Thanks @residualimages (and @merck )!!! Exactly what I needed. Was a bit more doc surfing to figure out the API for command tx vs the actions found in the upper portion of the docs but… got it working!!
And for anyone trying to do things with HomeAssistant, the quick and dirty version was using a rest_command…
rest_command:
fireplace_on:
url: http://192.../v2/devices/.../commands/.../tx
method: PUT
headers:
BOND-Token: !secret bond_token
payload: '{}'
fireplace_off:
url: http://192.../v2/devices/.../commands/.../tx
method: PUT
headers:
BOND-Token: !secret bond_token
payload: '{}'
