Hello Hive Mind. I know I might be trying to get a little ahead of the curve with zigbee on ESPHome but I’m hoping someone can help me get over a small hurdle with my geiger counter interface.
I have interfaced a geiger counter to an EPS32-C6 so I can put radiation counts on a dashboard somewhere, just for fun. I have had the hardware working on a WiFi device, but I really want this on Zigbee.
With a lot of fluffing around I have some code that actually compiles ok, and attaches to the ZHA network. My main problem is that the counts don’t update
I was a software engineer at some stage of my career and have lots of knowledge across many high-level and low level languages. This YAML messes with my head. Anyway, here is the code so far:
esphome:
name: radiation-detector
platformio_options:
board_build.f_cpu: 160000000L
esp32:
board: esp32-c6-devkitc-1
variant: esp32c6
framework:
type: esp-idf
partitions: partitions_zb.csv
external_components:
- source: github://luar123/zigbee_esphome
components: [ zigbee ]
zigbee:
id: zb_node
# wipe_on_boot: once
power_supply: 1
endpoints:
- id: radiation_ep
num: 1
device_type: TEMPERATURE_SENSOR
clusters:
- id: TEMP_MEASUREMENT
attributes:
- id: radiation_attr
attribute_id: 0
type: S16
report: true
device: radiation_sensor
sensor:
- platform: pulse_counter
pin:
number: GPIO20
mode:
input: true
pullup: false
inverted: true
name: "Radiation Level"
id: radiation_sensor
unit_of_measurement: "CPM" # Changed to Counts Per Minute
accuracy_decimals: 0
update_interval: 60s # Count pulses over 60 seconds
# Optional: Filter out noise (pulses shorter than 100us)
internal_filter: 13us
# To pass the raw 60s count to zigbee
on_value:
then:
- lambda: |-
// Publishes total counts over the last 60s
id(radiation_sensor).publish_state(x);
I know I am really getting on at the ground floor on this stuff. The paint is still fresh. If you could point me at a strategy that will get the code going with the clusters, or whatever, that is available now it would be appreciated.
Once this is going I’ll write up the project in a blog so it can be replicated by other HA community members.
OK. I added the setAttr lines to the YAML. Still no joy. I am not convinced that the device has been updated. It is making all the right signs on the compile and install, but the device doesn’t seem to be updating to anything different. I have cleared the compile files for a fresh rebuild, removed the device from the ZHA integration, then reinstalled. Device seems to interview properly, but the number doesn’t increment at all. Shows 0.0 (since it is using a temperature reporting function).
I have also tried erasing the flash memory with the relevant python command, then reprogramming.
I also started adding some LED functionality but have left that our for now for simplicity.
I did add a couple of extra lines to put in a project and version number. When I can see them in the attached device on the Zigbee network I will be happy.
Any clues where I should start digging from here please?
That part will definitely not work and you have to remove it.
At worse, it creates an endless loop (you publish the state on itself each time the state changes).
Generally speaking, no clue on the quality / working status of the component you are using…
Thanks for the possible clue. As it stands it seems to communicate with HA when first connected but then there are no further updates to the data. Will keep digging around that.
The device I am using is an ESP32-C6. I did have this working successfully on the WiFi network, but would like it to be on Zigbee. So the hardware is good I think.
