Support for Heaters in Openluup

[therealdb]

Hey @akbooer,

heaters support seems to be broken in the device console:

it's a D_Heater1.xml/D_Heater1.json/urn:schemas-upnp-org:device:Heater:1 device, that in Vera is rendered like an heating only thermostat. Thanks!

[akbooer]

Not familiar with this one - what's broken? What does it look like in Vera and/or AltUI?

openLuup doesn't use JavaScript to render panels, since it's done server-side. There's an openLuup module openLuup/panels.lua which can be customised with arbitrary HTML to render any specific device type in any way (icon / panel / status & control page.)

It's a thermostat with heating only. Vera and altui are rendering it correctly. I'll try to take a look later at the panel. Thanks.

I've just remembered that I included a facility to customise the display of device classes without the need to hack any openLuup file!

The openLuup console looks for files (in cmh-ludl/) of the sort U_devicetype.lua to render that type. They have a specific structure, with three functions for icon / panel / tab). Here's a simple one (incomplete in terms of functionality) for the heater (U_Heater.lua)

-- user-defined Heater device panel
-- using openLuup XML module and W3.css framework
-- 2020.08.21  @akbooer

local xml = require "openLuup.xml"
local sid = "urn:upnp-org:serviceId:TemperatureSensor1"
local h = xml.createHTMLDocument ()    -- for factory methods

local function control (devNo)
  return 
    h.div{ 
      h.div {h.h5 "Heater Control and Status Tab", "Anything you like can go here!"} }
end

local function panel (devNo)
  local T = luup.variable_get (sid, "CurrentTemperature", devNo)
  
  local mode = h.form {class = "w3-container w3-form w3-third", onchange="this.form.submit()", 
    action = "html_request", method="post",   -- this is not the correct action!
    h.select {name="Mode", id="Mode",
      h.option {value="Heat", "Heat"},
      h.option {value="Off", "Off", selected=1},
    }
  }	

  return 
    h.div{ class = "w3-row",
      h.div {T, 'º'},
      mode }
end

return {
  control = control,              -- device control tab
  panel = panel,                  -- device panel on the Devices page
  icon = nil,                     -- override this to change the device icon
  }

which then shows the device like this:

The functions in the module can return either plain HTML text, or (for dynamic pages) an openLuup HTML DOM model. I hope there is enough in the example to get you started (if you want to) but feel free to ask, of course.

Thanks for the update. Heaters are indeed part of the the standard Vera device files, so I was just pointing that support for a standard type is missing in the console. My request was to include it in a future release.
