MQTT controlling OTA mode. Can I get a state from the device?

ESPHome
1

I have a solar-powered node and I put the ESP into deep sleep between readings. I use an MQTT message to enable or disable sleep so that I can use OTA.

Is there any way that I can get the device to post the state of ota_mode so that I can reflect the current mode on my Lovelace page? In other words, “I’m alive- go ahead with the OTA”.

mqtt:
  broker: '192.168.1.124'
  discovery: false
  discovery_retain: false
  birth_message:
  will_message:
  on_message:
    #ota on = turn off deep sleep to permit OTA
    - topic: solar/ota_mode
      payload: 'ON'
      then:
        - deep_sleep.prevent: deep_sleep_handler
    #ota off = turn on deep sleep
    - topic: solar/ota_mode
      payload: 'OFF'
      then:
        - deep_sleep.enter: deep_sleep_handler
