+===== Tasmota-Berry ModBus Script =====
+The above script lacks the possibility of changing values on the modbus device (just reading is possible).
+Dies sind Ideen für ein schöneres Berry Script. Dafür muß in der Pin configuration für pin20/21 statt ''None'', ''ModBr Rx/Tx'' ausgewählt werden, um das ''ModBusSend'' Kommando auf der Console zu ermöglichen.
+<code txt console commands>
+ModbusBaudrate 2400
+ModBusSend {"deviceaddress": 1, "functioncode": 4, "startaddress": 4501, "type": "uint16", "count": 1}
+</code>
+Zunächst antwortet dieses Kommando nicht mit ''ModBusReceive'' .
+Andere User schreiben, dass dieser Berry Mode leider Crash gefährdet ist.
