Inputs but no updates – emonTH standard? Setup

Problem:

Inputs but no updates – emonTH standard? Setup

Setup:

I have a new RFM12Pi v2 and an emonTH purchased from the shop. See pictures attached.

Using the Raspberry Pi Ready to go image from: https://github.com/emoncms/docs/blob/master/raspberrypiimage.md

Wireless distance between at one metres

Running on 433MHz

Using Tesco Extra Long Life Akaline AA 1.5v  batterys – swapped for new numerous times

sending data to emonscms.org

LED solid at emonTH power on then blips 18 (I think – difficult to count) times but then nothing. I though there was a 60sec heartbeat?

Inputs come through at power on of emoTH

I`ve followed: http://openenergymonitor.org/emon/modules/emonTH

No values aprt from node19:1 (temperature) at beginning.

No regular updates from any inputs

I ran minicom and rebooted (battery out then in) emonTH

[email protected] ~ $ sudo service rfm12piphp stop
Log is turned off
Stopping RPI: stopped
[email protected] ~ $ minicom -b9600 -D/dev/ttyAMA0

See output below.

Solution?

Is the EmonTH faulty or have I set it up wrong?

Thanks

Aidan Venn

Re: Inputs but no updates – emonTH standard? Setup

Hi avenn,

Good work getting up and running.

It sounds like the emonTH is not detecting the sensors, the LED should not flash. It should come on for a few seconds at power up to indicate successful power up (there is no heartbeat). If the LED flashes it means the sensors have not been detected. Looking at the photo you have incorrectly solderd the DS18B20 into the DHT22 socket. See photo showing how the DS18B20 should be soldered: 

It sounds like the Raspberry Pi is working fine, I can see it's successfully receiving the initial RF test packets from the emonTH (10 -0 count down)

I would recommend you download and install the latest pre-built SD card image for the Pi based on latest raspbian set to work in read-only file system with separate data partition to increase SD card lifespan. This comes with emonHub pre installed.
