GreenWave PowerNode 1 port strange values

[rolandbreedveld]

I have 2 "GreenWave PowerNode 1 port" switches also the 6 port version of it.
With both of my 1 port switches I sometimes see strange values in the power measurement, sometimes in numbers above 1 Mwatt, which of course is not possible.
Both in the Watt and kWh counters.

Example:
12 Friday 0.397 0.100 0.02
13 Saturday 0.497 0.100 0.02
14 Sunday 0.597 1342180.907 288434.68
15 Monday 0.000 0.715 0.15
16 Tuesday 0.084 0.100 0.02
17 Wednesday 0.184 0.101 0.02


I think it can be a structural hardware issue, or a driver issue.
someone any idea how to fix this ?

I am seeing the same strange values some times.

when looking in the table meter_calendar (kWh) , I see this:
48|46|994|2017-09-14
48|46|1041|2017-09-15
48|1087|1087|2017-09-16
48|31|1119|2017-09-17
48|29|1148|2017-09-18
48|28|1176|2017-09-19
48|1204|1204|2017-09-20
48|1233|1233|2017-09-21
48|31|1264|2017-09-22
48|30|1294|2017-09-23
as you can see the value field is sometimes filled with the counter field

looking at multimeter_calendar (W):
41|0|53|24.49|0|0|0|0|0|0|0|2017-02-10
41|0|54|24.29|0|0|0|0|0|0|0|2017-02-11
41|0|54|24.2|0|0|0|0|0|0|0|2017-02-12
41|0|5059|881.06|0|0|0|0|0|0|0|2017-02-13
41|0|0|0|0|0|0|0|0|0|0|2017-02-14
41|0|53|4.53|0|0|0|0|0|0|0|2017-02-15
41|0|55|23.6|0|0|0|0|0|0|0|2017-02-16


the failures compared between the W and kWh tables are not at the same day

Looking on other devices, I see it is a structural Domoticz problem
The most Z-Wave devices have this problem,

here from a Fibaro 223 device:
211|60|8640|2017-09-18
211|60|8700|2017-09-19
211|8750|8750|2017-09-20
211|40|8790|2017-09-21

a fibaro 222 (roller-shutter)
81|10|5730|2017-09-01
81|0|5730|2017-09-02
81|5750|5750|2017-09-03
81|10|5760|2017-09-04

Greenwave 6-block:
42|66|687|2017-09-23
42|754|754|2017-09-24
42|66|820|2017-09-25

NeoCoolCam Power Plug:
262|170|9630|2017-09-25
262|9740|9740|2017-09-26

Sometimes, also the counter value is wrong:
81|20|2760|2016-09-01
81|40|2800|2016-09-02
81|20|2820|2016-09-03
81|406780|409600|2016-09-04
81|406780|2850|2016-09-05
81|10|2860|2016-09-06
81|10|2870|2016-09-07
81|10|2880|2016-09-08
81|0|2880|2016-09-09
81|286120|289000|2016-09-10
81|286120|2910|2016-09-11

You can see it for yourself with this query:
sqlite3 domoticz/domoticz.db "select * from meter_calendar where value=counter and value<>0 and value>1000 ;"
(some values can be correct)

I repaired all values with a script and a sql update, but it's strange, this should not be...
