Namron Zigbee Thermostat compatibility - econex - 06.07.2025

Hello!
I have bought the Zigbee RS232 GW and a few Namron electric thermostats for a specific project. The thermostats are Namron Zigbee Touch Thermostat 4512752.
I checked the the Zigbee Compatibility list and found that Namron Touch Thermostat 4512737 was compatible, but it seems like that particular thermostat is no longer in production (not as i could find, so i hoped the 4512752 would work).

I get this as device info:

Manufacturer: _TZE204_p3lqqy2r
Model: TS0601

Device type: Router
Power source: Mains
Receive when idle: Yes

Endpoint 1
Profile: 260
Input clusters
- Basic (0)
- Groups (4)
- Scenes (5)
- 61184
Output clusters
- Ota (25)
- Time (10)
When I monitor it reports "empty" messages when i change setpoints (see attached screenshot).

I have a resident script that tries to read from the normal attributes of the device:

Code:
-- Set the polling interval in seconds (e.g., 60)
local poll_interval = 60

-- Initialize lastpoll timestamp if it doesn't exist
if not lastpoll then
  lastpoll = 0
end

-- Check if it's time to poll again
if os.time() >= lastpoll + poll_interval then
  -- It's time, so update the timestamp immediately
  lastpoll = os.time()

  -- Load Zigbee library
  local zb = require('applibs.zigbee')

  -- Device info
  local mac = '3425b4fffecf73b8'
  local endpoint = 1
  local cluster = 0 -- Basic Cluster

  log('--- Polling Thermostat ---')

  -- 1. Read the Measured Temperature (Attribute 65506)
  local temp, err_temp = zb.cmdsync('getrawattribute', mac, endpoint, cluster, 65506)
  if temp then
    -- To write this value to Group Object '1/1/1', uncomment the next line
    -- grp.write('1/1/1', temp)
    log('Thermostat Measured Temperature: ' .. tostring(temp))
  else
    log('Failed to read temperature. Error: ' .. tostring(err_temp))
  end

  -- 2. Read the Heating State (Attribute 65508)
  local state, err_state = zb.cmdsync('getrawattribute', mac, endpoint, cluster, 65508)
  if state then
    -- To write this value to Group Object '1/1/2', uncomment the next line
    -- grp.write('1/1/2', state)
    log('Thermostat Heating State: ' .. tostring(state))
  else
    log('Failed to read heating state. Error: ' .. tostring(err_state))
  end
end

But its timing out (see errors in attached screenshot).

Am I correct in assuming that this device is not supported?

RE: Namron Zigbee Thermostat compatibility - admin - 08.07.2025

Most likely you need to specify manufacturer code when reading these attributes. Try 0x1224 or 0x125D:

Code:
local manufcode = 0x1224 
local temp, err_temp = zb.cmdsync('getrawattribute', mac, endpoint, cluster, 65506, manufcode)

You can adjust the script sleep interval as needed instead of checking the time in the script.

Another option is to monitor report messages coming from ZigBee: https://kb.logicmachine.net/libraries/zigbee/#resident-script-for-monitoring-several-devices
