Don't received data from C1101 when more sensors on ESP32

[raaq1911]

Hello,

I provisioned Your wm-bus component on WT32-Eth01 (ESP32) with C1101 and ehternet config:

esphome:
  name: wies-rozdzielnia
  friendly_name: wies_rozdzielnia

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging
logger:
  level: VERBOSE

api:
  encryption:
    key: !secret api_password_esphome

ota:
  - platform: esphome
    password: !secret ota_password

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO0_IN
  phy_addr: 1
  power_pin: GPIO16
  manual_ip:
    static_ip: 192.168.70.51
    gateway: 192.168.70.1
    subnet: 255.255.255.0
    dns1: 192.168.70.1
    dns2: 8.8.8.8

time:
  - platform: sntp
    id: time_sntp

    components: [ wmbus ]

wmbus:
  mosi_pin: GPIO12 #
  miso_pin: GPIO35 # INPUT
  clk_pin:  GPIO14 #
  cs_pin:   GPIO15 #
  gdo0_pin: GPIO36 #INPUT
  gdo2_pin: GPIO39 #INPUT

  sync_mode: true 
#  log_all: true
#  all_drivers: true

  clients:
    - name: "wmbusmeters_udp"
      ip_address: "192.168.0.150"
      port: 9022
      format: RTLWMBUS
      transport: TCP

and I received a frame from Energy meter (amiplus) every minium 5 minutes.

After added a more sensor on I2c pins:

• 2x SHT3X,
• 1x MCP23017 (4 switch, 12 binary sensors):

i2c:
  sda: GPIO4
  scl: GPIO2
  scan: true
  id: bus_a

mcp23017:
  - id: 'mcp23017_hub'
    address: 0x20


switch:
  - platform: gpio
    pin:
      mcp23xxx: mcp23017_hub 
      number: 15 #PB7
      mode:
        output: true
      inverted: true
    id: relay_wies_relay_4
    name: "Wies Przekaznik 4"
[...]
binary_sensor:
  - platform: gpio
    id: bezp_rcd_grzalka_up
    pin:
      mcp23xxx: mcp23017_hub 
      number: 11 #PB3
      mode:
        input: true
        pullup: true
      inverted: true
    name: "Wies Rozdz Bezp RCD Grzałka UP"
[...]

I received much less frequently frame from the same meter:

In above image, at 13:05 *.yaml file has only wmbus config.
It's normal? I should use only C1101 on this ESP32 without more sensors on free pins?

[SzczepanLeon]

Yes, it is normal.

Teoretycznie można by to polepszyć.
Przejście na inny uklad radiowy - SX1262 (albo coś podobnego z dużą pamięcią). Odczyt całej ramki wyzwalany przerwaniem. Wtedy ESP byłby odciążony. Niestety są też minusy:

• ograniczenie długości telegramu do 255 bajtów (problem z odczytem watomierzy)
• nie mam czasu na sprawdzenie tego w praktyce
