC9500 is discontinued and none of the current models use the same filters. The Winix HR900 Ultimate Pet True HEPA PlasmaWave Technology Air Purifier, 300 Sq. Ft, White is the follow up to the 9500 but as far as I can see it does not clean the air much better than the AM90. It is even rated for a larger space.  So I bought an AM90 which is $100 cheaper and is supposed to work with Alexa. It also uses the filter, Winix 115115 Replacement Filter A for C535, 5300-2, P300, 5300, 5500 which I ordered once by accident for my 9500s. The filters the 9500s use, Winix 114190 Replacement Filter B for 9500, U300 Air Purifiers are also more expensive and use a plastic cassette that each replacement comes in and so makes for more plastic waste.

Setup:

The setup via the android app was so bad I almost sent it back. Note the C545 model needs it own skill and app.

To get it to finally finish I had to:

  • Get the timing right to see the direct WiFi connection. (You have to connect before unit quickly times out)
  • Have the phone forget the 5Ghz WiFi
  • Let it use the default city as the location.


Took me about 5 tries to get all the way through, having to start over from scratch even after I could see it was connected to my network.

Even trying to change the city later caused the app to completely hang during search. So I ended up leaving it on the default as useless as that is.


Note the Alexa name entered into the app (as in Bedroom) is what shows in lists in the app though in the web interface it shows as Bedroom Winix Air Purifier. You will probably want a longer name, though you can change in the Alexa app later.

Alexa integration:

For Alexa to see the instructions say you have to enable 2 skills

Since I use a password manager I find linking accounts easier in the web interface. Be sure to select Approve before clicking submit.

The Winix Custom Skill is the old "Ask Winix" style.

The Winix Smart Home Skill is supposed to let you say "Alexa, turn on WINIX", "Alexa, increase WINIX" and "Alexa, decrease WINIX" Though this did not work for me. So I looked to create a routine to alias it. After not seeing it on the list at first ( showed as a a fan named bedroom) I decided to rename it.

I tried triggers of "more air" and "increase air" to turn up the cleaner bey neither worked. The less intuitive "full power" did. I then made a matching "half power" routine to set it back to normal.

Reviews complain about WiFi connectivity so I'll have to update after I've had it online for awhile.
