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.Thanks!
FYI - This is the setting that is working (and squeaking).
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 aquariumsI 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.
@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!Very informative. Thank you for sharing.

Haha, but that also means they are easy to take care of. I'm into slowly growing the coral collection as I come across interesting stuff, so the mushrooms take up some otherwise uninteresting space. The kenya tree may need to be trimmed down first though.Careful with those green mushroom, they can be invasive.
Not yet. The API for 3.0 is not finalized and will change in next couple of months. I'll keep you posted.
Looks awesomeOh and here's my latest UI for the reef tank in Home Assistant. The development of the lovelace UI has come leaps and bounds since my initial install so I've been playing with it quite a bit. I should add, almost everything is done through automations based on data coming in from the reef weather, etc. but this is just so I can keep an eye on it and make sure everything is going smoothly.
Sorry for the late reply, I havn't checked in here for a bit.
