I have started to add several Sonoff POW R2 around the house, which monitors the power just fine. I had to flash them with Tasmota firmware, and then use MQTT to add them to openhab. Works fine.
I have no reason to reset the saved power value each month. Insted I believe persistence would be better, in case I need to know, how much energy a device had been pulling for a month.
I also got a TP-Link HS110. It does the job fine as well. But its not in use atm.
The Rainforest Eagle is limited by support from the local hydro company. Looks like the way it work is that the hydro company sends the electricity snapshot to company cloud and that is then pushed to your loal network. They only have support in a few states/provinces now.
Why is that a problem? The whole point of openHAB is to take all the devices and control / view them from one place
I have a mix of (roughly) the following:
4 x TPLink 110
10+ Sonoff POW with Espurna + mqtt
LightWaverf (gen 1) ct transformers on the mains feed and the solar invertor
I have some Sonoffs on the low-current lighting circuits, some on appliances that don’t move. The 110s are on the heavy stuff like washing machine and tumble dryer.
I have it mapped out to show the net usage of the house (net = house - solar), which circuits on those are using how much and, for some, which appliances are using it within that circuit.
From that, and logging it, I can use Grafana to draw some pretty interesting (or just pretty ) graphs.
I would like to swap all sockets in the house for the new gen2 ones because monitor power too but seeing as mine are notthatold and the new ones cost £60 each, it’s a tall order
If you’re feeling experimental, there are these products coming onto the market:
I am not sure I would use one those as it is a fundamental protection device and, should it fail to do it’s job, fire or death is possible.
That depends on your comfort level. The short version is: take off panel cover, open the clamps, put them around the wires, put it back together. It’s quite simple but some people aren’t comfortable doing this sort of thing.
From within the Kasa App, I haven’t been able to do much with stored data from Energy Monitoring on the HS110. Now, if openHAB has the ability to retrieve all such information from HS110, then that’s way more interesting.
You can get local access with the Rainforest Eagle. There’s a binding for it. It works; I’m using it. Not going to the cloud - in fact I disabled the Eagle’s access to the Internet from my router so it is completely local. You can get data from the cloud if you choose, but you don’t have to.
I’m not saying this is the best solution, but it does work for whole house monitoring. That’s how I get these power and energy charts.
It does depend on your energy company allowing smart meter access.
No, it does not get it from within the 110.
The 110 has a binding in OH which, every time the value changes, updates an item in OH.
OH has persistence which you set up and store that value to mysql
You then use grafana to read that data and display it as a graph.
can i see your setup ,how you did (items,sitemap) and so on ?
im not a coder so i have a hard time setting things up my self, i have the Aeotec installed and i can see alle the numbers ,but i wood like to see have you did if its allright please
ps: i am condesitring to buy on more to my solar system ,but do
you have an idea how to show some calculations on how mutch
power you are pooling from the net or putting on the net ?
I haven’t spent a lot of time doing any calculations/rules for this. at the moment i’m just doing simple stuff like displaying total KWH pulled from the grid, total solar KWH produced and the different between the two
it’s something i’ve been meaning to do, i just haven’t gotten there yet
do you show your conf. files somewere ? github or somewhere ,so that i can see how your config files are made ?
I`m not a coder so i wood like others that are too show their conf. please !
I have the Aeotech Home Energy Meter but i need to do some calculations (grid - solar ) and cost , can you help by showing how
There is nothing to show beyond the Rule I’ve already posted above. The device is zwave and was automatically discovered. The database and charting is using default configs that come from InfluxDB+Grafana persistence and graphing
