Then vzlogger with MeterOCR detecting water consumption changes on a 0.1l granularity.\r\nBoth meter types can be enabled with cmake parameters and will be automatically turned off in libleptonica or tesseract are not installed. So it shouldn't harm anybody. \r\nIf this sounds useful/interesting for others as well I'll add some descriptions on how to setup on the wiki pages. \r\nFeedback appreciated."},"comment":{"url":"https://api.github.com/repos/volkszaehler/vzlogger/issues/comments/72539317","html_url":"https://github.com/volkszaehler/vzlogger/pull/118#issuecomment-72539317","issue_url":"https://api.github.com/repos/volkszaehler/vzlogger/issues/118","id":72539317,"user":{"login":"justinotherguy","id":199173,"avatar_url":"https://avatars.githubusercontent.com/u/199173?v=3","gravatar_id":"","url":"https://api.github.com/users/justinotherguy","html_url":"https://github.com/justinotherguy","followers_url":"https://api.github.com/users/justinotherguy/followers","following_url":"https://api.github.com/users/justinotherguy/following{/other_user}","gists_url":"https://api.github.com/users/justinotherguy/gists{/gist_id}","starred_url":"https://api.github.com/users/justinotherguy/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/justinotherguy/subscriptions","organizations_url":"https://api.github.com/users/justinotherguy/orgs","repos_url":"https://api.github.com/users/justinotherguy/repos","events_url":"https://api.github.com/users/justinotherguy/events{/privacy}","received_events_url":"https://api.github.com/users/justinotherguy/received_events","type":"User","site_admin":false},"created_at":"2015-02-02T21:15:24Z","updated_at":"2015-02-02T21:15:24Z","body":"Excellent stuff!
