I have a sewage treatment plant and the blower stopped working. Looking at the house use graphs on Emoncms, I was able to see when the base house usage dropped by about 40W and that it had been off for just over a month!
It occured to me that it would be handy to have Emoncms notify me should this happen again in the future. Googling around the subject, it seems I should be able to use the eventp module’s ‘send email’ process on the inputs page. I can’t find any documentation on how to set this up other than:
It means exactly that: jump directly to Step 8. If there isn’t a Sep 8, it falls off the end.
You look at it in conjunction with the step before, if >=, skip next.
If the value at step 2 is 20 or greater, processing jumps to step 4. Otherwise, it falls through to step 3 and then jumps to step 8.
The same happens with steps 4 & 5.
I have exactly the same problem. When the blower diaphrams fail, the blower trips and often I don’t notice until the system starts to smell. My blower draws about 75W when operating. The minimum total load during the quiet hours is about 190W.
I run a NodeRed script once a day that looks for the minimum load during the quiet hours and generates a report when it drops below 150W. I use a servce app called Pushover to push any reports from my system to my mobile phone.
I had read that some folks use nodered to set up alerts but as I have never used it and would have to learn it, it seems easier if it can be done all within Emoncms.
I will continue and see if I come up against any more issues…
