I am using 3 valve drivers from MAX! connected to my system through SPI/ti-cc1101. It’s working well, when I send commands they are immediately received byt the devices, but the reading of ACTUAL_TEMPERATURE is weird.
What is happening is that the value I read from the valves remain fixed for a long time (e.g. a couple of hours at night) and then suddendly changes a lot (like 2 deegrees C). The updated values is returned sometimes after sending a command, and sometimes all by itself.
I would like to know whether this is normal because the devices go into some kind of “energy saving” mode, or perhaps it’s homegear which is caching this data (I am using openhab with rrd4j persistence on top of homegear).
