Active polling of read values crashes the heat pump #10
Description
After the latest update of the ebusd-configuration (PR john30/ebusd-configuration#316) many Home Assistant users experienced heat pumps, which were shutting off (after 5 to 10 minutes) although the energy integral was still negative. Because of that the configuration changes have been reverted.
During debugging (see john30/ebusd#1205) we found out that ebusdpy and the MQTT integration actively poll read messages and that the new configuration contains read values, which should not be read by a second master (because it will prematurely shut off the heat pump). The theory was successfully tested with the MQTT integration, which is why I am opening this issue.
This part of ebusdpy actively polls read messages:
Would it be possible to make active polling optional to prevent such system crashes?
