MHO-C122 not supported in Zigbee2MQTT

[wimb0]

MHO-C122 seems to be missing in the zigbeetlc_v0121.js converter file. If I understand the converter file correctly, it should show up as a LYWSD03MMC in Z2M?

I flashed one with the Zigbee firmware, and Z2m shows it as not supported:

[robvanoostenrijk]

Your MHO-C122 should be natively supported in Zigbee2MQTT: https://github.com/Koenkk/zigbee-herdsman-converters/blob/9e4c840b5466dfd0891039ddf66056fbc5e9bc9e/src/devices/zigbeetlc.ts#L121

[wimb0]

I know, that is why I created the issue here. 4 convertred LYWSD03MMC devices work fine, but my 2 MHO-C122 do not want to work with Z2M. I tried resetting them, and rejoin, but they stay Unsupported.

Zigbee2MQTT version 1.40.0-1 (HA addon)

Relevant logs from Z2M.

[pvvx]

Most likely https://github.com/Koenkk does not support manufacturerName: 'MiaoMiaoCe' https://www.miaomiaoce.com/

[robvanoostenrijk]

@pvvx Looks like you are correct. That is the issue here. Is this a firmware issue or MiaMiaoCe is the correct name?

@wimb0, once @pvvx confirms I'll raise a pull request against the converter in Zigbee2MQTT to rectify the manufacturer name to what the firmware is reporting.

[wimb0]

Your are correct. I see that the MHO-C122 with latest firmware reports the vendor as MiaMiaoCe, not MiaoMiaoCe:

[2024-09-03 08:33:32] warning: z2m: Device '0xa4c138e3a1049a21' with Zigbee model 'MHO-C122-z' and manufacturer name 'MiaMiaoCe' is NOT supported, please follow https://www.zigbee2mqtt.io/advanced/support-new-devices/01_support_new_devices.html

I'll try to fix the custom converter and see if that helps.

The correct name should be MiaoMiaoCe. Print on the back of the device says: MiaoMiaoCe Technology (Beijing) Co., Ltd.

[robvanoostenrijk]

We'll wait for pvvx to confirm if this is a firmware typo or not. If not, I'll change Zigbee2MQTT upstream.

His comment indicates it should be MiaoMiaoCe, as per the official website. In that case the firmware manufacturer is wrongly set (letter 'o' missing).

[juha63]

sensorEpCfg.c:

#define ZCL_BASIC_MFG_NAME     {9,'M','i','a','M','i','a','o','C','e'} // MiaoMiaoCe

This has never changed since the first commit and has always been "MiaMiaoCe". Same with MHO_C401N.

Maybe it's better to stay with this error and change the converter in Zigbee2MQTT? Otherwise we all have to reflash all our devices ...

[wimb0]

Maybe fix both? Correct name in new firmwares. Both manufactureres in Z2M converters.

[pvvx]

Ver 0.1.2.3: Added the ability to change the "manufacturer name". Changing the structure of saving the model and the manufacturer name. Corrected manufacturer name "MiaoMiaoCe" for MHO-C122 and MHO-C401N.

[wimb0]

Thanks for the quick fix! Will the new firmware be available as OTA in Z2M?

[pvvx]

Unfortunately I do not support or use Z2M.

[juha63]

@wimb0: You should be able to do a local OTA update in Z2M using the bin file 1141-020b-01233001-ZMHOC122.zigbee

[wimb0]

I've updated via local OTA. My MHO-C122 with fw v0.1.2.3 is working fine now!

[wimb0]

Since this issue is resolved, I'll close it.
