Is Zigbee safe enough to be use in Security environment? PIR, Door Sensor & Door Lock etc. Long time never catch up with Smart home technology so can consider myself a newbie now. Seems Zigbee can be easily hack if manufacturer does not comply to their standard completely.

QUOTE(ozak @ Dec 20 2017, 10:33 AM) Equipment lifetime is not depend on the solar energy. Solar energy is only provide the supply. The rest is depend on the equipment quality. "Solar Panel Warranty 10years guarantee 90% power consume, 25years guarantee 80% power consumeBut 1 thing for sure is the equipment have less device to convert the voltage and doesn't require stabilize. That reduce the equipment cost and longer lifetime. But the setup cost is expensive. Take for example setting up a remote control above. Equipment need and consumption 1) router/modem - 2A 2) Network cctv - 0.5A 3) Sonoff 4channel - 0.5A 4) Led Light 12w - 1A All run on 12V, 24hr accept the Led light which is 12hr. Total consumption around 1.1kw for a day. Calculate the solar supply require is 1) battery of 232Ahr - RM2.4k 2) 300watt panel or 3x 100watt panel. - RM2.1k 3) 25A charger controller. - RM500 4) misc - RM500. Just the solar system is already cost RM5.5k.   " "Solar Panel, Size: 63x57x3cm, Power: 60W 30A Battery size 125*41.66mm Watt tolerance ±3% Peak Value Voltage 18.17V Peak Value current 3.30A Short Current 3.70A Max system voltage 1000V Diodes 0by-pass" Any idea how much the above would cost? Noob in solar. |

QUOTE(ozak @ Dec 20 2017, 10:54 AM) Don't understand your spec. I also don't know what it means. What details do I need to ask from the manufacturer? BTW, they say can run 7/24 1 Ip camera together with 1 wireless AP.What is your solar wattage ? What is the battery Ahr ? 60W refer to ? 30A refer to ? Cause if 30A is 12v x 30A = 360W. And 60W / 12v = 5A. |

QUOTE(idoblu @ Jul 7 2018, 04:08 PM) $100 cheaper? Why not, if you are already planning on getting one. Yes, always wanted to dabble with smart home system.How about Echo Spot? Any special deal on that? Echo Spot buy 2 less 40, so 20usd off each. This post has been edited by adamw: Jul 7 2018, 04:18 PM |

QUOTE(shackks @ Jul 23 2018, 11:39 AM) Yeah, this one is about the same as what I saw in Lazada. You can install Alexa on your phone & integrate all the supported devices with voice command. In fact I just use my broadlink to learn my auto gate but currently have problem. Alexa will not recognised learned remotes so most probably have to treat my auto gate as "Lamp" as recommended in YT videos.https://www.lazada.com.my/products/itead-so...TeXDsL&search=1 Additionally to the above, I'm also worried that if I were to expand the use of smart switches in the future, I might be stuck with the specific brand as these are currently still very proprietary. I don't really fancy switching between apps to control my appliances or lightings. |
