reef-pi is not really aware of any buses, it uses what linux/sysfs gives (/sys/class/bus/w1/....). So all the magic is done by the great device driver authors in linux :-)

yes. it exposes those reading as analog sensor, you have to model them through ph module for alerting and equipment control based on those valuesDoes reef-pi support power monitoring on the HS300 or other boards that have the hardware?
I’d like to use power draw to trigger alarms and macros if possible (ie primary return pump starts drawing more/less power, turn it off and use the backup). Might be also interesting to combine triggers with a flow meter etc down the track also.

So I purchased this when I bought my Pi and was wondering if there is a way to use it to control dosing motors through the reef-pi. Amazon product ASIN B07Y54FKC6
I found where someone said it is the same thing as a PCA9685 board. but I can't figure out how to configure it within the reef-pi configuration. Any help or input would be appreciated, even if its that I can't use this board for dosing. Was just trying to make use of it.
Thanks
Yes and also use it to control equipment or alert , by treating it as a ph sensor . Hs300 driver exposes 6 outlets and 6 analog sensors, the analog sensors provide current monitoring valuesI can get the Kasa 300 to give power consumption and display it on my ReefPi?
Must learn!
I’m not sure reef-pi will work with it. I have never tested this,So I purchased this when I bought my Pi and was wondering if there is a way to use it to control dosing motors through the reef-pi. Amazon product ASIN B07Y54FKC6

Sad to hear that. By any chance did you test if the power is going till the relay ? I.e the relays are broken and everything including pi till the relay board is working correctly ?![]()
I've been using these relays for about 6 months now and have had a total of 5 die on me. Three in the last 48 hours.
Any suggestions on a better way?
Yes . You can combine the ph circuit with l293d/ doser circuit in a single unitLooking through the guides getting ready to place my parts order and noticed in the reef-pi guides the PH monitor and doser are individual units from everything else. I am building my Reef-pi on a raspberry pi 4. Is it possible to build everything on one unit or do they have to be broken off from everything? If it can be done, would it be possible to get help with the parts list for the PH Monitor and Doser and whats needed/not needed compared to the guides?

so it is confirmed that the songle relay's itself are not working, rest all circuit (pi and relay module [passives]) are fine. I have not much to advice, other than sticking to sainsmart like reputed vendor. Although, they all use songle relays.Thanks Ranjib.
Yes. Did the voltage test with multimeter. Got power on the common pin on the relay, but they aren't switching.
Hi Ranjib,
thanks for reef-pi!
I'm in the process of implementig reef-pi for my - sorry - freshwater fish-tank.
I cannot get to work the pi-camera with reef-pi.
I setup a 'fresh' raspbian on a Rapsberry Pi 4B.
I configured reef-pi to use the camera. I rebooted the raspberry.
The pi-camera is working when I test it in a terminal window with: 'raspistill -o bild.jpg'
I can read temperature. I can switch relais. I can dimm an LED. But the camera isn't working...
What could be wrong with my setup? Do you have an idea?
Thanks, Litserv
