Domoticz

I've been messing around a lot with a Domoticz build the last few days, and I've now come to a point where I'm quite happy with how it works. The only problem is that many of the sensors have completely invalid historical data, including wildly incorrect values, and I would like to "wipe the slate" clean and restart the log. Is there an easy way to do this, without deleting (and recreating) all the sensors?

You can open database and delete not necessary data

Allrighty, I'll have a poke around with sqlite3 - after stopping Domoticz, and making a backup copy...
