Has anyone created a “Personal Alert” for openHAB?
Like a fob that creates a, “I’ve fallen and can’t get up” message?
A simple way might be a small hardware button like the Hue Smart Button (Hue Bridge or other Zigbee (I think?) Bridge / USB Stick needed) in combination with a rule sending Telegram Messages / Emails to predefined contacts…
Maybe in combination with a color light that is switching to red to show that the button press was picked up and the emergency messages where send
But would that be reliable enough for you? Hue Buttons work mostly reliable for me - but is 99% reliable enough? And after that the openHAB Hue binding has to work, the message service binding, the Phone of the person (s) receiving the message, …
One example - my wife was no longer getting certain messages because I had openHAB sending them via Telegramm - and her iPhone had automatically deleted the app to save storage… Took her months to mention that she wasn’t getting these alarms anymore…
I looked into this a few years back and ultimately decided for something as critical as this a dedicated special purpose service would be far better than anything I would create. I couldn’t possibly maintain the sort of uptime and reliability required for something potentially life critical like this.
Felix,
I like your idea of the Smart button. I must have looked at a dozen or more similar buttons over the last few weeks. I am hoping someone got one working with openHAB. I don’t like the idea of reinventing the wheel.
If you use the Hue Bridge & Button:
- Binding: Philips Hue - Bindings | openHAB
- connect Hue Button with Hue Bridge
- add Things for Bridge & Button to openHAB via auto discovery
- add a messenger service (email, Telegramm, Twitter…) to openHAB
Add a rule similar to this (rule written in Jython):
@rule("Send Emergency Message", description="Alert Neighbours", tags=["message", "emergency", "telegram"])
@when("Channel hue:0820:xxxxx:button1:dimmer_switch_event triggered 1002.0")
def sendServiceMessage(event):
sendServiceMessage.log.info("Rule \"Send Service Message\" triggered")
bot1 = actions.get("telegram", "telegram:telegramBot:bot1Service")
bot1.sendTelegram("Emergency Message")
Will be similar with other buttons / messenger services…
Rich,
I know what you mean. I am trying to cover all aspects of security and reliability.
I will also look at a method using cellphone communication. When I purchased this house the previous owners had a very sophisticated and expensive security system (Vivint). When I considered picking up the they tried to rip me off so I dumped them. I took over all the door sensors, window sensors, heat, smoke, and CO sensors, etc.
I removed the cell circuit board from their control panel. At the time a company, alarm.com, would provide that service but I have yet to interface openHAB to alarm.com. That will be my next question to the community after I resolve the personal alert issue. Assuming alarm.com still provides the service.
Felix,
I really want a fob that a person can carry around their neck or something.
