Option to change Evohome update frequency

[smartypantsuk]

I am using the Evohome with a HGI80 and the update frequency of the temperature devices is constant and bombards the system because of 0.1+ degree changes in temperature.

This means that any scripts which trigger on device changes are constantly firing, like multiple times a minute. Multiply that by 7 temperature devices and the scripts are continually firing. God knows what happens to the machine's resources in a larger device system. I've got checks in the scripts to not run the function if various conditions aren't met, but all this does is stop the script running it's entirety and doesn't stop the script being fired.

What is needed is for Domoticz to ignore tiny temperature changes. Most thermostats and temperature sensors use 0.5 degree changes before anything is updated, Domoticz seems to process something along the line of 0.1 degree, I'm not sure exactly but it's small and my logs are like this because of it. So either an option to customize the frequency of updates or have domoticz ignore updates of less than 0.5 or there abouts.

Looking at my logs, I'm actually not sure why all the logging.
The temperature changes don't seem to coincide with the log updates, so I'm not sure why the logs are so constant.
The temperature devices are pushing updates of 0.1 degree changes though, so that is way too small and completely pointless.

I can't help with your issue of the scripts triggering too often, but the entries you're seeing in the logs represent each update that the HGI80 has received from one of your Evohome devices (Main control panel, TRV's, relays etc). Domoticz can't control how often that happens, it's down to the Evohome devices but you can disable the info-level logging for the HGI80 on the hardware page.

You already posted this on the Forum, why a double post ?

This data is received from your devices by USB/TCP

If you want this to be solved, you might need to change the c++ code to store the last value, compare it,
if it is different (or last reception was longer then xx minutes), update the sensor

You need to do this in the CEvohomeRadio class
