tcp ip question

[kompio]

Does your project works in tcp connection to otgw, or only serial connections in node red?

[Yveaux]

It should work for any transport, so also for tcp connections.
The nodes just dissect otgw messages, you have to supply them.

[kompio]

I used tcp and I have the error for example : Illegal message length 'T90012500'

[Yveaux]

The check fails when supplied otgw message has a length unequal to 9 (ref https://github.com/Yveaux/node-red-contrib-opentherm/blob/master/otgwdec.js#L21)
The error message suggests length is 9, but could there be a non-printable character in the string or something? (eg newline)

[kompio]

Yes, i think there is the problem .. i work on it.

As temporary workaround you can use the following code:
[{"id":"b11399f4.f38f6","type":"switch","z":"2b03e62a.441eea","name":"","property":"payload","propertyType":"msg","rules":[{"t":"regex","v":"^([TBRA][0-9A-F]{8})$","vt":"str","case":false},{"t":"else"}],"checkall":"true","outputs":2,"x":450,"y":520,"wires":[["eea08ba.95ae878"],["346dbba.695b144"]],"outputLabels":["messages","responses"]},{"id":"dabc1aa3.7b3198","type":"change","z":"2b03e62a.441eea","name":"","rules":[{"t":"change","p":"payload","pt":"msg","from":"^(.*)?\\s$","fromt":"re","to":"$1","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":240,"y":520,"wires":[["b11399f4.f38f6"]]}]

and use messages output
