$30-250 USD

Paid on delivery
We want a script to be able to control relays on a raspberry PI via a cell phone app. The relays will operate different things, we would like the relays on the PI to be able to have time of day and day/week/year scheduling. Also be able to be controlled by temperature sensor/sensores This Raspberry Pi will be powered by a solar system, each relay will need to not power on if the voltage is below a set voltage. We also need email or text alerts, we have a Nagios server and maybe this project can be tied into this system to offer the monitoring we need and a view all PIs on one place.

Hello, I Can provide you the Script /Codes that Control the relays connected with Raspberry pi through Cell Phone/ Mobile App. I have some questions that i picked from your Job Post. - Q1 : Do You want to ON - OFF the relay as per Time and Also relay ON-OFF as per Temperature ? (Please clarify me if i got anything wrong) - Q2 : Which Temperature Sensor you have ? I have worked on relay power cut off with many projects, because i understand this is necessary. I have used solar system as power source of raspberry pi . - Q3 : Please send me the details of solar system that you have ? I will provide you the Codes and Connection diagrams with all necessary details. You can send me message any time as i will be available. Thanks, Chanchal k

Hello. I am expert in Raspberry, Python, C, ... I am expert in Web server with PHP, Apache, HTML. I think you should make a web server run on each Raspberry PI. You can access web page and monitor/control PI. Could we discuss more for details/price/time? Thanks.

We have vast experience in designing such systems There are number of points which are not clear in your specification and needs more discussion just for example, Also be able to be controlled by temperature sensor/sensores does not convey anything the software and hardware will have to be designed based on what type of sensor it is, sensors value and voltage and current specifications and the control algorithm will have to be designed based on such parameters. What is the output voltage of the solar panel? Only solar panel is present or is there a battery also? What will be the consideration when there is temporary dip in the panel output due to cloud covers? The sentence a view all PIs on one place. indicates that you have a server and multiple Pis will connect tot he server. What type of server it is? What is the protocol? Lot more discussions i required to finalise the specifications Final price will depend on final specifications Can we discuss? Thanks

Hi I can create that project for you ,I have good experiences in embedded systems . I have already create alot of projects using many arduino types and Raspberry Pi 2,3 mode B , I have raspberry Pi 3 model B+ coming in the way if you may need to work on it . about the project as I understand you need to read sensors like temperature sensor and take action when it reach limit you want ,I will use node.js programming language to control that . you didn't mention what you want to do with the arduino . if you want a demo I will do it for free . the budget can be less than that or more depend on the work type .
