Wireless RS485 connection - EW11

[sfeakes]

There are a few discussions and people playing with EW-11 to connect to the Jandy control panel over wireless connection, so brining all the discussions into one place.

At the moment people have had good results with RS panels, and somewhat ok results with PDA panels. I personally think their will always be problems with PDA panels.

Few threads.
Below has most information, and screen shots of config.
#300

Some more details on settings/config for EW11. Note the GAP setting.

Uploaded all documents here to help. Also attached a picture of the wiring for the EW11.

Hope this helps

bcre3306, seems you and I are working on much the same system pd8-combo.

Just checking. You mentioned changing gap to 10 ms in ew11 per my post. Did you also set:

rs485_frame_delay = 0

did this get rid of your bad packet warnings?

On mine it greatly reduced the warnings, but I still have get on average about 1 per minute. This is much better than the 6+ per minute I had in the past.

I am overloading the comm port, 4 connections as one of my ports is not working. I am curious if you are having better results. I plan to play with wiring to see if I can get some further improvements. Do you have 2 rs485 ports? Do both work?

Thanks!

replying based on thread 333.

The temperature issue I mentioned in earlier thread seem to do with:
convert_mqtt_temp_to_c = yes
convert_dz_temp_to_c = yes

my temps are in F. 104, and 70. With these settings on, it is taking them as c and converting to f. 104 goes to 219. 70 to 158. Then tried to update.

Changing to no corrected the issue.

@sts098 sorry I have a different panel(RS4 Combo). I haven't tried the frame delay setting but I am getting an error more then once a min but MUCH cleaner then it was. I'll give that a try and report back in a little while. My temps are coming across correctly also

[sts098]

I get temps, pump rpm and watts. I see changes to pump, cleaner, waterfall, spa and heater. Most of these I can control. Variable speed pump is a little hinky. Can get out of sync on Mqtt and Aqualinkd. Haven’t been able to repeatably isolate issue yet.

The only warning I really get now(minus packet drops which are because I need the EW11 with the external antenna which is on order) are the ones below. I get them about every 10 seconds

Warning:RS Serial: Read Jandy packet BAD PACKET To 0x33 of type Unknown '0x72' | HEX: 0x10|0x02|0x33|0x72|0x20|0x01|0x02|0x03|0x04|0x05|0x06|0x07|0x08|0x09|0x0a|0x0b|0x0c|0x0d|0x0e|0

From looking at the log you posted in a different thread. I think that the bad packet you are seeing, is due to a protocol change in Board Rev Yg that has changed, and not an actual RS485 issue with the EW11.

I will look at posting a fix for this in the next release.

After some initial testing with different panels, I have found the following settings to work best for EW11.
For socat. (change IP 1.1.1.1 to you EW11's ip)

socat -d -d pty,link=/dev/ttyEW11,raw,ignoreeof TCP4:1.1.1.1:8899,ignoreeof

In AqualinkD the below are important (port matches above, no frame delay)

serial_port=/dev/ttyEW11
rs485_frame_delay = 0

On the EW11. Note the buffer and gap time are set to the minimum.
