At some point my house had a second doorbell system installed for the basement. This is a cheap wireless system "carlon rc3105r"

I removed the battery terminals and plugged them into the nodemcu 3.3v and ground and that works ok. I then took the speaker input to the gpio and setup in espeasy as a switch

without issue Home Assistant picked up the mqtt topic as a binary_sensor!

binary_sensor:
  - platform: mqtt
    state_topic: "/doorbell/frontdoor/Switch"
    qos: 0
    payload_on: "0"
    payload_off: "1"

Next up is to cut the original box apart a bit to fit the nodemcu.

Having some issues with the NodeMCU going offline approx once per day which requires manual reboot. Power adapter appears to be ok 5.1v @1amp
it was suggested possibly the doorbell was TOO close to the router causing issues so I have moved it about 15 feet away and I'll see how that goes.

Setting Volume for night time was easier then I expected

    - service: media_player.volume_set
      data_template:
        entity_id: media_player.kitchen
        volume_level: >
          {% if is_state('sun.sun', 'above_horizon') %} 0.50
          {% elif is_state('sun.sun', 'below_horizon') %} 0.30
          {% endif %}

Data template makes things easy!

Solid uptime on the nodeMCU now. Looks like the stock firmware for the Netgear router was the culprit. Dd-wrt for the win!
