Hi Howard, I believe you asked me a while ago if I was going to use a second BME280 to measure the inside temp and humidity, I said no I wanted to use the Si7021, but now I want to switch over to use

Helloo Im curently build OCS. I use 4 channel relay to control power for mount, actuator, DSLR and raspberry pi. But for some reason t he on/off status of the devices is showing up in reverse in web s

Hello, I am new in this group and I want first to warmfully thank Howard Dutton for his generosity. I am planning to build a Rolling roof observatory and would like to use this OCS system, at least as

Lots of reading on OTA or using alamode, lots of confusion. So I when back to step one, how to update my sketch to the OCS Arduino mega2560 with what I have around the observatory. 1. I already am usi

I'm 3D printing the fixture for my SQM right now. If this works out I'll post the design and stl files. This is for the Adafruit TSL2591 sensor which sets into the four cut-outs. A weak slightly conve

Hi Howard, I'm running the 2.0g and it works fine ! I wired the heater on a relay following you advice and switch it on only in extreme conditions. The rest of the time i switched it off since the box

We are due for some cold weather this week, so I wanted to see how the setup will work. I still have to add the sensors but wanted to test out the main boards. I also worked on the relay outlets, I di

Since I don't use a warm room, I would still like to monitor the temp & humidity inside the observatory. Reason for this is to set the exhaust fan to kick in at certain temp or humidity range. Could I

Not having any luck trying to get the weather bme280 sensor sketch to work. The OSC tab already has the "void setup()" and "void loop()" claimed. I copied some of the code over to the OSC tab, then I

Hello to all , I'm target to build a experimental board for sqm detector for fun, And i have start this tuto .. (electronic in order) , and i have discover this new group by onstep . Than it's more in

Just checked the updated sketch, it is a lot easier to read and decipher, lots of work on your part, Also thanks for the example code on sensors. Thanks again for the changes Nino

Hi Howard, For feedback I'm testing this version and can't update time. Downgrading to 1.4f and same ip timeserver and time is now ok Koal01

Howard, I intend to use relay 4 to monitor heating in the box when it's freezing. This relay was designed for heating an observatory but i'm not going to use it in the near future. The relay to be use

I just double checked my relays and noticed I ordered 10amp 8 channel relays, will these be okay for my needs? the only big drawn will the the garage door opener for the roof and exhaust fan for humid

I'm testing a way to protect IR sensor from bad weathers (rain, humidity, freeze) to keep the lens as dry as possible. Some times bad conditions can affect and skew its sensitivity. Here are some scre
