Xiaomi Mijia door- and window Sensor 2

Image
Product code: MCCGQ02HL Dimensions: 34.0 x 32.7 x 14.5mm Operation temperature: -10C ~ 50C 0%-95%RH Connection: Bluetooth 5.1BLE Battery: CR2032  This new Mi sensor is a bit different than the older Mi door and window sensor. In the first appearance you can see that it is a bit bigger. There are a few reasons for that: one is that it uses a more available battery: CR2032 and not the CR1632 in the older version. The other reason is that it also has a light sensor where it can detect bright and dim situations. The old version connects through Zigbee while this one connects through Bluetooth Low Energy. To use this in your home automation setup you will need a Bluetooth enabled hub like the newer Mi home hub 3 (ZNDMWG03LM).  It has on top of the normal open/close notifications a couple of schemes like "alert after x seconds open/closed".

Xiaomi light sensor

Model number: gzcgq01lm Product size: 41 × 41 × 15mm Wireless connection: Zigbee 3.0 Sensitivity range:  0 ~ 83000 lux Battery model: CR2450 Operating temperature: -10 ℃ to -50 ℃  0% -95% RH This light sensor will measure the light intensity from 0 to 83000 lux. The range is adequate to measure full darkness (0 lux), sunset/sunrise (40-400 lux), overcast daytime (1000-2000 lux), and a sunny day (110000 lux). In the sensor are two magnets so you can stick it to any metal surface. Because this sensor uses the zigbee 3.0 protocol it will only work on the newer Mi home hubs like the ZNDMWG03LM.

Alternative implementations for a door sensor - doorbell indicator

Image
Product used : Xiaomi Mijia Smart Door & Window Sensor, but any door sensor will do I wanted to know when some one rings my doorbell to notify me when I cannot hear the doorbell, when I am in the garden for example. In combination with a webcam I can see who is at the door when I am not at home. I know that there are products on the market that can fix this, most of them are not visual appealing, are expensive, and/or requires you to pay a monthly subscription. I think my doorbell looks fine, so I do not want to change this, and to be honest: it is more fun to make something yourself! The model of doorbell I use works with two magnetic coils which actuates a metal rod which then hits the bell. Magnetic coils can also activate reed switches because they are magnetic, so let's try that! I taped a door sensor next to one of the two magnet coils to see if it will work. After some moving the sensor around and ringing the doorbell I found the best spot. I marked it and glued it to...

Adding a Trådfri Wireless control outlet to Philips HUE

Image
Product code : 903.561.66 Specifications: Max power: 3840W Ikea has really cheap remote control outlets which cost about 9.99 euro. They work the same as the Philips HUE ones, just simple on/off. They are a bit bigger than the Philips version and are not that aesthetically pleasing, but they are a lot cheaper.Q to Pairing them with the HUE hub is pretty straightforward if you did this before. Reset the Ikea outlet, move it close to the hub, enable Touchlink, search for the device. After adding non-HUE devices to your HUE hub you can no longer update those devices. This can be a hassle.

Product code : Sothing WN1803 Specifications Battery and power consumption: CR2032 / 3V 10uA Accuracy: ± 5% Light indicator: Red/Green/Blue Weight: 20g Size: 131x25.1x10.9 It seems that there is a sort of new Mi Flora sensor . It is produced by a different company, but also licensed by Xiaomi. It looks pretty much the same as the Mi Flora bluetooth enabled sensor, but that is only at the outside. This version is very much simplified compared to the original and is not really a smart sensor. It does not measure fertility or temperature, the sensor only measures humidity and reports it's result with a RGB led: Red: not enough water Green: enough water Blue: too much water The humidity sensor is a capacitive sensor which means that it will not deteriorate over time like the shiny sensors . There is no app, so it only reports by pressing a (physical) button on the device. The led lights up and gives an indication about the soil humidity. Given that it requires you t...
