Re: [Owfs-developers] Temp Logging

[Sorry if the discussion on RRD is off topic with respect to OWFS] I think that when you are collecting up to a few hundreds different metrics, sqlite + any scripting language + AJAX is fine (and probably the best option.) When you go into the range of 1k up to 100k different metrics, collected

Re: [Owfs-developers] Temp Logging

Speed? Wrt what? Db reads/writes? Db queries are vanishingly small time wise, I've found, especially compared to the ajax POST or GET. To answer the OP's question, for graphing I use jqplot. This way my client does all the processing, and they can customize their plots on the fly rather than s

Re: [Owfs-developers] Temp Logging

If your sensors are powered you can dramatically improve the read speed by writing to 'simultaneous/temperature'. Depending on your setup there may be several of these, I read all of my sensors, then write '1' to all of the simultaneous/temperature registers, then do all my control and logging

HI Colin I am open to ANY suggestions. What would you recommend ? I have since got everything working. Also down to 23 seconds per read. This is for my home automation / monitoring project. My raspberry pi running owfs is for all monitoring (eventually some control) Leviton HAI for s
