Hi, I found a solution in this post by @Colin to decode 16 bit SIGNED integer, but I have in Modbus register voltage values as 16 bit UNSIGNED integer. If this msg.payload[22] = (msg.payload[22] << 16) >> 16 works to 16bit SIGNED, how to convert 16bit UNSIGNED? Thanks

Do these payload values look right? [image] [image] Demo flow... [{"id":"3cdc61d2.9d548e","type":"inject","z":"f77cda4d.5d7628","name":"go","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":1…
