I’m hoping to build a device handler that reports the current capacity of a container (an oil tank, in gallons). I was looking through the existing device types and capabilities and nothing seems like a good fit. Would anyone have any thoughts as to how best to do this?
Thanks for the pointers, but I think I may have not properly described what I’m looking to do. I purchased one these gauges that reports current data back to a customer portal. I am looking to have pull the data off the portal to make it available for alerting (low oil level) and export out through an InfluxDB logger smartapp for long-term trending.
The sensing bit is already done, I just need to grab the values and make use of them. Is a device handler the right way to do this, or should I be looking at a smartapp?
Hi, I am not sure if this Succeeded to write a device handler parsing my arduino humidity and temperature webpage will help you but this is how I made a devicehandler that grabs data from a website I host on my NAS. The idea is that this device handler, instead of querying directly my Arduino board who performs the measurement, goes to a webpage where it access a MySQL database where my Arduino pushes the measurement.
Maybe you can find similarities with your use-case.
