Jeicang JCHT35K9 - Works somewhat!

[pedrams1]

Hi folks!

Been testing my Zen Space Desk (which is actually a re-badged Jeicang JCHT35K9) with the controller.

It mostly works! Connects to the desk as intended and the preset button controls work near flawlessly!

There is just one issue, the height of the desk isn't properly reported. The desk basically thinks it's always at 25.9cm or 26cm no matter what. If you send it a position to move to, it will just move to the top until it hits the physical limit, still reporting 25.9/26cm.

[19:47:21][D][button:013]: 'Desk Preset 2' Pressed.
[19:48:18][D][button:013]: 'Desk Preset 4' Pressed.
[19:48:21][D][sensor:126]: 'Desk Height': Sending state 25.90000 cm with 1 decimals of accuracy

[19:48:43][D][number:113]: New number value: 75.000000
[19:48:43][D][number:012]: 'Target Desk Height': Sending state 75.000000
[19:48:45][D][sensor:126]: 'Desk Height': Sending state 26.00000 cm with 1 decimals of accuracy
[19:48:55][D][button:013]: 'Desk Preset 2' Pressed.
[19:49:06][I][ota:109]: Boot seems successful, resetting boot loop counter.

According to this post it's believed this is the same OEM partner used by Jarvis.

Interestingly, I've tried both the Fully Jarvis and Uplift 2 with identical results - which makes me think maybe the height information is not being decoded properly?

I'm wondering if anyone can point me into the right direction on where to get started debugging this? I'd love to figure this out as a pet project - and hopefully work to get this desk officially supported as it's quite popular in Australia.

P.S. Thank you TJ on building this product, even without the height being able to move to preset positions through Home Assistant has been amazing!

Same here. Jarvis decoder not showing any height at all but Uplift is at least showing your values.

Same here. controller box is the same.
Got 25.9/26 cm whatever the height

It's fixed with the newest Version and Omnidesk Decoder
