Does Nest Secure work with my current domestic safety device

A fantastic, but apparently closed, surroundings
There’s no denying that the Nest Secure, a gadget such as a Nest Guard base station and one or extra sensors and cameras, is an awesome own family of merchandise. The portions look notable, are smooth to install, and you will find every sensor, camera, or extra you can ever need to be built by using Nest. Everything works well, too. Your Nest Hello doorbell can act as a safety camera in conjunction with the Nest Cam itself; you can tell the Nest Guard to ignore that open door by means of swiping your Nest Tag throughout it; you may understand precisely what’s taking place even if you’re no longer home via the Nest app. However, a part of the cause the Nest environment works so properly is that it is using a specific set of protocols for communication.

Zigbee and Z-Wave are enterprise standards in terms of internet-of-things conversation. They paintings properly and excellent of all is designed for gadgets to talk regardless of who makes them. Nest Secure doesn’t use both of those conversation protocols and alternatively, the pieces speak to every other using Thread and Weave. The thread is a collaboration from Google, Samsung, ARM, and others that natively handles IPv6 via an open wi-fi protocol. Without getting too deep, Thread is primarily based at the 6LoWPAN adaption layer. Thread and Zigbee are operating on what is referred to as the ZigBee Cluster Library so ZigBee gadgets can run using Thread for communications, however now not the other way round.

A weave is Nest’s proprietary utility communications protocol that lets in devices to talk securely through their very own peer-to-peer community. Nest has opened Weave support to other groups, but this does not mean that your Nest Cam can work with another company’s gadget. It way the opposite organization’s camera can paintings with Nest merchandise.

Adding a piece vs. Upgrading all of it
If you are looking for a brand new safety device or are taking into account changing a present device with something new, the Nest Secure machine is a fantastic desire. You’ll love how the pieces look and how smooth it’s far to get all of it operating. You’ll probably love the whole thing besides the fee, but this isn’t always something you will be changing very regularly so charge should not be the biggest part of a shopping for choice. You may not move wrong by shopping for a Nest Secure starter device.

However, in case you’re simply trying to upload a digital camera or sensor to an existing device or extending it, Nest is not what you are searching out. There are plenty of other companies that use the extra famous Zigbee and Z-Wave communique protocols, but I’d advise products from SimpliSafe as your nice wager for interoperability. The corporation also makes a tremendous complete system in case you’re looking at the beginning from scratch, too.

Consumer Units, Circuit Protection Devices, and Accessories – A Glossary

Consumer Unit

A patron unit is an electrical device used to distribute power all through a home living. Acting as a safety device, shielding against injury thru electrical surprise, a client unit homes safety devices which additionally protect household home equipment from overload.

A client unit’s first characteristic is the corporation of electrical ‘circuits’, such that the extraordinary ways wherein we use electricity at some stage in the home may be accurately and extra effortlessly controlled. A traditional domestic set up, for example, could have the following circuits: Ring most important for power sockets and items like washing machines and TVs, Lighting, smoke alarms, cooker, shower and so forth.

Main Switch

This is the ‘Double Module’ tool which sits in the long way right-hand side of a purchaser. It commonly has a big crimson bar transfer and acts to isolate the entire board. This manner that with the aid of guide operation it could cut strength to every circuit inside the installation. Main Switches are almost continually rated at 100 amp, allowing it to isolate a set up which draws no extra than one hundred amps in general across all circuits.


Mini Circuit Breaker. An MCB protects its circuit against overload. When as an example a bulb blows on a lighting fixtures circuit the MCB cuts the strength to that circuit, as a result protecting the other lighting fixtures. No other circuits on the patron unit had been affected. An MCB does no longer protect humans against electric surprise.


Residual Current Devices shield a couple of circuits towards earth leakage. This is an essential feature of a patron unit as it’s miles earth leakage which causes electric shock. RCDs degree the quantity of energy flowing into the patron unit against the quantity flowing out. When it detects an imbalance between the two it cuts the energy delivered to the bank of circuits it is protective.

It has to be noted that because of this a fault on one circuit will result in a reducing of the energy to any other circuit blanketed by means of that RCD. For example, an RCD may additionally protect the hoop principal and indoor and outside lights circuits. In this example, a fault at the outdoor lights circuit will knock out the indoor lighting fixtures and all electricity sockets.

It is for this reason that the seventeenth Edition Regulations call for ‘Division of Circuits’ to keep away from ‘Nuisance Tripping’


Residual Current Breaker with Overload (RCBO). This clever tool combines the capability of an MCB and RCD and consequently permits for independent safety on person circuits in opposition to each overload and earth leakage.

Din Rail

The mounting rail upon which can be fitted the Main Switch, RCDs, MCBs, and RCBOs.


The device which connects electrically the Main Switch, RCDs, MCBs, and RCBOs.

Neutral Bar

The terminal bar which accepts all of the neutral wires from the RCBOs and MCBs.
