Fiddling around with some motion sensors I found that the different brands/types provides cplete different capabilities/options/etc.
Although some info is available in (online) manuals, shops or maybe compare sites (fe Sensoren - Producten vergelijken - Tweakers ), I often mis a lot of crucial details for a good selection.
(fe configurable blind time, function of the light sensor, etc)
Does anyone have a good source for info of should we create it our self?
(related to the use on Homey)
Having four complete different PIRs I will start to see if the community can extend this with useful info about different devices/types/brands.
I use a SonOff-RF bridge to communicate with them.
It’s been flashed with Tasmota. It’s also had an extra firmware added called Portisch. This gives a lot more control and allows it to capture or send raw data if you ever need to. The RF bridge just acts as a listening / transmit device only. It just listens to RF traffic and converts it into MQTT messages. Likewise when also when transmitting.
From there I use MQTT client in Homey (via flows) to either listen to or transmit certain RF commands…
For devices such as motion sensors, buttons , contract sensors and fire alarms etc etc that just transmit data I create a flow to listen for the unique ID code for that particular device
See example .
For transmitting commands to RF devices I use a flow to send raw code to the RF bridge via MQTT…
Can also create Virtual Devices through these methods.
I’ve found most times you don’t need an app for RF gear if you have the ability to learn , or have the ability to send out raw code . I’ve found cheap Chinese gear is very easy to work with as they mostly only use the one RF chipset and protocol. The more exotic and expensive brands can be harder to deal with but using RAW code seems to get around them.
This method can’t deal with rolling codes though. If Homey had its own in built learning APP then some rolling codes could be possible. Not all , but could work with some cheaper products.
If a manufacturer truly wants their gear to be truly secure no aftermarket product will be able to learn their rolling codes and only their physically encrypted hardware will work with their stuff. For things such as garage roller doors sometimes you have to physically tap into the buttons on the controller inside the garage you want to gain control …
I have 2 of these and one Neo Coolcam and the Multisensor 6 is by far the best. I have mine mains powered via a USB charger as they provide much faster response and no need to worry about batteries, but they can run off CR123A if required. Battery life is about the same as the Neo Coolcam.
They can also be ceiling mounted using the optional recessor. I have one mounted this way and it is hardly noticeable in the hallway.
I agree, great sensors, plenty additional information next to the motion capability. But usb power is a must in my opinion, it just burns batteries. In the end I replaced one which used 2x CR123a each half year by a Xiaomi Aqara which runs 1,5 years on a CR2340 so if motion detection is all you need I’d go for a Xiaomi.
I thought the meaning of this topic was to compare motion sensors. Saying they are cheap and battery lasts long is not enough for the charts. How about blind time and configurable sensitivity and stuff like that needed?
