Finally some progress when I got some help.

In the modified ThingsSpeak sketch the constructor was the problem.
YosemitechY504 y504_1(y504ModbusAddress1, modbusSerial, modbusSensorPower, max485EnablePin, y504NumberReadings); -> did not work
YosemitechY504 y504_2(y504ModbusAddress2, modbusSerial, rs485AdapterPower, modbusSensorPower, max485EnablePin, y504NumberReadings);->Works. I don’t know how I lost one of the power pins but that explains why it worked better from the beginning.

Back to the original problem…
The logger crashes if I set the EnablePin to >0 and don’t set the -D MS_YOSEMITECHPARENT_DEBUG flag
In setup the program enters and don’t return from varArray.setupSensors();

In YosemitechParent.ccp (line 67-69) the debugStream is null if not in debug.

In SensorModbusMaster (line 683-690) it ends up with the null pointer
