Enhancement: Add history to sensor data

[honkmaster]

Using fakegato-history, you can simply add a history functionality to your sensors. The history, then will be available in the Elgato Eve App. I first seen this feature in homebridge-dht, and really like it. homebridge-airrohr could replicate an Elgato Eve Room device, e.g.:

this.loggingService.addEntry({time: moment().unix(), temp:this.temperature, humidity:this.humidity, ppm:this.ppm});

See: https://github.com/simont77/fakegato-history

That would be nice. +1 :)

@toto Any chance to see ongoing development integrating fakegato-history? Would be awesome. Wouldn't want to miss homebridge-airrohr and fakegato would be the cherry on top. :) Thanks in advance for the time you are investing and sharing you work with us.

@DJay-X I published 1.1.6 which contains #14 and #17 so history should be supported

@toto First, thanks for your work. I already updated to v1.1.6 restart homebridge but didn't see any history starting to record. Am I doing anything wrong or missed something than just updating your plugin? Thanks.

@DJay-X just wait about one day. Fakegato obviously don't show any graph if no historical data are available.

[DJay-X]

Thanks @brandungskieker But shouldn't there be at least a drop down arrow and an empty graph field saying "no data" at the moment? Anyways.. I will check tomorrow again. Thanks again for your reply.

It's working here. History is filling. Thx. 👍🏻

Perfect!

@toto Thank you for the hard work and support.

I installed homebridge and fakegato-history like this: sudo npm install -g homebridge-airrohr sudo npm install -g fakegato-history

I run homebridge with the following command: DEBUG=* homebridge -D

Connection with HomeKit is there and also temperature, humidity, PM2.5 and PM10 shows up correctly in Eve on my iPhone. For temperature and humidity the history is also there.

However history for PM2.5 and PM10 is missing: no data available I think it has something to do with the fact that it isn't stored in the file *._persist.json. See below:

Can you confirm this and tell me how I can solve this?

Thanks in advance.
