this is the dubg set as complete msg object that is put at the end of the flow.
i receive:
{"topic":"cmnd/tasmota_mcp/event","payload_end":1,"part1":"topic=tasmota_mcp\npayload=MCPINT_D0=","part2":"topic=tasmota_mcp/eventpayload=MCPINT_D0=","part3":"cmnd/tasmota_mcp/eventpayload=MCPINT_D0=","parts":{"id":"94d4911b.ae57a","type":"string","ch":"payload=","index":0,"count":2},"_msgid":"93636837.391f28"}
and
{"topic":"MCPINT_D0=","payload_end":1,"part1":"topic=tasmota_mcp\npayload=MCPINT_D0=","part2":"topic=tasmota_mcp/eventpayload=MCPINT_D0=","part3":"cmnd/tasmota_mcp/eventpayload=MCPINT_D0=","parts":{"id":"94d4911b.ae57a","type":"string","ch":"payload=","index":1,"count":2},"_msgid":"1083342f.591abc","uno":"MCPINT_D0=","due":1,"payload":"MCPINT_D0=1"}
this is one example of json injected, where, if you would like to implement a function node, i can write in a different way the description field to pass to NodeRed value in a different way that can make easy implement the function
{"Battery":255,"RSSI":12,"description":"topic=tasmota_mcp\npayload=MCPINT_D0=","dtype":"Light/Switch","hwid":"6","id":"000140FE","idx":174,"name":"mcp_luce1","nvalue":1,"stype":"Switch","svalue1":"0","switchType":"On/Off","unit":1}
this is the flow with attached also the debug used and the injection flow on and off.
i think that i make too much complicate the flow tring to manipulate the description filed...maybe i have to change the approach
