Hi,
I have just received a brand new emonth 2 sensor . This is my third one . Previous ones are working normally.
This one does not result in emonhub and no input is created.
Here all actions listed :
batteries are ok,
id is 25 (OFF-ON) as requested (others emonth sensors are 23 and 24)
when battery is inserted green led is on for few seconds and then off
emonhub,conf looks ok as node configuration for id 25 is same as for 23 and 24
emonhub has been restarted
emonbase has been restarted
sensor has been placed near emonbase
Does anyone have any pointers on how to troubleshoot this issue ? Thanks a lot

What is your change? It does require a restart (i.e. remove and replace the batteries) after changing the DIP switch, but if I am reading of the sketch (V2.7 - dated 04/01/17) correctly, the switches will change the NodeID.
Yes, I have one. Great to know that nodeid can be changed on sw.Thanks a lot Simsala.
Could you tell me how to connect the usb-serial programmer to the 6 pins on the emonth board ?
Thanks again
I am wondering how my two emonth sensors worked so far.
The currently installed firmware should uses 23 as initialized value for nodeID. but I have 23 and 24 working.
It will fail, because you will still have two items transmitting using the same Node ID, and that’s not allowed (each will add to the same data stream, making your data wrong). The config file tells emonHub how to interpret the data it gets, by looking at the NodeID that comes with the data, and comparing that with the list of configurations in the config file. It doesn’t allocate the Node ID to the data.
Hi,
I have a similar situation with a brand new emonth 2 sensor - my firs one. I am not receiving anything from the sensor in emonhub.
The emonth has been ordered with nodeid 23.
The batteries are ok - I measured the voltage for both and it’s around 3V.
When I insert the batteries, there is no green led turning on - I tried inserting the batteries without any lights on.
Emonhub config looks ok - it has an entry for nodeid 23.
Emonpi has been updated and restarted.
The sensor is placed at 2 meters from the emonpi.
Does anyone have some ideas on how to troubleshoot the issue?
The LED is turned on by the very first action in the sketch.
Do you have a programmer? If yes, you could connect that and check if there is any output. If there is, then say what you see. You should see (at 115200 Baud) something like
OpenEnergyMonitor.org
emonTH FW: V3.2
and then some more about the radio and the sensor(s) fitted/connected.
But I suspect your emonTH is faulty.
If you see nothing, or you do not have a programmer, email the shop and include a link to this thread.
I have a programmer, but it’s not the one you from the shop so I cannot connect it directly to the board.
Can you tell me what pins should I connect and their positions on the board - I imagine at a minimum Tx/Rx and GND.
I tried to find them on the board schematics, but couldn’t find the labes.
Thank you,
Liviu
