Noob : Cant get Sensor talking to gateway

[mfalkvidd]

@manutremo the gateway is just a dumb forwarder. When the ID request is received from the sensor node, the gateway forwards that message to it's configured interface (mqtt, ethernet, serial, ...). If the controller responds, the gateway will forward the response.

To do your suggested no 1, the gateway would have to keep track of all ID requests and set some time to know when the response from the controller is deemed too slow. That could probably be done, but would require quite a lot of work to get right and to keep compact enough to still fit the gateway in popular constrained devices like the atmega328.

The message in no 2 doesn't exist, as we have agreed on, so this is unfortunately not viable either.

Your suggestion no 3 sounds promising I think. Whenever the node prints !TSM:ID:FAIL, the log parser should spell out that the most likely cause is that no controller is present. I'm not sure how to update the log parser, but maybe @hek can chip in here? At the moment, the log parser seems unable to parse that message at all.

https://www.mysensors.org/apidocs/group__MyTransportgrp.html#details should be updated to mention the controller on the line where TSM ID FAIL is mentioned.

It would also be nice if the !TSM:ID:FAIL message was more verbose (for people who don't immediately use the log parser), but the log messages need to be kept very short to keep the binary size small.

A suggestion for updating the documentation is available at https://github.com/mysensors/MySensors/pull/984
Feedback is welcome.

I have been facing the same problem all day today. Actually as far as I remember my old nodes used to setup the node assignation to AUTO by default.

Was that changed during the last month ? because I was busy at that period.

[mfalkvidd]

@ahmedadelhosni auto id has been default since inception, as far as I know. It was default 2.5 years ago when I first learned about MySensors. So nothing has changed.

[gohan]

It defaults to Auto if no manual define is set, but it still needs a controller or just myscontroller application that keeps track of the IDs and assign new unused ones.

[ahmedadelhosni]

@mfalkvidd That's what I know but as I have said, I have been facing the same error to assign an ID for my node and it was solved when I change it to static ID... strange !

[angeloS]

i was thinking about this, perhaps as part of a welcome tutorial we connect the GW to a gateway (pick one , an easy one). And whilst doing this we simply explain why the Controller is needed.. this would help newbies like me from the start..

Which controller.. well Ive been looking at openhab but settled on Homeassistant, appears more active that OH

@angeloS do you mean to add information to this page? https://www.mysensors.org/build/select_gateway

The getting started guide already mentions (twice actually) that the controller is responsible for handling automatic node id assignment.

If people don't read the getting started guide, will they really read the Select gateway page?

I have the same situation - mysensors relay node can not find parent. I cleared eeprom and entered manually MY_NODE_ID, but it seems that gateway and node communicate, but fail to make final arrengement.

any ideas what I have to check?

There is a problem with messages sent by gateway or received by node: you either have bad power supply for radio on gateway or bad antenna or antenna alignment or too much distance; could also be interference near the node
