    Thanks!
    FYI - This is the setting that is working (and squeaking).

    This could have been related to the stuck PCA9685 frequency bug. My frequency was stuck at 1500hz, @Ranjib had his stuck in the 200's somewhere, there is a new release that fixes the frequency setting.
    Load the new release and try some different frequencies on the configuration---settings---pca9685 freq setting box. Yours may have been stuck and your dosing motors may do better on a different freq.

    Also when ramping up and down your motors may not like the low duty cycles. So try putting something higher than Zero in the min setting box. If freq changes dont help. The motor may not make enough power on a low setting and may be 'lugging' making the squeak noise

    I just upgraded to 2.3 yesterday, so I'll see if a change in frequency helps. In the meantime, an update on some other changes.

    • I've switched the feeder to a continuous rotation auger type on Thingiverse here. The barrel type was pulling in too much moisture and getting gunked up. The python script for running it off of a pi is "fishfeeder360.py" in my scripts repository

    • There is a pump on a Tuya switch that cycles water from a small sump, Home Assistant runs this every three minutes until Reef-pi sees the float switch go Low (usually about a minute), then it has time to fill again.

    • The Amazon Tank is now combined with a aquaponic system as seen here on Thingiverse. The lightswitch and plant_waterer scripts in my scripts repository are triggered by a Home Assistant automation. This also allows for gradual water changes.

    • I spoke to Richard Ross from the Steinhart Aquarium when he spoke at last months Brooklyn Aquarium Society Meeting (a great resource for anyone in the NYC area) and he agreed that the data pulled from NOAA and weather services as surface water temps seemed high for a home aquarium but were probably accurate for Bali. He said he had come across a similar issue at their coral spawning facility and adjusted the data down by 2 degrees - which is the same as I had done through a Home Assistant template anyway. The talk was on coral spawning, which is triggered by moon phases, so coordinating nightlights with lunar data might be next in the works.

    Very informative. Thank you for sharing. Steinhert aquarium is so close by , I would love to interact with Richard and get his thoughts on reef-pi , anything we can do to support research etc. reef-pi is already being used by three universities for different types of experiments, it would be nice to see it supporting my local public aquariums

    @Ranjib when I lived in the bay area I went to the SF Aquarium society meetings - also a good resource. They arranged a "backstage" tour of the aquarium, among the giant pipes and pumps, it was amazing. They seemed very supportive of hobbyists. Richard said they were using Apex for the coral spawning project, but I think they had to modify some things to get data synced up. Seems like a good place to have a more flexible setup like reef-pi, maybe you should get in touch!
