Hi all,

has anyone successfully run EVOK API in docker container?

Will there be any official support to run EVOK API in docker?

BR

Tomas,

thank you, putting "-d" in front (bus = -d /dev/ttyUSB0) worked - maybe you could update the evok.conf file with this (as example)

Hi,

i'm trying to add additional 1-wire port to evok (unipi v1.1), by adding usb-1wire converter.

In evok.conf I defined second OW bus by adding:
[OWBUS_2]
bus = /dev/ttyUSB0
interval = 5
scan_interval = 300

but I cannot read any sensors. Any help wil be appriciated.

True, if "cmd":"set" addet to json string, ws command works.

Reliability of ws is not as expected - bmo it is beter to use http post methods.

ps.
Can you please tell what are other commands in cmd?

I did as sugested I grounded cables for 1wire network connection. But it doesnt solve the issue.

I guess it has to be power issue - I have 1x Unipi, 1x Rasperry Pi 3 and 1x EMO-8R module in addition 14x 1wire DS1820 temperature sensors.

I am trying to figure out maximal power needed and so far I come with:
1.5mA/1wire DS18b20
1.5A/Unipi+RPi - 2.5A - RPi 3 model B (but only 1.1A is provided through Uni.pi) in opreational mode 250-500mA, that leaves around 1A for UniPi board and another 750mA for EMO-R8.

Bottom line 2.4A should be enough for uni.pi main board, but not necesaray for extension module - could this cause 1wire lost problems?

Hi,

I am running raspbian jessie recently and I cannot figure out websockets. I can not change relay states trough websocket connection (whic has state connected, aslo if I use websockets as input it works)

I created simple flow (which gives me trouble):

[{"id":"c19d5eed.d773c","type":"inject","z":"a5e9eb30.633008","name":"unipiR2on","topic":"unipiR2on","payload":"{\"dev\":\"relay\", \"circuit\":\"2\", \"value\":\"1\"}","payloadType":"json","repeat":"","crontab":"","once":false,"x":372,"y":338,"wires":[["d9c4b8fa.078788","af5dc7d8.1bc2e8"]]},{"id":"bad348d9.50a668","type":"inject","z":"a5e9eb30.633008","name":"unipiR2off","topic":"unipiR2off","payload":"{\"dev\":\"relay\", \"circuit\":\"2\", \"value\":\"0\"}","payloadType":"json","repeat":"","crontab":"","once":false,"x":382.9000434875488,"y":480.5667152404785,"wires":[["d9c4b8fa.078788","af5dc7d8.1bc2e8"]]},{"id":"d9c4b8fa.078788","type":"debug","z":"a5e9eb30.633008","name":"","active":true,"console":"false","complete":"payload","x":696.0477447509766,"y":179.5238332748413,"wires":[]},{"id":"af5dc7d8.1bc2e8","type":"websocket out","z":"a5e9eb30.633008","name":"","server":"d4a09910.dd7638","client":"","x":778.8095528738838,"y":395.23812430245533,"wires":[]},{"id":"d4a09910.dd7638","type":"websocket-listener","z":"","path":"ws://127.0.0.1/ws","wholemsg":"false"}]

tnx for quick reply - will try to ground FTP cables and will report back.

Update: as mentioned only software reboot is not enough, I have to unplug and plug UNI.pi board to electricity to have 1-wire sensors reading again.

Could it be, that this is hardware problem (for connection I use standard UTP patch cable)?

I'm having trouble with EVOK, when I read 1-wire (DS18D20) sensors in node-red flow, after some time sensors are lost (if I look at uni.pi.ip/rest/all, for sensor ID I get "lost": true). If I restart EVOK service, no 1-wire sensors are shown.

Is there any known solution for this?

PS. I am running Rasbian on RPI3.
