I'm running the current master branch of the enviroplus_exporter on a Pi4
The enviroplus exporter is successfully running as a use that is a member of the following groups
4(adm),5(tty),20(dialout),29(audio),44(video),46(plugdev),100(users),105(input),109(netdev),999(spi),998(i2c),997(gpio)
which should give access to the following devices
crw-rw---- 1 root i2c 89, 1 May 7 12:44 /dev/i2c-1
crw-rw---- 1 root dialout 204, 64 May 7 12:44 /dev/ttyAMA0
crw-rw---- 1 root gpio 245, 0 May 7 12:44 /dev/gpiomem
I've configured systems to mask the serial device to not conflict/confuse the exporter
systemctl mask serial-getty@serial0.service
Prometheus is successfully scraping data from the Raspberry Pi - the service is advertised by consul and Prometheus is picking up the service and importing data.
if I view the host directly on 8000/metrics I see what looks like a full set of metrics

however, if I look at what consul is advertising to prometheus (and therefore prometheus scapes) I see the following, which is basically only the pm device stats.
what is the difference between referencing the fqdn / localhost to node_exporter, I couldn't see anything in the code that would impact this behaviour.
it's easy for me to work around this with consul to just specify the health check as fqdn rather than localhost, but by default the health check is localhost (which does make sense as the exporter is running 'locally'

When I check this, the health check to get the data from consul, is http://localhost:8000/metrics however if I query the fqdn http://fqdn:8000/metrics - I get the full set.
I can verify this on the actual host using curl, eg: curl http://localhost:8000/metrics v curl http://fqdn:8000/metrics
what is the difference between referencing the fqdn / localhost to node_exporter, I couldn't see anything in the code that would impact this behaviour.
it's easy for me to work around this with consul to just specify the health check as fqdn rather than localhost, but by default the health check is localhost (which does make sense as the exporter is running 'locally'
